Testing Forms — Simulating Input, Validations, and Submissions

Verify that your reactive forms validate correctly, show the right error messages at the right time, and call the right service methods on submission — without a browser and without brittle CSS selectors. After this lesson you'll simulate user input with dispatchEvent, test validation state transitions, and assert on form submission behaviour with spy objects.
