To simulate user-event clicks and typing in React IT Gherkin tests, use the command handler to apply userEvent actions like click, type, and submit during the When stage. This keeps UI mutations deterministic and separated from Then stage assertions.

The best way to structure mutations and assertions in Gherkin it-tests is to isolate UI mutations in the command handler using user-event, while leaving all state validations and assertions to the Then stage to enforce test determinism.

Yes, user-event works with React Testing Library for form submission in Gherkin scenarios by using the command handler to simulate submit actions. This ensures form interactions are treated as deterministic mutations across UI components.

You need to use a command handler for UI interactions in it-tests whenever scenarios involve state changes like clicks, typing, or form submissions. It enforces the use of @testing-library/user-event to keep interaction steps deterministic.

You should separate command steps from assertions in React Gherkin tests to keep mutation logic isolated from validation. Using the command handler for user-event actions prevents side effects from leaking into the Then stage, maintaining deterministic test behavior.
