使用带有自定义 EditText 的 espresso [英] Use espresso with custom EditText

问题描述

这是我的布局的一部分:

Here is part of my layout:

<com.rey.material.widget.EditText
            android:id="@+id/tagEditorSettings"
            android:layout_width="match_parent"
            android:layout_height="48dp"
            android:layout_marginStart="10dp"
            android:layout_toEndOf="@+id/circularProgressbar"
            android:hint="@string/tag_name_tag_settings"
            android:inputType="text"
            android:textSize="18sp"
            app:et_dividerColor="@color/my_primary"
            app:et_dividerHeight="1dp"
            app:et_inputId="@+id/name_input"
            app:et_labelEnable="true"
            app:et_labelTextSize="14sp"
            app:et_supportLines="1" />

和我的测试代码:

onView(withId(R.id.tagEditorSettings))
                .perform(click()).perform(clearText());

当我尝试运行它时，我得到这样的错误:

And when I try to run it I get such error:

Caused by: java.lang.RuntimeException: Action will not perform因为目标视图与以下一项或多项不匹配约束条件:(在屏幕上显示给用户并且是可分配的来自类:类 android.widget.EditText)

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 is assignable from class: class android.widget.EditText)

据我所知，问题在于可从类中分配:class android.widget.EditText"，但有人可以请教，我如何修复它并在我的情况下使用?

As I understand the problem is with "is assignable from class: class android.widget.EditText", but could someone please advice, how I can fix it and use in my case?

推荐答案

问题:com.rey.material.widget.EditText 扩展自 Framelayout 和 clearText 使用 ReplaceTextAction 为

Issue: com.rey.material.widget.EditText is extended from Framelayout and clearText uses ReplaceTextAction as

  public static ViewAction clearText() {
      return actionWithAssertions(new ReplaceTextAction(""));
  }

其中 ReplaceTextAction 强制执行 view，一种 EditText as

where ReplaceTextAction enforces the view, a type of EditText as

allOf(isDisplayed(), isAssignableFrom(EditText.class));
//                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

由于 rey...EdiText 不是 EditText 的子类，因此错误

Since rey...EdiText is not a subclass of EditText hence the error

解决方案:创建您自己的ViewAction作为

public static ViewAction clearTextInCustomView(){
            return new ViewAction() {
                @SuppressWarnings("unchecked")
                @Override
                public Matcher<View> getConstraints() {
                    return allOf(isDisplayed(), isAssignableFrom(com.rey.material.widget.EditText.class));
//                                            ^^^^^^^^^^^^^^^^^^^ 
// To check that the found view is type of com.rey.material.widget.EditText or it's subclass
                }

                @Override
                public void perform(UiController uiController, View view) {
                    ((com.rey.material.widget.EditText) view).setText("");
                }

                @Override
                public String getDescription() {
                    return "clear text";
                }
            };
    }

然后你可以做

onView(withId(R.id.tagEditorSettings))
                .perform(click()).perform(clearTextInCustomView());
