Just Another Marble Monday – Unit Testing NGRX/RxJS w/Marbles

on YouTube ↗44m

" summary

Concrete instructions for testing NGRX/RxJS with marbles include using Jasmine marbles to write hot and cold observables, injecting a test scheduler via getTestScheduler to control async timing, and asserting specific delays like the 210 frame roundtrip and the 30-frame debounce behavior. Examples include effect tests for load dancers and a battle feature, handling success and thrown errors, and building an 80s dance-off in a Tour of Heroes clone that actually runs and tests end to end.
