Backend Tests

Running Tests

cd backend
go test ./...

Test Database

Tests use an in-memory SQLite database that is auto-migrated before each test. No external dependencies required.

Writing Tests

Use the test helpers in the _test files alongside each package. Set up a test DB with database.NewTestDB() (or equivalent), create a Gin test context, and call controller functions directly. Assert on the httptest.ResponseRecorder.

Frontend Tests

There are no isolated frontend tests with yarn test, since this requires code/logic duplication for mocking. Instead Playwright is used to run integrated E2E tests.

Setup

cd frontend
yarn playwright install  # install browsers (first time only)

The E2E tests expect the full application running on http://localhost:7300. global-setup.ts seeds a test user before the suite runs.

Running E2E Tests

yarn test:e2e           # headless
yarn test:e2e:headed    # with browser visible
yarn test:e2e:ui        # Playwright UI mode
yarn test:e2e:debug     # debug mode

Writing E2E Tests

Tests live in frontend/e2e/. Use the shared fixtures from fixtures.ts for login/logout helpers and the TEST_USER credentials from global-setup.ts. Group tests with test.describe and keep each test independent.
