Testing

Test Organization

Parallel Tests (can run simultaneously):

Client tests
Package tests
E2E tests (isolated databases)

Sequential Tests (shared resources):

Server tests (shared database)
CKEditor plugin tests

Test Frameworks

Vitest - Unit and integration tests
Playwright - E2E tests
Happy-DOM - DOM testing environment

Running tests

At project root:

pnpm test:all          # All tests
pnpm test:parallel     # Fast parallel tests
pnpm test:sequential   # Sequential tests only

Unit testing and integration testing

Using vitest, there are some unit and integration tests done for both the client and the server.

These tests can be found by looking for the corresponding .spec.ts in the same directory as the source file.

To run the server-side tests:

npm run server:test

To view the code coverage for the server:

npm run server:coverage

Afterwards, a friendly HTML report can be found in /coverage/index.html.

To run the client-side tests:

npm run client:test

To view the code coverage for the client:

npm run client:coverage

Afterwards, a friendly HTML report can be found in /src/public/app/coverage/index.html.

To run both client and server-side tests:

npm run test

Note that some integration tests rely on an in-memory database in order to function.

REST API testing for the server

API tests are handled via vitest and supertest to initialize the Express server and run assertions without having to make actual requests to the server.

An important aspect is that we have access to the Express app which allows for interesting assertions such as checking the state of the server, registering debug middleware and so on.

One example is src/share/routes.spec.ts, or for the ETAPI in apps/server/spec/etapi.

These integration tests are run alongside unit tests.
