Android Espresso:如何断言不应显示视图

Question

这似乎是正确的......

onView (withId (R.id.menu_delete)).check (matches (not (isDisplayed ())));

...但它抛出了这个异常:

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: com.just10.android:id/menu_delete
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:com.github.ksoichiro.android.observablescrollview.ObservableListView{3169f0f3 VFED.VC. .F...... 0,0-480,724 #102000a android:id/list}

不应该显示断言视图的最佳方法是什么？

Answer 1

我应该使用的是:

onView(withId(R.id.menu_delete))
  .check(doesNotExist());

这可能特别是视图位于选项菜单中,并且可能在任何给定时间实际存在或不存在,具体取决于onCreateOptionsMenu和onPrepareOptionsMenu中的实现.

编辑

这是另一种适用于非菜单视图的方法:

onView (withID(R.id.menu_delete))
  .check(matches(withEffectiveVisibility(ViewMatchers.Visibility.GONE)));
