RxJava 2 overriding IO scheduler in unit test

Question

I\'m trying to test the following RxKotlin/RxJava 2 code:

validate(data)
    .subscribeOn(Schedulers.io())
    .observeO         


        

Answer 1

This is the exact syntax that worked for me:

RxJavaPlugins.setIoSchedulerHandler(scheduler -> Schedulers.trampoline())
