android - Espresso - 无法使用 Espresso 执行按钮点击

Question

我目前不熟悉自动化测试和使用 Android Studio 使用 Espresso 执行自动化测试，我正在尝试对登录屏幕执行自动化测试，我目前在执行特定按钮的点击时遇到问题。我尝试了多种按钮方法，但对我没有用。我引用以下文档来实现，下面是我的示例代码和崩溃报告。

@RunWith(AndroidJUnit4.class)
@LargeTest
public class LoginTest {
    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule =
            new ActivityTestRule<>(LoginActivity.class);
    @Test
    public void OnLoginButtonClick() throws InterruptedException {
        onView(ViewMatchers.withId(R.id.edtUserName)).perform(ViewActions.typeText("xxxxx"));
        onView(ViewMatchers.withId(R.id.edtPassword)).perform(ViewActions.typeText("xxxxxxx"));
        onView(ViewMatchers.withId(R.id.btnLogin)).perform(ViewActions.scrollTo(),ViewActions.click());
    }
}

崩溃报告:

Answer 1

目标设备上启用了动画或过渡。

Espresso 不适用于动画，因为它们引入了视觉状态延迟。您需要禁用设备上的动画。首先，enable developer options

打开“设置”应用。

1. 滚动到底部并选择关于手机。

2. 滚动到底部并点击内部版本号 7 次。

3. 返回上一屏幕，在底部附近找到开发者选项。

4. 从“设置”应用访问“开发者选项”，然后在“绘图”部分下，将以下所有选项切换为“关闭动画”:

   1. 窗口动画比例
   2. 过渡动画比例
   3. 动画师持续时间比例
