Guys, super quick question. Any idea why this test is not passing? I would expect firstOrError to throw error if subject has no values.

@Test
    fun `assert tha behaviour subject behaves like i would expect to behave`() {
        BehaviorSubject.create<Boolean>()
                .firstOrError()
                .test()
                .assertComplete()
    }

is it failing on assertComplete()? doesn’t look like that subject would ever complete

[filipradon]

It should be error actually, but the issue is with firstOrError -> i have troubles with understanding why it’s NOT throwing an error when there are no items

[starke]

the subject has to complete first since firstOrError just creates a single that’s waiting for a terminal event like onNext, onComplete, onError

[filipradon]

Any idea how I can map that behaviour subject easily to get expected (expected for me) result which is error when there are no elements?

[starke]

call onComplete
