Terry J. Reedy added the comment: Biggest change is no support module in 2.7, so in test_idle.py import inside try:except to skip if dependencies not present. Minor changes in CallTips.py and test_calltips.py. Buildbots are fine. This meets my initial goal; issue done. I opened #18103 for consideration of gui tests. But except for improving the existing no-buildbot, human-needed tests, I consider that a lower priority right now. -- resolution: - fixed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Ned Deily added the comment: The test.support module was renamed in Python 3 from test.test_support in Python 2.

R. David Murray added the comment: Heh. Yeah, I use patch because I don't just work with mercurial/python, and I find the patch command simpler to use for applying patches in general, since I never want an autocommit. (The exception would be if I'm applying a patch that involves extended diff stuff that patch doesn't recognize.) It makes sense that the devguide talks about import, though, since the patches here always ought to be things generated by hg and thus handleable by import.

Terry J. Reedy added the comment:
Before committing, I experimented with disabling test/test_idle. The simple and
safe method is to comment out the 'load_tests' line. With no tests discovered,
all pass ;-). Without verbosity, there is no indication that there were none. A
little harder, and needing to be tested for typos before committing, is to add
this line before that line:
import unittest; raise unittest.SkipTest('skip for buildbots')
Regrtest (py -m test test_idle) registers the unexpected skip. Unittest (py -m
test.test_idle) exits with a traceback. This is recorded in an updated README,
which also incorporates Todd's suggestion. I also touched up test/test_idle.py.
If buildbots do not break, I will work on 2.7.

Terry J. Reedy added the comment: Last I checked, test_idle passes on the stable buildbots. But it fails on a machine without threads, such as http://buildbot.python.org/all/builders /AMD64%20Fedora%20without%20threads%203.3/builds/752/steps/test/logs/stdio On this machine, thread-related tests are skipped: some seem expected, some not. The chain of imports is test_pathbrowser - PathBrowser - ClassBrowser - PyShell - threading - _thread. Since a PyShell import is required to run Idle (PyShell.main), even with just the editor, I will put the _thread import check in test_idle itself rather than sprinkling it throughout the test suite as dependencies are discovered. (Besides the bother of the latter, the dependency could go away if PyShell only uses threading to runs user code in the same process, or delayed if it is used for other features that might not be used.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

With this additional confirmation, I am about ready to commit -- when I feel fresh and ready to monitor the buildbots. But I notice that the non-executable @README has 7 ways to run all or part of the suite, most of which have appeared in this issue. Even with history retrieval, I am tired of retyping to test changes. I should have started with an executable test suite test (.bat or .py using subproccess for the command lines). Then I could have just added the two cases above and re-run after today's edit.

Terry J. Reedy added the comment: The change to the two idlelib/*.py files enables those files to run their corresponding idle_test/test_*.py file when run as a main script. They have nothing to do with running test/test_idle.py. So please try running the latter. python -m test.test_idle # direct, without regrtest python -m test test_idle # indirect, with regrtest I upgraded(?) TortoiseHG (2.8, with hg 2.6) and found the setting for Notepad++ to create new files in 'unix/osx' format, which I presume refers to line endings. Does the new file apply better for you? If so, I will try to always use this for uploaded patches. --- Question: when I import this patch (either format) to 3.4, it applies the chunks and makes the changes with no apparent problem, but then 'aborts' -- but not really, because it leaves the changes: abort: edit failed: vi exited with status 1 [command returned code 255 Mon May 20 23:08:16 2013] The appear to be a failure of the commit message editor? If so, it is tolerable, but it worked a week ago (regression in upgrade?), though i have seen it before. Manual says If the patch you are importing does not have a commit message, Mercurial will try to launch your editor, just as if you had tried to import the patch from the command line. Your ui.editor needs to be a GUI app to make this work correctly. I get same message after setting editor to notepad or notepad++, so 'vi' mystifies me.

Terry J. Reedy added the comment: I was really sure that 'python_d -m test' worked a week ago, in the sense that test_idle was run without incident in its proper alphabetical sequence, before I said so and uploaded the patch. Now, there are (different) error messages with both 'python_d -m test' and 'python_d -m test test_idle'. (I did not try the latter before, only 'python_d -m test.test_idle', with the added '.' whose importance I now understand.) One of the two error messages includes what David reported. When I can, will report the other, and also will try to 'hg update' to a week ago to reproduce the remembered success. If I cannot, I will try options to determine the boundaries of the bug in the interacton between unittest and regrtest and a decent workaround that avoids duplicating code while running under both unittest and regrtest. I sent Todd the Windows files to examine, modify, and test. (Nick: neither unittest nor regrtest can run tests hidden within patches on the tracker.

Nick Coghlan added the comment: Just a quick note on the directory naming: idlelib/idle_test sounds like a good option to me. Putting it under idlelib makes it easy for distros to carve it out along with the rest of Idle, as well as making it clear that it falls under the purview of PEP 434 Expanding Itest - idle_test is a combination of Itest being somewhat cryptic in the first place, and then the potential for 1/I/l/i glyph confusion (depending on font) making it worse.

[issue15392] Create a unittest framework for IDLE
Terry J. Reedy added the comment:
Ezio, thank you for the response.
1. I care more about where the directory of tests is than what it is called.
'idle_test' or 'idletest' or whatever would be fine. Lets make that the last
bikeshed item ;-).
2. I looked as #10572. It was originally about moving unittest tests from
unittest/xx to test/yy, and then broadened to other packages. Michael F. gave
two reasons for the move.
2A. Easier to grep without recursing into the test directory. Barry already
refuted this, pointing out that grep/find have options to not recurse. The Idle
equivalent, Find in Files, has a little checkbox
[] Recurse down subdirectories.
I think Michael had this point backwards. The advantage of having tests with
the code is to make grepping both at once possible. I am sure I will want to do
this while developing the tests. So add this to my list of reasons to put the
directory under idlelib.
2B. Would honor the Windows Install without Tests option. This is strictly a
matter of saving space by disabling function. I agree that this is appropriate
for nearly all packages, but I already explained why I want to evade that
option: tkinter and idle are exceptional in that they are the only two packages
that people regularly have problems running. So I think people should have
those tests available, even if none of the others.
2 (again). Other people opined that package maintainers should have some say in
the matter and that there might be exceptions.
3. Many modules have more or useless 'sanity-check' tests run with the 'if
__name__' mechanism. I think *all* of these should be replaced with
unittest.main(xxx, verbosity=2, exit=False) to run the full test module. If the
code module test has anything valuable that is not in the test module, it
should be moved there; the rest should be deleted.
I plan to eventually do this with all such 'tests' in idlelib/*.py. However,
this needs to be done one by one. Some current tests have program errors; my
'file' to 'open' patch last week was the first fix. Some put up a blank window,
with no indication of what a person is expected to do to perform the test. Some
put up a window that will not close by normal means. All except the two in
idletasks.diff require human intervention, which is not acceptible for
buildbots. Question: is there a way for a test to detect being run by a
buildbot?
4. I already used @template.txt to alter CallTips.py and start test_calltips.py
and I want to use it for all the other 60 (or whatever) test files. I will
(re)read the test-writing section and possibly suggest a patch. But
Idle-specific info and code does not belong there.
(5.) unittest.SkipTest is what I was looking for. I do not believe that
support.import_module() will allow skipping if, or unless, the test is running
on a specific platform. I need to look at #16935.
Is Idle CPython only? If so, that should be a condition of test/test_idle.py
running. Ah, testing the imports of tkinter and idlelib already takes care of
that.
(6.) My concern and possible confusion about raising exceptions came from
Jayakrishnan's patch
+def test_DirBrowserTreeItem(self):
+# Issue16226 - make sure that getting a sublist works
+d = PathBrowser.DirBrowserTreeItem('')
+d.GetSubList()
in relation to the doc saying Note that in order to test something, we use one
of the assert*() methods provided by the TestCase base class. There is no such
method. The doc follows with If the test fails, an exception will be raised,
and unittest will identify the test case as a failure. Any other exceptions
will be treated as errors. The 'test above is to raise, or not, an 'other
exception' and I took 'treated as errors' to mean that raising an 'other
exception' is an error. It certainly makes test failure counted as an error
rather than an error and indistinguishable from test code errors. I guess when
the test is fleshed out, there should and will be some assert about the result
of d.getsublist(). So I could delete the try-except.
(7.) A human-intervention resource. I will leave that for later.
My next step after this one is moving tests from CallTips.py to the new
test_calltips.py (3. above).

[issue15392] Create a unittest framework for IDLE
Terry J. Reedy added the comment:
For future reference, there is an idle specific issue that I do not think has
been mentioned yet. Idle can run in one process, but the default mode now, and
perhaps only mode sometime in the future, is two processes communicating
through a socket. Testing two process communication requires two test
processes, not just one. Tests will pass in one process without testing the
full normal process. For instance:
def fetch_tip(self, expression):
try:
rpcclt = self.editwin.flist.pyshell.interp.rpcclt
except AttributeError:
rpcclt = None
if rpcclt:
return rpcclt.remotecall(exec, get_the_calltip,
(expression,), {})
else:
return get_argspec(get_entity(expression))
I believe this works because fetch_tip executed in the idle process makes a
remote call that results in fetch_tip being executed in the remote process,
where self has no editwin and hence control falls through to the last line.
A normal, naive test of fetch_tip will 'work' because it will simply fall
through to the last line, which in this case is mostly redundant with separate
tests of get_entity and get_argspec. It seems to me that a full test suite must
at some point test that the actual communication works, and that this cannot
all be done with mocks.

[issue15392] Create a unittest framework for IDLE
Ezio Melotti added the comment: Having idle_test under idlelib is fine with me if it makes your life easier. 3. Many modules have more or useless 'sanity-check' tests run with the 'if __name__' mechanism. I think *all* of these should be replaced with unittest.main(xxx, verbosity=2, exit=False) to run the full test module. If the code module test has anything valuable that is not in the test module, it should be moved there; the rest should be deleted. All the sanity checks (at least the reasonably sane) should be converted to unittest and moved from the modules to the respective test_* modules. The others should be removed, and I don't think we have to keep the if __name__ in the modules (the test modules should have it though). Specifying the verbosity=2 in all the test modules might not be a good idea. If you are running all the tests at once, that level of verbosity will just get in the way (and I'm not sure you can change it easily). If you are running individual tests modules you should be able to change the verbosity from the command line. Question: is there a way for a test to detect being run by a buildbot? You can handle this by adding a new resource to test.support. The tests will normally be skipped unless you explicitly run them using ./python -m test -uhumanneeded or you run the test file directly (you can enable the resource in the if __name__). 4. I already used @template.txt to alter CallTips.py and start test_calltips.py and I want to use it for all the other 60 (or whatever) test files. I will (re)read the test-writing section and possibly suggest a patch. As I suggested earlier, I think the main function in Lib/idlelib/CallTips.py should be converted to unittest and moved to test_calltips. CallTips.py should not include any test-related code and no if __name__ IMHO. But Idle-specific info and code does not belong there. Agreed. Actually once the initial conversion is done I don't think documenting it so important, since it will be easier to look at all the others tests and see what they do than finding the documentation that explain how things should be done. (5.) unittest.SkipTest is what I was looking for. I do not believe that support.import_module() will allow skipping if, or unless, the test is running on a specific platform. I need to look at #16935. Nope, but you can do if sys.platform() == '...': raise unittest.SkipTest(...). The TL;DR version of #16935 is that it will break test discovery on 3.3, but that's not a big problem. (6.) My concern and possible confusion about raising exceptions came from Jayakrishnan's patch Either if you get a failure or an error, it still means there's something wrong :) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15392] Create a unittest framework for IDLE
Terry J. Reedy added the comment: Tests have at least two very different purposes. One is test-driven development of code (and tests) by developers. The other is regression detection by buildbots. if __name__ in code modules, in addition to test modules, makes the first much easier. First, the unittest.main call in the test module must be appropriate for the buildbots. Since buildbots do not execute the corresponding call in the code module, it can and and should tuned for development, which I have done. The 'if' block is also a place for any other code specific to developer tests, such as enabling a 'humanneeded' resource. Second, when editing with Idle, F5 in an editor window runs the test in the Idle shell, where right-click, click on a traceback line takes one back to the corresponding file and line. At least on Windows, using the console and console interpreter is painful by comparison. All this is true when editing any Python file, not just Idle files, so I would be disappointed if someone went through the st dlib deleting, rather than revising the 'if __name__' blocks. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Nick Coghlan added the comment: Terry, the unittest and regrtest command lines are *built* for TDD - you rely on test discovery and selection to run the appropriate tests for what you're working on. However, the point about F5 in IDLE is well made, and a reasonable rationale for ensuring at least the IDLE implementation files support running their tests that way. While it doesn't need to be extensive, it would be good to capture some of these points in a Idle/idle_tests/README file. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15392] Create a unittest framework for IDLE
Terry J. Reedy added the comment:
Attached is a 3.3 patch that I *believe* is ready to commit and push.
With my Win7 repository build, I tested running one test from a file (after if
__name__ == '__main__':) or command line ('python_d -m idlelib.PathBrowser');
all idle tests with an interactive interpreter (console or idle shell, see
@template.txt for input); all idle tests from the command line ('python_d -m
test.test_idle'); and idle tests as part of the CPython suite (python_d -m
test). I also tested versions of all but the two batch-mode tests in my 3.3.1
installation.
From what i know, I do not believe there should be much issue with the
framework working on non-Windows systems. But I would not mind verification. I
presume this patch will work as is with 3.4, but ditto. 2.7 may need one tweak
noted below. (Testing with 2.7 is difficult for me at the moment.) Nick: yes
to your 2.7 plan. PEP 343 changes things.
Once applied to all three branches I think this patch is enough to close this
issue and 'get the ball rolling'. Mock, gui testing, and any other big problems
should be separate issues.
The patch adds
Itest/__init__.py (merges doc example, part of previous __init__.py)
Itest/@template (for both test_x.py and startup from x.py)
Itest/test_calltips.py (with first 2 of many tests)
Itest/test_pathbrowser.py (revised, with 1 test, see note below)
test/test_idle.py (revised skeleton of previous __init__.py)
and revises
CallTips.py
PathBrowser.py
to run the corresponding tests when run as '__main__'.
Question: Unittest supports skipping individual test methods and even whole
classes of tests How about skipping (possibly conditionally) an entire file --
especially test_idle, which has no classes, or and test_xxx with multiple
classes?
For multiple reasons related to the fact that Idle and idlelib *are* special,
as recognized by PEP 343, I want to keep the individual test files in an
idlelib subdirectory. as with tkinter tests. (I changed the name from 'test',
so that 'import test' will a always import Lib/test.)
* Once in idlelib, changing to Itest is easier than to ../test/test_idle. With
62 .py files in idlelib, we will be opening pairs of files a lot.
* Copying code and test files to another directory, such as an installation
idlelib/, will be easier. I will be doing that to run with new features and
test things in the installation environment.
* PEP343 makes most of idlelib/* a private arena. Test/* is a public tree
mainly for the buildbots. Tests put there are supposed to pass. In brief, I
personally feel much more comfortable mucking around in a private arena with a
small public window that can selectively open and closed as needed.
* We need an Itest directory anyway for things that do not belong in test/*.
@template is an example, and I have in mind a couple of non-buildbot test
scripts. We may also want an idle-specific support module, as tkinter has.
* Once people install Python so it runs, some still have problems running Idle.
They ask a class instructor or someone else; post here, python-list,
stackoverflow, or elsewhere; or give up. Sometimes the problem is with tkinter,
sometimes with idle, sometimes with their knowledge. A good diagnosis script
should save support time and user frustration. Both tkinter and idle tests
should be available for this. The Windows installer makes the 17 mb of test/*
optional.
Other changes from the previous patch:
* Use unittest.main to run tests.
* Guard test_idle execution with tkinter import, as it is _tkinter, not idlelib
that might not be built. I left the guard for idlelib since someone who deletes
idlelib/* might forget to delete test/test_idle.
* Exceptions raised outside of self.assertXyz (and self.fail) calls are
regarded as an error in the test code rather than a failure of the code tested
(26.3.4. Organizing test code). So, there being no 'assertNotRaises' context
manager, I added try:...except ...: self.fail() to test_pathbrowser.py so a
failure will be reported as such and not as an error. If there is a better way
to do this, let me know.
Since 3.x chains exceptions and prints the original traceback, no message
argument is needed with self.fail to explain the failure. For 2.7, I believe
one should be added.
Note: to empirically test that a test fails properly, it must be run with code
that does not work properly. This is a problem with writing tests after the
fact for code that works properly.
I checked all 62 idlelib/*.py files for a test to see what we have to work
with: the answer is 'not much'. Less than half the files have a test. All but 2
that do bring up a window and require a human to key, click, and look according
to a script that is not provided. (This is not to say that the existing code
will not be helpful for some gui tests.) One of the 2 remaining text tests
prints multiple pages (a config file) for a person to check. By coincidence,
the only automated tests

[issue15392] Create a unittest framework for IDLE
Ezio Melotti added the comment: A few comments about the patch: 1) I would prefer a more explicit idle_test instead of Itest (assuming I means idle); 2) having idle_test in Lib/test would be better if possible (see #10572); 3) the tests should only be in idle_test, and not in the if __name__ == '__main__': of the files; 4) I'm not sure the @template file is necessary. It could be documented somewhere else though (see e.g. http://docs.python.org/3/library/test.html#writing-unit-tests-for-the-test-package). IOW putting all tests in a separate dir is a good thing, and the dir could either be in Lib/test or in Lib/idlelib. All the tests should be inside this dir, except for Lib/test/test_idle.py that should be the entry point used to run all the tests in idle_test (see e.g. the tests for ctypes, email, and json). Individual tests in idle_test can be run on their own, and they should use the if __name__ == '__main__': unittest.main() idiom. Question: Unittest supports skipping individual test methods and even whole classes of tests How about skipping (possibly conditionally) an entire file -- especially test_idle, which has no classes, or and test_xxx with multiple classes? You can raise unittest.SkipTest or use support.import_module(). This works fine if you run the tests through regrtest, but be aware that unittest itself only sees this as a skip from 3.4 (see #16935). * Exceptions raised outside of self.assertXyz (and self.fail) calls are regarded as an error in the test code rather than a failure of the code tested (26.3.4. Organizing test code). So, there being no 'assertNotRaises' context manager, I added try:...except ...: self.fail() to test_pathbrowser.py so a failure will be reported as such and not as an error. If there is a better way to do this, let me know. If it's supposed to work the try/except is not necessary IMHO. By this logic every line of code should be wrapped in a try/except :) Since 3.x chains exceptions and prints the original traceback, no message argument is needed with self.fail to explain the failure. For 2.7, I believe one should be added. If you still want to keep the try/except, I would provide a meaningful failure message in any case. Note: to empirically test that a test fails properly, it must be run with code that does not work properly. This is a problem with writing tests after the fact for code that works properly. It's not difficult to break the code to test that test works though :) I checked all 62 idlelib/*.py files for a test to see what we have to work with: the answer is 'not much'. Less than half the files have a test. If possible I think these should all be moved to idle_test.

[issue15392] Create a unittest framework for IDLE
Nick Coghlan added the comment:
I've added 2.7 to the affected versions - the core unittest framework should be
present in all 3 versions, so the choice of if/when to backport a fix and its
test can be made on a case-by-case basis, rather than being a foregone
conclusion due to the lack of IDLE test infrastructure in 2.7
If/when mock is used in any tests, then a compatibility module isn't actually
needed, 3.3 and 3.4 can just use from unittest import mock while 2.7 can use
mock = support.import_module('mock') (so those tests will run if you arrange
to make the mock backport from PyPI available when running the tests, but will
be skipped otherwise).
Terry, are you happy with that plan? If so, over to you to get the ball rolling
and commit this as a starting point :)

Ezio Melotti added the comment: If things are fixed/added/improved on 3.x, there should be tests for them, and if they are backported on 2.7, tests should be backported as well. If mock makes testing easier, I think it would be acceptable to use it and then have IDLE devs install a 2.7 mock and use it to run all the tests. The tests on 2.7 could use skip decorators to be skipped if mock is missing, without having to keep these tests separate from the rest. If necessary a script to install mock on 2.7 could be provided, and possibly used by the buildbots too. This means that the initial framework should be backported, otherwise it won't be possible to backport any of tests that are going to use it.

R. David Murray added the comment: I think the issue of whether/how to test Python2 idle should be discussed on idle-dev. One strategy is to make the tests backward compatible (so no mock). Another possible strategy is to have an extra bit of test framework for IDLE in 2.7 that copies the tests and mock from another location in order to run tests against 2.7. That is, the tests wouldn't be an official part of the 2.7 repro and would not be run by the buildbots. The reason for doing that would be to allow the Python3 tests to be as rich as possible while still doing some testing on 2.7.

[issue15392] Create a unittest framework for IDLE
Terry J. Reedy added the comment: When I opened this last July, I intentionally left off 2.7 for multiple reasons. 1. I knew that the new-in-3.3 mock module would probably be needed for some types of testing. (As for 3.2: at that time, I expected 3.2.4 to be released in September or October, just after 3.3.0, as would have been normal.) 2. 2.7 is yesterday's horse. I hope we fix disabling bugs before maintenance stops. I do not expect all new features to be backported. I personally have no motivation to do so if a patch does not apply cleanly, or nearly so. Also, I knew that a full test suite would not happen instantly and that 2.7 maintenance would probably be tapering off by the time one was fully in place. 3. My experience with calltips #12510: I fixed IDLE closing bugs for all versions. I did not backport all the text display improvements; the 2.7 code was different partly due to dealing with old-style classes. I did not backport the new tests I added in msg162510 and msg165057. They depend matching exact texts. They will need to be changed again when calltips are adjusted to the new multiline signatures in builtin-function docstrings. The will probably need to be changed if calltips are changed to use the new-in-3.3 signature objects. There are proposed 3.4 changes for compiling C functions that might impact calltips. 4. There was no PEP 434 ;-). While *I* considered the relaxed backport policy to be the defacto policy then, it *was* a bit fuzzy, and others disagreed. With the PEP accepted, I am more open to backporting at least some tests if someone else (like Tomoki) does most of the additional work. (I plan to start with this issue when my development machine is back from repairs and proper set up again.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15392] Create a unittest framework for IDLE
Jayakrishnan added the comment: The aimed versions for this unit test frame work is python 3.3, 3.4. So as Nick said, unittest.mock may have no issues on this. As you said 3rd party modules seems not a better way.But the link you provided ( https://pypi.python.org/pypi/mock ) says .. mock is now part of the Python standard library, available as unittest.mock in Python 3.3 onwards. And yes, GUI testings While I was writting my proposal on this project Todd.Rovito mentioned me .. you should still complete some GUI tests so future developers will have a model. -- nosy: +JayKrish ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15392] Create a unittest framework for IDLE
Jayakrishnan added the comment: There is a need of a proper design in whether to put tests in test sub directory or to create idlelib/test directory. For my GSoc proposal initial draft, I suggested to start with Put tests in test/test_idle directory (like test/test_email would be the best practice). Test for the presence of idle and skip if idle is not available. Move the existing,pending tests for idle ( http://bugs.python.org/file27613/issue16226_test.patch , http://bugs.python.org/file24075/test_idlelib.py,) into this directory. (which my patch 15392_idletestframework_1.patch did for me) Considering the point terry.reedy mentioned, Adding test/test_idle will not be too much use until issue #10652 is resolved so it would actually run with -m test, my view is, the issue #10652 on this message is on a healthy patch review, so it would actually run with -m test in near-future Expecting your suggestions on this design decisions. -- keywords: +patch Added file: http://bugs.python.org/file29973/15392_idletestframework_1.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Tomoki Imai added the comment: I'm a student thinking of participating in Google Summer of Code. And want to work to create a unittest for IDLE. Using unittest.mock seemed to be good way to test GUI. But there is a problem. There is no unittest.mock in Python2. http://docs.python.org/2/library/unittest.html I think using third party mock seemed to be ok, but not best way. https://pypi.python.org/pypi/mock Because, IDLE is a part of official python. I think relying on third party module is not good. Of cource, I would forcus on non-GUI unittest. But GUI-test would be needed. -- nosy: +Tomoki.Imai ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15392] Create a unittest framework for IDLE
Nick Coghlan added the comment: I'll start with a bit of philosophical guidance :) 1. As much as possible, push logic testing down into the non-GUI tests. Where unittest.mock can help here is when you have a piece of code to test that is *almost* independent of the GUI, but needs to call an API to either get input from the user or to send something to the screen. unittest.mock can then be set up to intercept that call, either to check that it happened as expected (display operations) or to provide a predetermined answer (input operations). 2. For the GUI tests, unittest.mock is likely to be most useful in providing predetermined input. There's only so much you can do with this, it's ultimately about ensuring that the code tested against mocked out APIs in the lower level tests at least doesn't throw exceptions when tested against the real APIs. Proper GUI testing is actually a much harder test automation problem, so it probably makes sense to focus on the non-GUI tests for now. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

R. David Murray rdmur...@bitdance.com added the comment: The screen flickers a bunch, so something involving my display is certainly happening. As for runtktests...test suites that live in the package as opposed to the test directory require support files to gather the tests to be run. This can be done by the test_.py file in the test directory (which is what regrtest runs), or it can be done in a function imported from the packages test directory. For tkinter it looks like the test gathering is done in runtktests. Most Python test_ file can be run directly to run the relevant tests, and runtktests works the same way. So yes it is a runner, but that appears to be a convenience just like for other test_ files, and not anything special. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15392] Create a unittest framework for IDLE
R. David Murray rdmur...@bitdance.com added the comment: All the tests should run from the standard test runner tool (currently regrtest), with the GUI tests guarded by the GUI resource, which is how it works for TK. I always run the test suite with -uall before non-trivial commits, so I do in fact run the TK gui tests on a regular basis. I would do the same with idle. I hope there are at least a few other developers that run with -uall on a regular basis :) Whether or not there is value in a separate runner is a separate question. If there is value in having one to you and the other people working on idle, then make one. But for those of us who touch it only occasionally, the separate runner is not likely to get used. I wasn't even aware there was one for tkinter. There was a push a while back suggesting that best practice would be to have all tests be in the 'test' subdirectory. I moved email/test into test/test_email, and I prefer having it there. On the other hand, Michael prefers having unittest/test, and has kept the unittest unit tests there. So that part is up to you, but I encourage you to consider putting them in the test subdirectory, and if you want to do that I would help out with moving the existing tkinter tests to the 'test' dir. And yes, either way the tests should test for the presence of idle and skip if idle is not available. -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Terry J. Reedy tjre...@udel.edu added the comment: I have not really used unittest, so I only know to blindly copy what has been done. Hence I need help to do better. Do you actually get gui tests for test_tk? When I run test/test_tk from Idle editor, and hence as __main__, I only get non-gui tests in spite of enable_gui being set True. Or maybe I just did not see them. (This is actually an improvement over the normal failure of test_tk on Windows. See #10652) Is tkinter/test/runtktests properly called a test runner? test/test_tk uses it to gather the tests to run: support.run_unittest( *runtktests.get_tests(text=False, packages=['test_tkinter'])) It is used within the ttk tests also. As I suggested above, I do not really know if we really need the equivalent. I strongly prefer idlelib/test since it will make developing **much** easier for me on Windows. Also, it would be part of the optional install of idlelib, as tkinter/test is for tkinter. Adding test/test_idle will not be too much use until issue #10652 is resolved so it would actually run with -m test. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15392] Create a unittest framework for IDLE
New submission from Terry J. Reedy tjre...@udel.edu: Idle needs a unittest framework for module test modules. This means a test directory with at least one test module, a runtest module that successfully runs that test module, any new support functions needed for that test module, and inclusion of test_idle in Lib/test. I am thinking of something like Lib/tkinter/test, but without subdirectories. I presume there should be something like tkinter/test/runtests, but I do not know if it reflects current best practice, nor whether it should be in idlelib or in idlelib/test. One feature of runtests and the tkinter framework is separation of tests that do and do not require a gui. This requires cooperation of writers of each test module. Buildbots can only run tests that do not require a gui and nearly everyone else wants the same. On the other hand, we need automated gui tests too. A complete test of idlelib/runtest requires a test module with both kinds of tests. List/test has test_tk. It runs tests with enable_gui=false unless run directly (and intentionally) as the main module. (Testing test_idle would also require tests in both modes.) It checks that tkinter is available. Should test_idle also check that idle is available? (On Windows, one can install both or neither. I don't know the situation on other systems.) This issue was inspired by #12510 and is interdependent with it. As part of that issue, I would like to convert the expanded test set to run under unittest. #12510 needs a place to put a test_calltips module. On the other hand, this issue needs a test_x module to test runtests and test_idle. tkinter/test/support has functions that can be used in idle tests, in particular, simulate_mouse_click(). I believe a needed addition is simulate_text_entry. That is needed to really finish the calltips tests. Currently, complete testing of tooltips requires non-automated hand tests. Would simulate_mouse_click include selecting menu items, or would that be a separate function? With such a test framework established, we could start adding tests as part of other issues, as is normal practice. (Note: tkinter/test is pretty skeletal, and probably could use expansion, but except for support functions immediately needed for test_calltips, that is another issue.) -- assignee: terry.reedy components: IDLE, Tests messages: 165825 nosy: serwy, terry.reedy priority: normal severity: normal stage: test needed status: open title: Create a unittest framework for IDLE type: enhancement versions: Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15392 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
