浓缩咖啡 - 单击对话框的按钮

我想测试Android 6的权限,但我找不到使用Espresso点击"允许"按钮的方法.有没有办法做到这一点？

Espresso的版本是2.2.1.

考试:

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

行为:

我仍然使用Dialog接收冻结的屏幕(如屏幕截图所示).一直测试执行直到他完成.

输出:

Egor.. 7

嗯,它可以很简单

onView(withText("Allow")).perform(click());

当然,这不是一个完美的解决方案,因此有两种方法可以使其更加健壮:使用hierarchyviewer分析应用程序以找到有关如何识别按钮的提示(例如内容描述),或者深入了解Android源代码提示(例如按钮的资源ID).

嗯,这不是那么简单.我写了一篇关于使用UiAutomator来完成这项工作的文章.

我看到你正试图测试应用程序权限.我认为用Espresso测试它可能是不可能的.您可能需要将此操作作为另一个名为的UI测试工具uiatomator.

uiatomator,Google制作的另一款出色工具可让您测试Android系统功能,如通知和屏幕锁定.您可以将它与Espresso测试框架一起使用.
