Hi All,
I'm pleased to announce the first advertised release of TestFixtures.
This is a collection of helpers and mock objects that are useful when
writing unit tests or doc tests.
The modules currently included are:
*Comparison*
This class lets you instantiate placeholders that can be used to
compared expected results with actual results where objects in the
actual results do not support useful comparison. The comparision can be
based just on the type of the object or on a partial set of the object's
attributes, both of which are particularly handy when comparing
sequences returned from tested code.
*compare*
A replacement for assertEquals and the failUnless(x() is True) pattern.
Gives more useful differences when the arguments aren't the same,
particularly for sequences and long strings.
*diff*
This function will compare two strings and give a unified diff of their
comparison. Handy as a third parameter to unittest.TestCase.assertEquals.
*generator*
This function will return a generator that yields the arguments it was
called with when the generator is iterated over.
*LogCapture*
This helper allows you to capture log messages for specified loggers in
doctests.
*log_capture*
This decorator allows you to capture log messages for specified loggers
for the duration of unittest methods.
*replace*
This decorator enables you to replace objects such as classes and
functions for the duration of a unittest method. The replacements are
removed regardless of what happens during the test.
*Replacer*
This helper enables you to replace objects such as classes and functions
from within doctests and then restore the originals once testing is
completed.
*should_raise*
This is a better version of assertRaises that lets you check the
exception raised is not only of the correct type but also has the
correct parameters.
*TempDirectory*
This helper will create a temporary directory for you using mkdtemp and
provides a handy class method for cleaning all of these up.
*tempdir*
This decorator will create a temporary directory for the duration of the
unit test and clear it up no matter the outcome of the test.
*test_date*
This is a handy class factory that returns datetime.date replacements
that have a today method that gives repeatable, specifiable, testable dates.
*test_datetime*
This is a handy class factory that returns datetime.datetime
replacements that have a now method that gives repeatable, specifiable,
testable datetimes.
*test_time*
This is a handy replacement for time.time that gives repeatable,
specifiable, testable times.
*wrap*
This is a generic decorator for wrapping method and function calls with
a try-finally and having code executed before the try and as part of the
finally.
