android - 在浓缩咖啡测试中瞄准 NachoChip

Question

我正在开发一个使用NachoChips的应用程序，并且我正在努力以他们为目标，下拉他们实施的建议。测试包含它们的片段时我想要发生的是：
某些文本输入到字段
下拉出现
单击下拉。
我曾尝试使用 espresso 录制来重新创建它，但是将这样做的代码移植到实际测试中证明是徒劳的，只给出了 androidx.test.espresso.NoMatchingViewException。以下是录音中的完整代码：

ViewInteraction appCompatEditText = onView(
                allOf(withId(R.id.editText_username_input),
                        childAtPosition(
                                childAtPosition(
                                        withClassName(is("android.widget.RelativeLayout")),
                                        1),
                                3),

        appCompatEditText.perform(replaceText("[e-mail]"), closeSoftKeyboard());

如您所见，在测试中，我尝试从 FragmentScenario 开始，但录制从我的应用程序的登录页面开始（必要时），这可能是问题的原因。
我也尝试使用 android studio 的 LiveLayout 功能，但任何尝试在下拉建议出现后实际选择它只会抓住下拉列表后面的元素。
有想法该怎么解决这个吗？
