Hi all,
I read the python unittest document, but I still have some problems. Could I
ask some questions? Because I don't know how to create my unittest scripts for
my directory structure.
My directory structure looks like this:
project_0001/
|___plugin_0001/
| |___test/
| | |___testcase_0001/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___testcase_0002/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___testcase_0003/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___ __init__.py
| | |___ test.py
| |
| |_____ __init__.py
| |_____ test.py
|
|___plugin_0002/
| |___test/
| | |___testcase_0001/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___testcase_0002/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___testcase_0003/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___ __init__.py
| | |___ test.py
| |
| |_____ __init__.py
| |_____ test.py
|
|___plugin_0003/
| |___test/
| | |___testcase_0001/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___testcase_0002/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___testcase_0003/
| | | |___ __init__.py
| | | |___ test.py
| | |
| | |___ __init__.py
| | |___ test.py
| |
| |_____ __init__.py
| |_____ test.py
|
|____ __init__.py
|____ test.py
My requirements and my problems:
I tend to write only one testcase in each testcase
diretory(e.g.project_*/plugin_*/test/testcase_*/test.py)
For example,
##### project_0001\plugin_0001\test\test_0001\test.py #####
import unittest
class TestStringMethods(unittest.TestCase):
def setUp(self):
print('\nthis is test_0001.TestStringMethods.setUp');
def tearDown(self):
print('\nthis is test_0001.TestStringMethods.tearDown');
def test_upper(self):
self.assertEqual('foo'.upper(), 'FOO')
#print('this file is: '+__file__);
print('\nthis is test_0001.TestStringMethods.test_upper');
def test_isupper(self):
self.assertTrue('FOO'.isupper())
self.assertFalse('Foo'.isupper())
print('\nthis is test_0001.TestStringMethods.test_isupper');
def runTest(self):
print('\nthis is test_0001.TestStringMethods.runTest');
if __name__ == '__main__':
# unittest.main()
suite = unittest.TestLoader().loadTestsFromTestCase(TestStringMethods)
unittest.TextTestRunner(verbosity=2).run(suite)
###########################################################
Then I run the test
\>cd project_0001\plugin_0001\test
\>python -m unittest discover
And here is the log:
this is test_0001.TestStringMethods.setUp
this is test_0001.TestStringMethods.test_isupper
this is test_0001.TestStringMethods.tearDown
.
this is test_0001.TestStringMethods.setUp
this is test_0001.TestStringMethods.test_upper
this is test_0001.TestStringMethods.tearDown
.this is test_0002.TestStringMethods.test_A
.this is test_0002.TestStringMethods.test_B
.this is test_0003.TestStringMethods.test_isupper
.this file is: \project_0001\plugin_0001\test\test_0003\test.pyc
this is test_0003.TestStringMethods.test_upper
.
----------------------------------------------------------------------
Ran 6 tests in 0.000s
OK
Question 1:
why test_0001.TestStringMethods.runTest() is not called? how to invoke
runTest()?
Should I write my test code in test_0001.TestStringMethods.test_*() or
test_0001.TestStringMethods.runTest()?
Which one is better?
Question 2:
How to do 'python -m unittest discover' in python script? I create my test
script but failed.
Here is my steps:
First, I write my script project_0001\plugin_0001\test/test.py
##### project_0001\plugin_0001\test/test.py #####
import os
import sys
import unittest
def main ():
print('__file__='+__file__);
start_dir = os.path.dirname(os. path.abspath(__file__));
start_dir = start_dir.replace('\\', '/')
print('start_dir='+start_dir);
unittest.defaultTestLoader.discover(start_dir, pattern='test_*')
if __name__ == '__main__':
main ()
#####################################################
Second, I run the test
\>cd project_0001\plugin_0001\test
\>python ./test.py
And here is the log:
__file__=./test.py
start_dir=D:/dev/mymagicbox/automation/test/project_0001/plugin_0001/test
It shows my problem, all the testcase_*/test.py are not run. Why? how to solve
this problem?
Question 3:
Sometimes, I will take project_0001\plugin_0001\test as the start_dir of my
unittest. By default, it should recursively run the unittest in the following
sub-directories:
project_0001\plugin_0001\test\testcase_0001\,
project_0001\plugin_0001\test\testcase_0002\,
project_0001\plugin_0001\test\testcase_0003\,
But, sometimes, I tend to skip testcase_0002 and only do unittest for
testcase_0001 and testcase_0003.
How to deal with this problem?
Question 4:
Sometimes, I will take project_0001\ as the start_dir of my unittest. By
default, it should recursively run the unittest for the following
sub-directories :
project_0001\plugin_0001\test\testcase_0001\,
project_0001\plugin_0001\test\testcase_0002\,
project_0001\plugin_0001\test\testcase_0003\,
project_0001\plugin_0002\test\testcase_0001\,
project_0001\plugin_0002\test\testcase_0002\,
project_0001\plugin_0002\test\testcase_0003\,
project_0001\plugin_0003\test\testcase_0001\,
project_0001\plugin_0003\test\testcase_0002\,
project_0001\plugin_0003\test\testcase_0003\,
But, sometimes, I tend to skip plugin_0002 and only recursively do unittest for
plugin_0001 and plugin_0003. It means doing the following unittests:
project_0001\plugin_0001\test\testcase_0001\,
project_0001\plugin_0001\test\testcase_0002\,
project_0001\plugin_0001\test\testcase_0003\,
project_0001\plugin_0003\test\testcase_0001\,
project_0001\plugin_0003\test\testcase_0002\,
project_0001\plugin_0003\test\testcase_0003\,
How to deal with this problem?
Question 5:
If it would be possible, I tend to invoke these unittest in Maya which is a DCC
software(www.autodesk.com/products/maya/overview). Maya has a python script
editor, it can run the unittest by invoking execfile(start_dir+'/test.py'), but
it complains __file__ is not defined. What should I do? I mean, should I try to
avoid using __file__ as possible as I can in my unittest scripts? or should I
create my global variable 'g__file__' to replace __file__, and how to do this?
Finally, any suggestion is appreciated, and thank you in advance.
Cheers
yao
