如何断言未显示对话框?

目前我有一个测试,它检查对话框中是否不存在文本

onView(withText("Mobile connection")).inRoot(isDialog()).check(doesNotExist());

但我得到一个 NoMatchingRootException
android.support.test.espresso.NoMatchingRootException: Matcher 'is dialog' did not match any of the following roots: [Root{application-window-token=android.view.ViewRootImpl$W@9acefba, window-token=android.view.ViewRootImpl$W@9acefba, has-window-focus=true, layout-params-type=1, layout-params-string=WM.LayoutParams{(0,0)(fillxfill) ty=1 fl=#81810100 wanim=0x1030465 needsMenuKey=2}, decor-view-string=DecorView{id=-1, visibility=VISIBLE, width=768, height=1280, has-focus=true, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=5}}]

最佳答案

在显示之前,您无法检查是否显示对话框的文本。
onView(withText("Mobile connection")).inRoot(isDialog())
.check(doesNotExist());

您可能知道,此代码检查 Dialog 是否有显示文本的 View ,但由于没有对话框,您无法完成这部分测试。它是说:“没有根,没有对话框,我怎么能做到这一点?”

在加载之前不要检查 View 的属性。
