End to end testing

Complex components require integration tests. We use Cypress as an end to end test framework to test components hierarchies and integrations with dependencies.

Adding new tests

Tests should be added in the cypress/integration folder, only when testing a component in isolation through unit tests is not enough to provide thorough test coverage.

Running Cypress tests

Tests can be ran locally with the following command, which open the cypress dashboard:

yarn run cypress open

To run tests as a headless browser, run the following command:

yarn test:integration

In both cases, the server needs to be running.
