A plugin that selects only tests with changes in execution path
A plugin that executes only the tests with changes in execution path
This Pytest plugin was generated with Cookiecutter along with @hackebrot’s Cookiecutter-pytest-plugin template.
You can install “pytest-skipper” via pip from PyPI:
$ pip install pytest-skipper
Capture execution trace
$ py.test –trace
This will run the full test suite and record coverage scopes (= name of executed functions) for each test. The scopes are stored in sqlite database skipper.db. The git repo may not have any uncommitted changes when execution trace is recorded.
Execute only tests with changes in execution path
$ py.test –skipper
This command compares your projects git repo state against traces in scope database and selects the execution trace with least code changes. After this the program calculates all scopes with changes and uses those to select only the tests that have changes in their execution path.
Update execution trace while running few tests
$ py.test –skipper –trace
You can use --trace and --skipper arguments at the same time to update the previous execution trace to the latest version without re-running all the tests. Execution traces are stored after each test case, so it is possible to terminate this command and continue it later.
List tests with changes
$ py.test –dry-run-skipper
Same as --skipper, but instead of running the tests, only outputs them. Useful to see what tests need to be updated after code change.
Contributions are very welcome. Tests can be run with tox, please ensure the coverage at least stays the same before you submit a pull request.
