使用 espresso 测试软键盘是否可见

Question

我想在活动调用 onCreate() 和 onResume() 时测试键盘可见性。

如何测试使用 espresso 时是否显示键盘？

Answer 1

我知道，这个问题已经足够老了，但它没有任何公认的答案。 在我们的 UI 测试中，我们使用这种方法，它使用一些 shell 命令：

/**
 * This method works like a charm
 *
 * SAMPLE CMD OUTPUT:
 * mShowRequested=true mShowExplicitlyRequested=true mShowForced=false mInputShown=true
 */
fun isKeyboardOpenedShellCheck(): Boolean {
    val checkKeyboardCmd = "dumpsys input_method | grep mInputShown"

    try {
        return UiDevice.getInstance(InstrumentationRegistry.getInstrumentation())
            .executeShellCommand(checkKeyboardCmd).contains("mInputShown=true")
    } catch (e: IOException) {
        throw RuntimeException("Keyboard check failed", e)
    }
}

希望，这对某人有用

Answer 2

fun isKeyboardShown(): Boolean {
    val inputMethodManager = InstrumentationRegistry.getInstrumentation().targetContext.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    return inputMethodManager.isAcceptingText
}

另一个技巧可能是检查您知道键盘显示时将被覆盖的视图的可见性。不要忘记考虑动画...

使用 espresso 和 hamcrest 进行 NOT 匹配器的仪器测试，例如：

//make sure keyboard is visible by clicking on an edit text component
    ViewInteraction v = onView(withId(R.id.editText));
    ViewInteraction v2 = onView(withId(R.id.componentVisibleBeforeKeyboardIsShown));
    v2.check(matches(isDisplayed()));
    v.perform(click());
    //add a small delay because of the showing keyboard animation
    SystemClock.sleep(500);
    v2.check(matches(not(isDisplayed())));
    hideKeyboardMethod();
    //add a small delay because of the hiding keyboard animation
    SystemClock.sleep(500);
    v2.check(matches(isDisplayed()));

Answer 4

这对我有用。

private boolean isSoftKeyboardShown() {
    final InputMethodManager imm = (InputMethodManager) getActivityInstance()
           .getSystemService(Context.INPUT_METHOD_SERVICE);

    return imm.isAcceptingText();
}

这个方法对我有用

val isKeyboardOpened: Boolean
    get() {
        for (window in InstrumentationRegistry.getInstrumentation().uiAutomation.windows) {
            if (window.type == AccessibilityWindowInfo.TYPE_INPUT_METHOD) {
                return true
            }
        }
        return false
    }

Answer 6

fun checkIsKeyboardDisplayed(expectedIsDisplayed: Boolean) {
  val actualIsDisplayed: Boolean
  val checkKeyboardCmd = "dumpsys input_method | grep mInputShown"
  try {
    actualIsDisplayed = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation())
      .executeShellCommand(checkKeyboardCmd).contains("mInputShown=true")
  } catch (e: IOException) {
    throw RuntimeException("Keyboard check failed", e)
  }
  Assert.assertTrue(actualIsDisplayed == expectedIsDisplayed)
}`enter code here`

Answer 7

您可以使用标准 insets API 来断言软键盘可见。

view.rootWindowInsets.isVisible(WindowInsets.Type.ime())

如果您使用 compose-ui-test，您可以使用其

waitUntil { }

API：

@get:Rule val rule = createAndroidComposeRule<TestActivity>()

rule.waitUntil {
  rule.activity.window.decorView.rootWindowInsets.isVisible(WindowInsets.Type.ime())
}
