+
+# Integration Tests
+
+Each directory in the fixtures directory represents one testing scenario, with a corresponding test file for each bundler we currently support.
+When `pnpm run test:e2e` is ran, we run jest, which will pick up all \*.test.ts files.
+
+In the `test-api` directory is a simple API that we use to create more realistic testing scenarios for each bundler.
+
+In the `test-apps` directory are a set of apps that we use to test the integration with each bundler.
