Test failing for MainViewModelTest.kt #62

Open svvashishtha opened 4 years ago

svvashishtha commented 4 years ago

While running the first test for MainViewModelTest.kt my test failed every time until I modified the code from codelab myself. code provided in codelab 

@Test
fun whenMainClicked_updatesTaps() {
   subject.onMainViewClicked()
   Truth.assertThat(subject.taps.getValueForTest()).isEqualTo("0 taps")
   coroutineScope.advanceTimeBy(1000)
   Truth.assertThat(subject.taps.getValueForTest()).isEqualTo("1 taps")
}

Code after I modified it 

 @Test
    fun whenMainClicked_updatesTaps() {
        Truth.assertThat(subject.taps.getValueForTest()).isEqualTo("0 taps")
        subject.onMainViewClicked()
        coroutineScope.advanceTimeBy(1000)
        Truth.assertThat(subject.taps.getValueForTest()).isEqualTo("1 taps")
    }

when the test failed, I always get this result 

expected: 0 taps
but was : 1 taps
Expected :0 taps
Actual   :1 taps
