To make a test fail, pytest utilizes the python built-in assert keyword. Minimizing output. See getting-started for more examples. This plugin converts that rewritten AST back to Python source, and displays it. The pytest framework makes it easy to write small tests, yet scales to support complex functional testing - pytest-dev/pytest. But see how that assert is outside the with block? pytest rewrites test modules on import by using an import Pytest. pytest will write back the rewritten modules to disk for caching.

If this assertion fails Thanks to the maintainers of ICDiff and also pprintpp! pytest-twisted pauses and resumes the reactor using a greenlet which defeats the entire purpose of using a reactor/event loop for explicit non-blocking IO. Due to pytest's detailed assertion introspection, only plain assert statements are used. The main attributes of interest are Once you've installed it, pytest will produce nice colourised diffs for any assert ==: Issues and PRs welcome. pytest has rich support for providing context-sensitive information What would you like to do? like documenting unfixed bugs (where the test describes what "should" happen) Sign up Why GitHub? This is where pytest-github can be of use. Pytest will collect these functions and run them for you. For example, you can write the following: # content of test_assert1.py def f (): return 3 def test_function (): assert f == 4. to assert that your function returns a certain value. pytest-asyncio is an Apache2 licensed library, written in Python, for testing asyncio code with pytest. runpytest result.

I really liked the idea of utilizing fixtures, automatically running my test functions, and utilizing a bit of the pytest reporting capabilities.
