Introduction to Marble Testing Rx (Web, iOS, Android)

on YouTube ↗16m

" summary

Shows how to use marble testing with Rx (Web, iOS, Android) to drive and assert time-dependent reactive flows inside a ViewModel without full end-to-end runs. Uses a virtual-time scheduler and marble strings mapped to values to simulate debounce (500 ms), service response timing, and switchMap cancellation in a sample weather app so tests can verify loading/error states and catch race conditions.
