I do have several small modules where the tests are inside them and py.test
or nose
does not look for them because they do not contain test
in their filename.
How can I convince py.test
or nose
to look for tests inside all python files, recursively - '''including the ones that do not have test
in their filenames'''?
Inside the source files I do keep the standard naming convention: class testSomeName
with methods def test_some_name
.
If this is not possible, what other solution can I use to obtain the same result.
I do not want to manually create a list of all files containing the test, I want a solution that supports discovery.
Running pytestWe can run a specific test file by giving its name as an argument. A specific function can be run by providing its name after the :: characters. Markers can be used to group tests. A marked grouped of tests is then run with pytest -m .
pytest has basic support for running tests written for nose.
Run all Python tests in a directoryFrom the context menu, select the corresponding run command. If the directory contains tests that belong to the different testing frameworks, select the configuration to be used. For example, select Run 'All tests in: <directory name>' Run pytest in <directory name>'.
You can also have a look at Nose which will discover tests without having to use a fixed file name convention.
You can bypass the regexp used to filter files in nose with the following code.
Create a python module (i.e. my_nosetests.py
)
import nose
from nose.plugins.base import Plugin
class ExtensionPlugin(Plugin):
name = "ExtensionPlugin"
def options(self, parser, env):
Plugin.options(self,parser,env)
def configure(self, options, config):
Plugin.configure(self, options, config)
self.enabled = True
def wantFile(self, file):
return file.endswith('.py')
def wantDirectory(self,directory):
return True
def wantModule(self,file):
return True
if __name__ == '__main__':
includeDirs = ["-w", ".", ".."]
nose.main(addplugins=[ExtensionPlugin()], argv=sys.argv.extend(includeDirs))
Now run my_nosetests.py
as if you were running nosetests
and you should have your tests running. Be aware that you are in fact loading all modules and searching for tests in them. Beware of any side effect of module loading.
