• assert_chaos_handled

  Injects a chaos HTTP status into all matching requests, then returns a structured verdict: did the app show a fallback UI, were there unhandled JS exceptions, and did it survive? Use to answer: is the app chaos-resilient — does it show a recovery UI without throwing exceptions?

• block_resources

  Blocks requests to specified URL patterns — useful for simulating third-party outages (analytics, CDNs, tracking). Use to answer: does the app still load and function if Google Analytics or a CDN is down?

• inject_latency

  Adds artificial delay to requests matching a URL pattern, simulating slow networks or overloaded APIs. Use to answer: does the app show loading states when the API takes 3 seconds? Does it time out gracefully?

• inject_response_corruption

  Intercepts requests matching a URL pattern and returns a malformed or corrupted response, simulating partial network failures at the protocol level. Use to answer: does the app handle malformed JSON, content-length lies, or truncated payloads without crashing?

• simulate_api_failure

  Intercepts API requests matching a URL pattern and makes them return an error status code. Navigates to the page and checks if a fallback UI element appears. Use to answer: does the app show a proper error state when the payment API returns 503?

• simulate_network_drop

  Aborts requests matching a pattern after a delay, simulating a mid-flight connection drop. Use to answer: what happens if the network drops after the order request is sent but before the response arrives?

• simulate_stateful_failure

  Intercepts requests matching a URL pattern and fails the first N requests with an error status, then lets subsequent requests succeed. Simulates transient failures and tests retry/recovery logic. Use to answer: does the app retry after a 503 and recover when the service comes back?

• trigger_system_network_error

  Aborts requests matching a URL pattern with a system-level network error code, simulating OS-level failures like unreachable hosts or access denied. Use to answer: does the app recover when the DNS resolution fails or the OS rejects a connection?
