java Espresso并没有等待键盘打开

Question

我有一个浓缩咖啡测试，我的屏幕下面有一个EditText和一个skipButton。 当我启动活动时，键盘弹出打开，集中在EditText上，并与Button重叠
现在我想为skip按钮编写一个测试，并断言之后会发生什么

问题在于，浓缩咖啡不会等待键盘打开
所以发生的是

• Espresso没有等待键盘并按下“跳过”
• 键盘滑开
• 对现在位于键盘下方的内容的断言失败

代码如下所示：

public void givenSkipped_whenConfirmed_thenMainActivityLaunched() {
  Espresso.closeSoftKeyboard();// <- Not working as espresso seems to think it is not open yet
  skipPostcodeEntry.perform(click()); //<- Can click this as keyboard is not open yet.

  warningText.check(matches(withText(R.string.some_text)));

  confirmationButton.perform(click());//<- Fails as this is now overlapped by KB

  Assert.DoesSomething()
}

我发现了一个问题，意式浓缩咖啡是not waiting for the keyboard to close的，但没有什么关于它不等待键盘打开

有人解决了这个问题吗

编辑：

当您查看closeSoftKeyboard方法时，可以找到一个名为CloseKeyboardAction的类。您可以看到，当键盘未被识别为打开时，它甚至会记录日志

 Log.w(TAG, "Attempting to close soft keyboard, while it is not shown.");

不幸的是，目前看来浓缩咖啡无法检查键盘是否在屏幕上！（https://groups.google.com/forum/#!topic/android-platform/FyjybyM0wGA）

作为一种解决方法，我们要做的是检查应该有焦点的输入字段，然后关闭键盘。这可以防止Espresso在键盘出现在屏幕上之前调用closeSoftKeyboard（）

@Test
public void testSomething() {
    EspressoExtensions.closeKeyboardOnFocused(fieldThatShouldHaveFocus);
    //Continue with normal test
}

然后将EspressoExtensions添加到您的项目中：

public class EspressoExtensions {
  /**
   * This can be used to close the keyboard on an input field when Android opens the keyboard and
   * selects the first input when launching a screen.
   * <p>
   * This is needed because at the moment Espresso does not wait for the keyboard to open
   */
  public static void closeKeyboardOnFocused(ViewInteraction viewInteraction) {
    viewInteraction.check(matches(hasFocus())).perform(closeSoftKeyboard());
  }
}

希望这能有所帮助，直到浓缩咖啡能够判断键盘是否在屏幕上
