Pytest test running.
|
|
|
|
This module implements the ``test()`` function for NumPy modules. The usual
|
|
boiler plate for doing that is to put the following in the module
|
|
``__init__.py`` file::
|
|
|
|
from pywt._pytesttester import PytestTester
|
|
test = PytestTester(__name__).test
|
|
del PytestTester
|
|
|
|
|
|
Warnings filtering and other runtime settings should be dealt with in the
|
|
``pytest.ini`` file in the pywt repo root. The behavior of the test depends on
|
|
whether or not that file is found as follows:
|
|
|
|
* ``pytest.ini`` is present (develop mode)
|
|
All warnings except those explicily filtered out are raised as error.
|
|
* ``pytest.ini`` is absent (release mode)
|
|
DeprecationWarnings and PendingDeprecationWarnings are ignored, other
|
|
warnings are passed through.
|
|
|
|
In practice, tests run from the PyWavelets repo are run in develop mode. That
|
|
includes the standard ``python runtests.py`` invocation.

Pytest test runner.
|
|
|
|
This class is made available in ``pywt.testing``, and a test function
|
|
is typically added to a package's __init__.py like so::
|
|
|
|
from pywt.testing import PytestTester
|
|
test = PytestTester(__name__).test
|
|
del PytestTester
|
|
|
|
Calling this test function finds and runs all tests associated with the
|
|
module and all its sub-modules.
|
|
|
|
Attributes
|
|
----------
|
|
module_name : str
|
|
Full path to the package to test.
|
|
|
|
Parameters
|
|
----------
|
|
module_name : module name
|
|
The name of the module to test.

|
|
Run tests for module using pytest.
|
|
|
|
Parameters
|
|
----------
|
|
label : {'fast', 'full'}, optional
|
|
Identifies the tests to run. When set to 'fast', tests decorated
|
|
with `pytest.mark.slow` are skipped, when 'full', the slow marker
|
|
is ignored.
|
|
verbose : int, optional
|
|
Verbosity value for test outputs, in the range 1-3. Default is 1.
|
|
extra_argv : list, optional
|
|
List with any extra arguments to pass to pytests.
|
|
doctests : bool, optional
|
|
.. note:: Not supported
|
|
coverage : bool, optional
|
|
If True, report coverage of NumPy code. Default is False.
|
|
Requires installation of (pip) pytest-cov.
|
|
durations : int, optional
|
|
If < 0, do nothing, If 0, report time of all tests, if > 0,
|
|
report the time of the slowest `timer` tests. Default is -1.
|
|
tests : test or list of tests
|
|
Tests to be executed with pytest '--pyargs'
