经过Espresso测试的视图位于对话框下方，因此Espresso无法找到它 [英] Espresso tested view is below dialog and therefore Espresso can't find it

问题描述

我想验证用户界面上是否有一些任意文本的视图.因此，我正在使用:

I want to verify that there's a view on the UI that mathces some arbitary text. Therefore I'm using:

onView(withId(R.id.my_view_id)).check(matches(withText("my text")));

问题在于，根据设备的电池电量，可能会出现一个对话框，提示电池电量低.

The problem is though that depending on the battery level of the device there might be a dialog saying that the battery level is low.

将显示的对话框是普通的AlertDialog.

The dialog that will be shown is a normal AlertDialog.

如果我不显示对话框，则上面的espresso语句显示的那一刻我的测试运行正常.

My test runs fine if I don't show the dialog, the moment I'll show it the above espresso statement fails.

如何告诉espresso我不在乎对话框，而只想查找视图?当Espresso尝试在AlertDialog上找到视图R.id.my_view_id时.

How can I tell espresso that I don't care about the dialog and just want to find the view? As Espresso is trying to find the view R.id.my_view_id on the AlertDialog.

推荐答案

好吧，我也看到了chiuki以外的另一种解决方案.

Well, I see also another solution than chiuki.

有@Before个注释，您可以将其添加到类似方法中

There's @Before annotation which you may add to method like

@Before
public void checkIfAlertDialogIsShown() {
   //your code
}

此方法将在每次Espresso测试之前运行.因此，您可以检查这种电量不足的情况是否发生.

This method would run before every Espresso test. So you can check if this battery-low situation happens.

很遗憾，Espresso无法捕获AlertDialog或系统通知.为此，您可以使用另一个名为uiautomater的出色Google工具.它与Espresso搭配使用效果很好，因此您可以同时使用它们.

Unfortunately, Espresso can't catch AlertDialog or system notifications. For this purpose you can use another great Google's tool called uiautomater. It works good with Espresso, so you may use both of them.

因此在@Before带注释的方法中，您将使用uiatomater框架检查是否发生了这种情况.如果为true，则您将关闭此对话框.

So in @Before annotated method you would check using uiatomater framework if it happens. If true, than you would close this Dialog.
