Watch mode

bunpy test --watch

Watch mode monitors the source files of every test file and re-runs the affected tests on each save. Useful during TDD cycles.

Behaviour

• On startup, all tests run once.
• When a test file changes, only that file’s tests re-run.
• When a non-test source file changes, all tests that import it (directly or transitively) re-run.
• The terminal clears and shows fresh results on each re-run.
• A summary line shows total pass / fail counts and elapsed time.

Filter in watch mode

Only tests whose name contains “auth” are collected and re-run.
