Test Discovery
|
||||
--------------
|
||||
|
||||
.. versionadded:: 2.7
|
||||
|
||||
unittest supports simple test discovery. For a project's tests to be
|
||||
compatible with test discovery they must all be importable from the top level
|
||||
directory of the project; i.e. they must all be in Python packages.
|
||||
|
||||
Test discovery is implemented in :meth:`TestLoader.discover`, but can also be
|
||||
used from the command line. The basic command line usage is::
|
||||
|
||||
cd project_directory
|
||||
python -m unittest discover
|
||||
|
||||
The ``discover`` sub-command has the following options:
|
||||
|
||||
-v, --verbose Verbose output
|
||||
-s directory Directory to start discovery ('.' default)
|
||||
-p pattern Pattern to match test files ('test*.py' default)
|
||||
-t directory Top level directory of project (default to
|
||||
start directory)
|
||||
|
||||
The -s, -p, & -t options can be passsed in as positional arguments. The
|
||||
following two command lines are equivalent::
|
||||
|
||||
python -m unittest -s project_directory -p '*_test.py'
|
||||
python -m unittest project_directory '*_test.py'
|
||||
|
||||
Test modules and packages can customize test loading and discovery by through
|
||||
the `load_tests protocol`_.

load_tests Protocol
|
||||
###################
|
||||
|
||||
Modules or packages can customize how tests are loaded from them during normal
|
||||
test runs or test discovery by implementing a function called ``load_tests``.
|
||||
|
||||
If a test module defines ``load_tests`` it will be called by
|
||||
:meth:`TestLoader.loadTestsFromModule` with the following arguments::
|
||||
|
||||
load_tests(loader, standard_tests, None)
|
||||
|
||||
It should return a :class:`TestSuite`.
|
||||
|
||||
*loader* is the instance of :class:`TestLoader` doing the loading.
|
||||
*standard_tests* are the tests that would be loaded by default from the
|
||||
module. It is common for test modules to only want to add or remove tests
|
||||
from the standard set of tests.
|
||||
The third argument is used when loading packages as part of test discovery.
|
||||
|
||||
A typical ``load_tests`` function that loads tests from a specific set of
|
||||
:class:`TestCase` classes may look like::
|
||||
|
||||
test_cases = (TestCase1, TestCase2, TestCase3)
|
||||
|
||||
def load_tests(loader, tests, pattern):
|
||||
suite = TestSuite()
|
||||
for test_class in test_cases:
|
||||
tests = loader.loadTestsFromTestCase(test_class)
|
||||
suite.addTests(tests)
|
||||
return suite
|
||||
|
||||
If discovery is started, either from the command line or by calling
|
||||
:meth:`TestLoader.discover`, with a pattern that matches a package
|
||||
name then the package :file:`__init__.py` will be checked for ``load_tests``.
|
||||
|
||||
.. note::
|
||||
|
||||
The default pattern is 'test*.py'. This matches all python files
|
||||
that start with 'test' but *won't* match any test directories.
|
||||
|
||||
A pattern like 'test*' will match test packages as well as
|
||||
modules.
|
||||
|
||||
If the package :file:`__init__.py` defines ``load_tests`` then it will be
|
||||
called and discovery not continued into the package. ``load_tests``
|
||||
is called with the following arguments::
|
||||
|
||||
load_tests(loader, standard_tests, pattern)
|
||||
|
||||
This should return a :class:`TestSuite` representing all the tests
|
||||
from the package. (``standard_tests`` will only contain tests
|
||||
collected from :file:`__init__.py`.)
|
||||
|
||||
Because the pattern is passed into ``load_tests`` the package is free to
|
||||
continue (and potentially modify) test discovery. A 'do nothing'
|
||||
``load_tests`` function for a test package would look like::
|
||||
|
||||
def load_tests(loader, standard_tests, pattern):
|
||||
# top level directory cached on loader instance
|
||||
this_dir = os.path.dirname(__file__)
|
||||
package_tests = loader.discover(start_dir=this_dir, pattern=pattern)
|
||||
standard_tests.addTests(package_tests)
|
||||
return standard_tests
