Description

Just trying out AVA instead of Jest in a new monorepo project. I am configuring testing to be run as a pre-commit hook using husky and lint-staged.

I've run into a problem getting the appropriate tests run by ava during a commit. Previously, I would use lint-staged which would pass the changed files as arguments to jest and using the --findRelatedTests flag, jest would run only the tests that covered those files.

Trying to do something similar with ava has left me at a dead-end. If I try to use lint-staged to run ava, it passes a list of changed files and ava tries to run them as tests which fails. The alternative is simply to run the entire test suite, which will become inefficient as the project grows.

Any thing I'm missing, or thoughts on how to run appropriate ava tests as part of a pre-commit process?

Research direction
Investigate how AVA currently discovers and runs test files. Study the existing codebase, particularly the test selection logic. Review the submitted PR #3443 referenced in the IssueHunt summary for a potential approach. Consider how other test runners like Jest implement related test selection using dependency analysis. The goal is to implement a similar feature in AVA.
