Util Asynctestcase

Adds support for test cases which need to be run in an event loop.

Also contains a class integration tests can derive from. The integration tests can declare which of the plugins (that are a part of the main repo) they require to run. The test will be skipped if the plugin isn’t installed in development mode.

To install all plugins in development mode $ dffml service dev install

Add the -user flag to install to ~/.local

class dffml.util.asynctestcase.AsyncTestCase(methodName='runTest')

Runs any test_ methods as coroutines in the default event loop.

Examples

>>> import asyncio
>>> from dffml import AsyncTestCase
>>>
>>> class AsyncTestCase(AsyncTestCase):
...     async def test_sleep(self):
...         await asyncio.sleep(1)

async_wrapper(coro)

Returns a function which calls the test_ function which calls loop.run_until_complete to return the result of the test.

run(result=None)

Convert all test_ methods via async_wrapper so that they are run in the event loop.

async setUp()

Hook method for setting up the test fixture before exercising it.

async tearDown()

Hook method for deconstructing the test fixture after testing it.

dffml.util.asynctestcase.non_existant_tempfile()

Yield the filename of a non-existant file within a temporary directory

dffml.util.asynctestcase.relative_chdir(*args)

Change directory to a location relative to the location of this file.

dffml.util.asynctestcase.relative_path(*args)

Returns a pathlib.Path object with the path relative to this file.
