Android：如何使用Espresso在EditTextPreference上執行點擊操作

2021-11-26 18:40:43 後端開發

我是 UI 測驗的新手，尤其是使用 Espresso。在我的用例中，我需要檢查應用程式是否接受片段EditTextPreference內的輸入文本PreferenceScreen，但在此之前我需要執行單擊以顯示編輯對話框，然后輸入文本。

這是首選項片段具有編輯小部件的方式：

<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>

這就是我嘗試執行點擊的方式

with(launchFragmentInContainer<StreamSettingsFragment>()) {
    onFragment { fragment ->
        Espresso.onData(PreferenceMatchers.withTitle(R.string.pref_stream_target_label))
            .perform(ViewActions.click())
    }
}

我不確定是否需要進行單擊操作以檢查EditTextPreference.

用這個運行測驗只會讓應用程式運行，什么都不做。有什么我想念的嗎？

編輯：讓 espresso 作業而不做任何事情的解決方案是將代碼從onFragment塊中取出，但是我仍然無法對EditTextPreference小部件執行操作。

這是被拋出的錯誤：

uj5u.com熱心網友回復：

洗掉該onFragment位 - 這樣您就可以在主執行緒上以同步方式直接與 Fragment 互動。Espresso 被設計為在測驗執行緒上作業并自行處理與 UI 的同步：

launchFragmentInContainer<StreamSettingsFragment>()

onData(withTitle(R.string.pref_stream_target_label)).perform(ViewActions.click())

編輯

好的，現在你明白了No views in hierarchy found matching: is assignable from class <class android.widget.AdapterView> 。這是什么意思？這意味著onData試圖在AdapterView（如 a ListView）中找到一個物件，但沒有找到。

好的，為什么不呢？查看錯誤報告，您將看到：

 ----->RecyclerView{id=2131296596, res-name=recycler_view, visibility=VISIBLE, width=1080, height=1966, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, layout-params=android.widget.FrameLayout$LayoutParams@687e0d0, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=5} 
|
 ------>LinearLayout{id=0, visibility=VISIBLE, width=1080, height=241, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, layout-params=androidx.recyclerview.widget.RecyclerView$LayoutParams@2746bce, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=3} 
|
 ------->LinearLayout{id=2131296469, res-name=icon_frame, visibility=INVISIBLE, width=168, height=24, has-focus=false, has-focusable=false, 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=android.widget.LinearLayout$LayoutParams@3bedaef, tag=null, root-is-layout-requested=false, has-input-connection=false, x=18.0, y=108.0, child-count=1} 
|
 -------->PreferenceImageView{id=16908294, res-name=icon, visibility=INVISIBLE, width=0, height=0, has-focus=false, has-focusable=false, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, layout-params=android.widget.LinearLayout$LayoutParams@2d239fc, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=12.0}

這是什么意思？這意味著它的專案PreferenceFragment使用了RecyclerViewnot a ListView。因此，PreferenceMatchers并onData不會起作用。

好的，那你怎么辦？對于RecyclerViews您，請改用RecyclerViewActions。

您之前的嘗試可能會轉化為以下內容：

// 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
    ))
