android - Espresso - 单击对话框的按钮

Question

我想测试一下Android 6的权限，但是没有找到使用Espresso点击“允许”按钮的方法。有办法做到这一点吗？

Espresso 的版本是 2.2.1。

测试:

    @Test
    public void acceptFirstPermission() throws Exception {
        onView(withText("ALLOW")).perform(click());
    }

行为:

I still receiving the frozen screen with the Dialog (like on the screenshot). Test executing all time until he becomes finished.

输出:

Running tests
Test running started
android.support.test.espresso.NoActivityResumedException: No activities in stage RESUMED. Did you forget to launch the activity. (test.getActivity() or similar)?

我看到您正在尝试测试应用权限。我认为用 Espresso 测试它可能几乎是不可能的。您可能需要使用另一个名为 uiatomator 的 UI 测试工具来执行此操作。

uiatomator，Google 制作的另一款很棒的工具，可让您测试 Android 系统功能，例如通知和屏幕锁定。您可以将它与 Espresso 测试框架一起使用。
