Espresso测试，单击Chip view无效

问题描述 投票：0回答：1

我有一个ChipGroup，其中包含一些Chip视图，选中这些视图时会显示一些TextViews和SeekBars。我正在尝试使用Espresso进行测试，但结果却很奇怪。

因为以下测试失败：（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)))
}

我创建了以下简单测试以查看正在发生的情况：（Test2）也失败了。 （请参阅下面的堆栈跟踪）

@Test
fun whenEuropeChipIsClicked_CheckIsSelected() {
    launchFragmentInContainer<GameConfigSurvivalFragment>()

    onView(withId(R.id.europeSurvChip)).perform(click())

    onView(withId(R.id.europeSurvChip)).check(matches(isChecked()))
}

我的一些此功能的生产代码看起来像这样，当我单击芯片时，我插入了一些日志以查看chip的状态：

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}")
        }
    }

[在仿真器上手动测试Chip的选择时，我达到了预期的结果，并且我在日志中可以看到Chip被选中和未选中。但是，我创建的Espresso测试从未通过。手动测试一切正常，显示Seekbars和TextViews并检查Chip按钮。

我禁用了动画，因为其他问题向Espresso's click()方法无法正常工作的人们建议使用动画。

知道我在做什么错吗？ （一切都在主线程中发生）

想法，我对以下内容没有信心：

  • 这与我使用观察者有关吗？

  • Espresso的click()方法是否不适用于Chip视图？ （难以置信）

通过使Chip在XML文件中可单击和可检查来修复。

我猜它在代码中的某个位置以编程方式使其可单击和可检查。
