As part of porting our browser tests to Cypress, we first need to create an initial setup.
To check that it works, we can port the simple “hello world” test spec that was initially added to set up Selenium (T189677).
EntitySchema has a working Cypress setup - see T333427 for the change that introduced that.
Acceptance criteria:
- developers can run Cypress locally
- at least one Cypress test (even if it doesn’t do much) runs in CI, and blocks merges if it fails
