In this boilerplate, Jest is used for unit tests and Playwright for integration and end-to-end tests.
Write unit tests with Jest
To get started with writing unit tests, check out this tutorial from Jest: https://jestjs.io/docs/tutorial-react.
You can also find example tests in the __test__ directory. To add more tests, create a new file in the __test__ directory and add your test code.
To run tests locally, run the following command:
npm run test:ci
Write integration tests with Playwright
To get started with writing integration tests, check out this documentation from Playwright: https://playwright.dev/docs/writing-tests.
You can also find example end-to-end tests in the e2e directory. To add more tests, create a new file in the e2e directory and add your test code.
To run tests locally, run the following command:
npm run test:e2e
