 To build the TypeScript code, use one of:
 
 ```sh
+cd api
 npm run build
 npm run build:watch
 ```
 
-### Test
-
-To run all the tests, use:
-
-```sh
-npm run test -- --deploy path/to/wonderland/deploy
-```
-
-It's required to pass the Wonderland Editor deploy folder as a CLI argument using
-the `--deploy` argument.
-
-If no such flag is passed, the test framework will assume
-that the deploy folder is located in `../../deploy`.
-
-#### Test Projects
-
-Some tests use projects as inputs, e.g.,
-* `animation.tests.ts`
-* `component.tests.ts`
-* `mesh.tests.ts`
-* `scene.test.ts`
-* `scene-gltf.test.ts`
-
-Those projects are required to be built before the tests can run. You can build all projects using:
-
-```sh
-npm run test:build -- path/to/wonderlandengine
-```
-
-Each projects `deploy/` will be copied into `test/resources/projects`.
-
-#### Test File
-
-To run the tests in a file, use:
-
-```sh
- npm run test -- [PATH] --deploy path/to/wonderland/deploy
-```
-
-Example with the component file:
-
-```sh
-npm run test -- ./test/component.test.ts --deploy path/to/wonderland/deploy
-```
-
-#### Watch
-
-It's possible to watch one/multiple test(s) using `--watch`:
-
-```sh
-npm run test -- --deploy path/to/wonderland/deploy --watch
-```
-
-#### Grep
-
-The runner uses Mocha, which supports filtering tests using [regexp](https://mochajs.org/api/mocha#grep).
-
-You can provide a regexp using `--grep` or `-g`:
-
-```sh
-npm run test -- -g 'MeshComponent'
-```
-
-The `grep` flag can be mixed with the positional file argument:
-
-```sh
-npm run test -- ./test/component.test.ts -g 'MeshComponent'
-```
+### End-to-End Test
 
-This command will only run the tests matching the "MeshComponent" string in the `test/component.test.ts` file.
+For information about how to run the end-to-end tests, have a look at the
+`packages/test-e2e` [README.md](./test/README.md)
