This is a friendlier version of Kent Becks "Test && Commit || Revert" https://medium.com/@kentbeck_7670/test-commit-revert-870bbd756864 that integrates well in your workflow (assuming jest+git).
A jest watch plugin to learn disciplined TDD, it continously runs your tests, it commits when passed. On a failure, it reverts everything except for your test files. That last part is important to me, as "Red" is the first step in "Red-Green-Refactor".
- To install in your project:
npm install --save-dev tcr-jest-watch-plugin
- Add to your
jest.config.js:
watchPlugins: ['tcr-jest-watch-plugin'],
- Run with
jest --watchAll
Note: Before watching you might want to create an empty commit, as the plugin will amend all your changes to the last commit. For example:
git commit -m "feat: building my new feature" --alow-empty
