Description:
pytestpitch 1.0.5
pytest_pitch
pytest_pitch runs tests in an order such that coverage increases as fast as possible. Typically 99% of the total coverage is achieved in 10% of the test session time.
use as pytest plugin for faster coverage increase
First create persistent time-coverage record via pytest-donde
python -m pytest [YOUR SESSION ARGS] --donde=/path/to/src
where /path/to/src is the code region to cover.
Then pass the record file to the plugin via
python -m pytest [YOUR SESSION ARGS] --pitch
If You change your test definitions or test selection [YOUR SESSION ARGS]
in step 2 without updating the record:
tests which are unknown to step 1 (e.g. newly defined tests, less strict test selection)
will be put to the start of the execution order
tests which are known to step 1 but missing in step 2 (e.g. removed tests, stricter test selection) will just be filtered out. Any selection mechanisms should not conflict with the reordering.
use in your script
See this script as a demo which was used to create the image shown above.
