Java 和 Espresso - 无法输入，需要支持输入法或可从 class 分配：class SearchView

Question

我正在尝试使用 Espresso 来测试带有此 xml 的应用程序：

<com.google.android.material.textfield.TextInputLayout
    android:id="@+id/tvLogin"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:hint="myHint"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <com.google.android.material.textfield.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="56dp"
        android:imeOptions="flagNoExtractUi|actionNext"
        android:inputType="text" />

</com.google.android.material.textfield.TextInputLayout>

这是我试过的测试运行:

onView(withId(R.id.tvLogin)).check(ViewAssertions.matches(ViewMatchers.isDisplayed()));
onView(withId(R.id.tvLogin)).perform(typeText("test"));

我收到这个错误：

Caused by: java.lang.RuntimeException: Action will not be performed because the target view does not match one or more of the following constraints:
((is displayed on the screen to the user) and (supports input methods or is assignable from class: class android.widget.SearchView))
Target view: "TextInputLayout{id=2131362315, res-name=tvLogin, visibility=VISIBLE, width=831, height=144, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=androidx.constraintlayout.widget.ConstraintLayout$LayoutParams@8241b55, tag=null, root-is-layout-requested=false, has-input-connection=false, x=39.0, y=39.0, child-count=2}"

Answer 1

您的 tvLogin 是一个 TextInputLayout，它也是一个 LinearLayout，因此这就是您在对其执行 typeText() 时出现错误的原因。由于 typeText() 仅适用于可编辑字段，而 TextInputEditText 是 tvLogin 的后代，您可以重写测试以使用来自 Espresso 的便捷匹配器 ViewMatchers.supportInputMethods() 之一：

onView(allOf(supportsInputMethods(), isDescendantOfA(withId(R.id.tvLogin))))
    .perform(typeText("test"))

或者，您可以为 TextInputEditText:

提供一个 ID

<com.google.android.material.textfield.TextInputEditText
    android:id="@+id/tvLoginEditText"
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:imeOptions="flagNoExtractUi|actionNext"
    android:inputType="text" />

然后在可编辑字段上执行 typeText()：

onView(withId(R.id.tvLoginEditText))
    .perform(typeText("test"))

Java and Espresso - Can't type in, needs to supports input methods or is assignable from class: class SearchView
