我开始使用浓缩咖啡为我的应用程序编写仪器测试，但是我遇到了问题。
尝试单击我的注册按钮
时在测试中onData(withId(R.id.signUpButton)).perform(click());
我得到错误
android.support.test.espresso.PerformException: Error performing 'load adapter data' on view 'is assignable from class: class android.widget.AdapterView'.
我从onView更改为onData，就像使用onView时，我正在接收错误消息
android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: uk.co.vouchercodes.android.beta:id/signUpButton
If the target view is not part of the view hierarchy, you may need to use Espresso.onData to load it from one of the following AdapterViews:android.widget.GridView{5c810ee VFED..C.. ........ 0,0-1080,1376 #7f1001f0 app:id/onboardingMerchantGridView}
有人遇到类似问题吗？关于这个问题的最好方法是什么？
谢谢 xml

您应该使用onview方法。您的问题是使用错误的ID。您定义了名为Signbutton的按钮，但是您使用的按钮称为IngiupButton，因此您会遇到错误。
