PYTEST-WATCHER(1)

NAME

pytest-watcher - Automatically rerun Python tests on code changes

DESCRIPTION
pytest-watcher is a tool to automatically rerun tests (using pytest by default) whenever your code changes. It is designed to be simple, effective, and compatible with most Python projects out of the box. The watcher listens for file creation, deletion, modification, and move events. Upon detecting changes, it re-runs your tests with the most recent code state. Unlike tools that rely on polling, pytest-watcher uses the native system file monitoring API (where supported) to efficiently detect file system events. For a list of supported platforms and caveats, see the watchdog documentation in the LINKS section. pytest-watcher offers an interactive mode with handy keyboard shortcuts.

USAGE
Specify the path that you want to watch:

        ptw .
    or

        ptw /home/repos/project
    pytest-watcher passes all arguments following <path> to the test runner (defaulting to pytest), except for its own reserved options (see OPTIONS). For example:

        ptw . -x --lf --nf
    This will invoke the test runner as:

        pytest -x --lf --nf

OPTIONS
The following options are reserved for pytest-watcher and will not be passed to the test runner:

--runner
    Specify an alternative test runner.

--patterns
    Specify file patterns to watch.

--ignore-patterns
    Specify file patterns to ignore.

--now
    Run tests immediately after starting the watcher.

--delay
    Specify the delay before running tests.

--clear
    Clear the terminal screen before each test run.
