Espresso test, click on Chip view not working
I have a ChipGroup containing some Chip views that when checked, display some TextViews and SeekBars. I am trying to test this using Espresso and I am getting odd results.
Because the following test failed: (Test1)
@Test
fun whenEuropeChipIsSelected_DisplaySeekBarsAndTextViews() {
launchFragmentInContainer<GameConfigSurvivalFragment>()
onView(withId(R.id.europeSurvChip)).perform(click())
onView(withId(R.id.countriesNumberSeekBar)).check(matches(isDisplayed()))
onView(withId(R.id.selectCountriesNumberTv)).check(matches(isDisplayed()))
onView(withId(R.id.selectedCountriesTV)).check(matches(isDisplayed()))
onView(withId(R.id.timeLimitSeekBar)).check(matches(isDisplayed()))
onView(withId(R.id.timeLimitTv)).check(matches(isDisplayed()))
onView(withId(R.id.selectTimeLimitTv)).check(matches(withEffectiveVisibility(Visibility.VISIBLE)))
}
I created the following simple test to see what is happening: (Test2) which is also failing. (See stack trace below)
@Test
fun whenEuropeChipIsClicked_CheckIsSelected() {
launchFragmentInContainer<GameConfigSurvivalFragment>()
onView(withId(R.id.europeSurvChip)).perform(click())
onView(withId(R.id.europeSurvChip)).check(matches(isChecked()))
}
Some of my production code for this feature looks like this and I inserted some logs to see what is the state of the chip when I click on the chip:
binding.europeSurvChip.setOnCheckedChangeListener { isChecked ->
if (isChecked) {
counter.value = counter.value!!.plus(Europe.totalCountries)
continentsList.add(Europe)
Log.d("ChipSelected", "EuropeChipSelected: isChecked: ${europeSurvChip.isChecked}")
} else {
counter.value = counter.value!!.minus(Europe.totalCountries)
continentsList.remove(Europe)
Log.d("ChipSelected", "EuropeChipSelected: isChecked: ${europeSurvChip.isChecked}")
}
}
While testing the selection of the Chip manually on the emulator I achieve the intended result, and I can see on the log that the Chip is checked and unchecked. However, the Espresso tests I created never pass. Manually testing everything works as expected and the Seekbars and TextViews are displayed as well as the Chip button being checked.
I disabled animations as other questions suggested it to people suffering from Espresso's click() method not working properly.
Any idea what am I doing wrong? (everything is happening in the main thread)
Ideas I feel not confident about:
Does it have to do with the fact that I am using observers?
Is Espresso's
click()method not working onChipviews? (hard to believe)

Fixed it by making the Chip clickable and checkable in the XML file.
I am guessing it was made clickable and checkable programmatically somewhere in the code.
