Question

@Test
public void shouldLogUserIn(){
    //type in uername/password and close softkeyboard
    onView(withId(R.id.username)).perform(typeText("username"));
    onView(withId(R.id.userpassword)).perform(typeText("password"), closeSoftKeyboard());

    //click login_button
    onView(withId(R.id.login_button)).perform(click());

    //wait for login background task, should take 5seconds at most
    Systemclock.sleep(3000);

    --- it fails here even increasing wait time to 2 minutes on slow emulator ---

    //rest of the test codes here...
}

以下是引发的错误：

我正在使用Espresso框架测试一个简单的Android应用程序。上面的测试在真实的设备上，在快速仿真器上甚至在Circleci上都通过了，但在慢速仿真器上总是失败，我故意这样做。

应该将这种类型的测试视为合格或标记为通过吗？

Answer 1

您的测试应同时针对快速/慢速设备的互联网连接，不同的屏幕尺寸等通过。您的方法的问题在于，即使不需要这样做，每个设备也将等待3秒。您可以选择等待的最大秒数阈值，但是您应该检查是否在较小的时间间隔内查看视图，以防止进一步等待。想象一下，您将进行80个测试，并且每个测试都需要等待3秒钟才能登录，这将导致4分钟的测试完成时间。在真实的应用中，这种情况会变得更糟。

<div class='header'>
  <div class='logo'><img src='...' /></div>
  <ul type="none" class='menu'>
    <li class='dropdown'><span>Features ▾</span></li>
    <ul class='features-menu'>
      <li><a href='#'>Harder</a></li>
      <li><a href='#'>Better</a></li>
      <li><a href='#'>Faster</a></li>
      <li><a href='#'>Stronger</a></li>
    </ul>
    <li><a href='#'>Blog</a></li>
    <li><a href='#'>Subscribe</a></li>
    <li><a href='#'>About</a></li>
  </ul>
</div>

您可以发挥创造力，并使该结构与任何其他断言/匹配器一起使用，我将留给您。完美的等待时间没有确定的配方，您应该自己决定

在考虑通过测试之前，测试应该通过慢速模拟器吗？
