Tests are split by categories. Default categories are:

These tests are running in different pools with a single config file. If you just need to test a function call, you can place your test here.

This is the only test category that doesn't start new Vitest instance for every test.

Place your test here if you are testing a config opton.

If you are testing a complex interaction, place your tests here.

If you are testing browser mode, add your tests here.

These are e2e tests for UI package. We are using playwright to test it.

Place your tests here if you are testing Vitest behaviour when file is created/updated/removed.

All other categories just group tests by type.
