Android: 如何使用 Espresso 在 EditTextPreference 上执行点击操作
Android: How to perform click action on EditTextPreference using Espresso
我是 UI 测试的新手，尤其是使用 Espresso。在我的用例中，我需要检查应用程序是否接受 PreferenceScreen 片段内的 EditTextPreference 上的输入文本，但在此之前我需要执行单击以显示编辑对话框然后输入文字。
这是首选项片段具有编辑小部件的方式：
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<EditTextPreference
android:key="@string/pref_stream_target_key"
android:title="@string/pref_stream_target_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_resolution_key"
android:title="@string/pref_stream_resolution_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_bitrate_key"
android:title="@string/pref_stream_bitrate_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_framerate_key"
android:title="@string/pref_stream_framerate_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_peerlatency_key"
android:title="@string/pref_stream_peerlatency_label"
app:useSimpleSummaryProvider="true" />
</PreferenceScreen>
这就是我尝试执行点击的方式
with(launchFragmentInContainer<StreamSettingsFragment>()) {
onFragment { fragment ->
Espresso.onData(PreferenceMatchers.withTitle(R.string.pref_stream_target_label))
.perform(ViewActions.click())
}
}
我不确定是否有必要执行点击操作以检查 EditTextPreference 中更改侦听器背后的逻辑。
运行 对此进行的测试只会保留应用程序 运行 而什么都不做。有什么我想念的吗？
编辑： 让浓缩咖啡工作而不做任何事情的解决方案是将代码从 onFragment 块中取出，但是我仍然无法执行EditTextPreference 小部件的操作。
这是抛出的错误：

删除 onFragment 位 - 这样您就可以在主线程上以同步方式直接与 Fragment 交互。 Espresso 旨在在测试线程上工作，并自行处理与 UI 的同步：
launchFragmentInContainer<StreamSettingsFragment>()
onData(withTitle(R.string.pref_stream_target_label)).perform(ViewActions.click())
编辑
好的，现在你得到 No views in hierarchy found matching: is assignable from class <class android.widget.AdapterView> 。这是什么意思？这意味着 onData 试图在 AdapterView（如 ListView）中找到一个对象，但没有找到。
好的，为什么不呢？查看错误报告，您将看到：

这是什么意思？这意味着 PreferenceFragment 为其项目使用 RecyclerView 而不是 ListView。因此，PreferenceMatchers 和 onData 将不起作用。
好的，那你怎么办？对于 RecyclerViews，您可以使用 RecyclerViewActions。
您之前的尝试可能会转化为类似以下内容：
// We know the ID from the error stacktrace you were given
onView(withId(R.id.recycler_view))
.perform(actionOnItem<RecyclerView.ViewHolder>(
// Find the preference that has "target label" text view as a subview
hasDescendant(withText(R.string.pref_stream_target_label)),
click() // And click it
))
我是 UI 测试的新手，尤其是使用 Espresso。在我的用例中，我需要检查应用程序是否接受 PreferenceScreen 片段内的 EditTextPreference 上的输入文本，但在此之前我需要执行单击以显示编辑对话框然后输入文字。
这是首选项片段具有编辑小部件的方式：
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<EditTextPreference
android:key="@string/pref_stream_target_key"
android:title="@string/pref_stream_target_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_resolution_key"
android:title="@string/pref_stream_resolution_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_bitrate_key"
android:title="@string/pref_stream_bitrate_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_framerate_key"
android:title="@string/pref_stream_framerate_label"
app:useSimpleSummaryProvider="true" />
<EditTextPreference
android:key="@string/pref_stream_peerlatency_key"
android:title="@string/pref_stream_peerlatency_label"
app:useSimpleSummaryProvider="true" />
</PreferenceScreen>
这就是我尝试执行点击的方式
with(launchFragmentInContainer<StreamSettingsFragment>()) {
onFragment { fragment ->
Espresso.onData(PreferenceMatchers.withTitle(R.string.pref_stream_target_label))
.perform(ViewActions.click())
}
}
我不确定是否有必要执行点击操作以检查 EditTextPreference 中更改侦听器背后的逻辑。
运行 对此进行的测试只会保留应用程序 运行 而什么都不做。有什么我想念的吗？
编辑： 让浓缩咖啡工作而不做任何事情的解决方案是将代码从 onFragment 块中取出，但是我仍然无法执行EditTextPreference 小部件的操作。
这是抛出的错误：

删除 onFragment 位 - 这样您就可以在主线程上以同步方式直接与 Fragment 交互。 Espresso 旨在在测试线程上工作，并自行处理与 UI 的同步：
launchFragmentInContainer<StreamSettingsFragment>()
onData(withTitle(R.string.pref_stream_target_label)).perform(ViewActions.click())

好的，现在你得到 No views in hierarchy found matching: is assignable from class <class android.widget.AdapterView> 。这是什么意思？这意味着 onData 试图在 AdapterView（如 ListView）中找到一个对象，但没有找到。
好的，为什么不呢？查看错误报告，您将看到：

这是什么意思？这意味着 PreferenceFragment 为其项目使用 RecyclerView 而不是 ListView。因此，PreferenceMatchers 和 onData 将不起作用。
好的，那你怎么办？对于 RecyclerViews，您可以使用 RecyclerViewActions。
您之前的尝试可能会转化为类似以下内容：
// We know the ID from the error stacktrace you were given
onView(withId(R.id.recycler_view))
.perform(actionOnItem<RecyclerView.ViewHolder>(
// Find the preference that has "target label" text view as a subview
hasDescendant(withText(R.string.pref_stream_target_label)),
click() // And click it
))
