[英]Espresso Doesn't Match Vector Drawables With Many Characters - ImageDrawable(AppCompatResource)
[英]How to use espresso to test vector drawables
我有一個可繪制的矢量,要使用濃縮咖啡進行測試。
<TextView
android:id="@+id/text_video_call"
style="@style/UserDetails.TextView.Actions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="24dp"
android:drawableTop="@drawable/ic_video_24dp"
android:text="@string/msg_video_call"
android:visibility="gone"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toEndOf="@+id/text_message"
app:layout_constraintTop_toBottomOf="@+id/text_username"
tools:visibility="visible" />
可繪制的向量:ic_video_24dp
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="24dp"
android:height="24dp"

有什么方法可以使用濃縮咖啡進行UI測試可繪制的矢量? 任何幫助將不勝感激。
最好不要比較位圖,而應遵循以下答案的建議: https : //stackoverflow.com/a/14474954/1396068
設置圖像視圖的可繪制對象時,還要使用setTag(R.drawable.your_drawable).
將可繪制對象ID存儲在其標記中setTag(R.drawable.your_drawable).
然后使用Espresso的withTagValue(equalTo(R.drawable.your_drawable))
匹配器檢查正確的標簽。
請也檢查一下我發現的本教程。 似乎工作得很好https://medium.com/@dbottillo/android-ui-test-espresso-matcher-for-imageview-1a28c832626f#.4snjg8frw
這是復制粘貼的摘要;-)
public class DrawableMatcher extends TypeSafeMatcher<View> {
private final int expectedId;
String resourceName;
public DrawableMatcher(int expectedId) {
super(View.class);
this.expectedId = expectedId;
}
@Override
protected boolean matchesSafely(View target) {
if (!(target instanceof ImageView)){
return false;
}
ImageView imageView = (ImageView) target;
if (expectedId < 0){
return imageView.getDrawable() == null;
}
Resources resources = target.getContext().getResources();
Drawable expectedDrawable = resources.getDrawable(expectedId);
resourceName = resources.getResourceEntryName(expectedId);
if (expectedDrawable == null) {
return false;
}
Bitmap bitmap = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
Bitmap otherBitmap = ((BitmapDrawable) expectedDrawable).getBitmap();
return bitmap.sameAs(otherBitmap);
}
@Override
public void describeTo(Description description) {
description.appendText("with drawable from resource id: ");
description.appendValue(expectedId);
if (resourceName != null) {
description.appendText("[");
description.appendText(resourceName);
description.appendText("]");
}
}
}
請注意,這僅在Drawable是BitmapDrawable時有效。 如果您也有VectorDrawable或其他Drawable,則必須檢查它(imageView.getDrawable()instanceOf XXXDrawable)並從中獲取位圖。 除了您擁有某種簡單的Drawable之外,其中您只有一種顏色,因此您可以進行比較。
為了獲得VectorDrawable的位圖,即您必須將VectorDrawable繪制到畫布上並將其保存到位圖。 如果您有一個StateListDrawable,則可以獲取所選狀態的Drawable,然后重復您的if實例cascade。
