trace-error-messages

To trace error messages, you follow a 7-step guide that links the OpenAPI contract, React Query hooks, MSW mock handlers, and UI components to isolate the exact source of the failure. This ensures you assert on the correct cause.

Cypress tests fail when error states are not properly separated between server responses and client-side handling. Tracing errors through the OpenAPI contract and MSW mocks clarifies the expected error shapes and UI rendering.

The best way to debug failing error assertions is tracing the error message from the UI component back through the React Query hooks and MSW mock handlers to the OpenAPI contract. This enforces clear separation of concerns.

Yes, you can use this tracing approach to mock API errors accurately by verifying the error shape in the OpenAPI contract. It isolates server versus client side errors to improve test coverage across end-to-end flows.

Tracing errors through the OpenAPI contract documents the expected error shapes and links server responses to client handling and UI rendering. This directly supports testing form validation and client-side error displays.

An OpenAPI contract is needed to trace client-side errors accurately because it documents the expected error shapes. It provides the baseline to link server responses, MSW mocks, and UI rendering across Cypress tests.
