单击不完全可见的图像按钮加浓咖啡

ui-testing android-espresso testing android

我有个习惯 ImageButton 按设计,它是不完全可见的,因此当我执行单击操作时,会出现以下错误:

android.support.test.espresso.PerformException: Error performing 'single click' on view 'with id: test.com.myproject.app:id/navigationButtonProfile'.
Caused by: java.lang.RuntimeException: Action will not be performed because the target view does not match one or more of the following constraints:
at least 90 percent of the view's area is displayed to the user.

按钮的一小部分在屏幕外(即,它在顶部裁剪),可能有12%的按钮在屏幕外。这是设计的,不可能滚动或执行任何视图操作以使其可见。有人知道如何克服这个90%的限制吗?

解决方案: 我按照建议创建了自己的点击操作,而且效果很好。我从 Google Espresso 并且在该方法中从90变为75:

    @Override
    @SuppressWarnings("unchecked")
    public Matcher<View> getConstraints() {
        Matcher<View> standardConstraint = isDisplayingAtLeast(75);
        if (rollbackAction.isPresent()) {
            return allOf(standardConstraint, rollbackAction.get().getConstraints());
        } else {
            return standardConstraint;
        }
    }

以上这些都不适用于我。这里有一个自定义匹配器,它可以完全删除该约束,并允许您单击视图

 onView(withId(yourID)).check(matches(allOf( isEnabled(), isClickable()))).perform(
            new ViewAction() {
                @Override
                public Matcher<View> getConstraints() {
                    return ViewMatchers.isEnabled(); // no constraints, they are checked above
                }

                @Override
                public String getDescription() {
                    return "click plus button";
                }

                @Override
                public void perform(UiController uiController, View view) {
                    view.performClick();
                }
            }
    );

我不认为有任何简单、优雅的解决方案。90%的约束是硬编码的 GeneralClickAction ,并且该类是最终的,因此我们不能重写 getConstraints .

我会根据 GeneralClickAction 's code ,跳过 isDisplayingAtLeast 检查

您必须滚动到以下按钮:

onView(withId(R.id.button_id)).perform(scrollTo(), click());

这有助于我在运行测试时解决按钮可见性问题

public static ViewAction handleConstraints(final ViewAction action, final Matcher<View> constraints)
{
    return new ViewAction()
    {
        @Override
        public Matcher<View> getConstraints()
        {
            return constraints;
        }

        @Override
        public String getDescription()
        {
            return action.getDescription();
        }

        @Override
        public void perform(UiController uiController, View view)
        {
            action.perform(uiController, view);
        }
    };
}

public void clickbutton()
{
    onView(withId(r.id.button)).perform(handleConstraints(click(), isDisplayingAtLeast(65)));
}

默认点击Espresso需要视图可见性 > 90% .你觉得创建自己的 click ViewAction? 这样地。。。

public final class MyViewActions {
   public static ViewAction click() {
      return new GeneralClickAction(SafeTap.SINGLE, GeneralLocation.CENTER, Press.FINGER);
    }
}

单击将单击视图的中心。

然后可以执行如下单击: onView(withId(....)).perform(MyViewActions.click());

我希望它能奏效。

创建自己的ViewAction类,不受视图可见性约束:

 public static ViewAction myClick() {

    return new ViewAction() {
        @Override
        public Matcher<View> getConstraints() {
            return ViewMatchers.isEnabled(); // no constraints, they are checked above
        }

        @Override
        public String getDescription() {
            return null;
        }

        @Override
        public void perform(UiController uiController, View view) {
            view.performClick();
        }
    };

}

然后使用它:

onView(withId(R.id.your_view_id)).perform(myClick());

Kotlin版本:

fun myClick(): ViewAction = object : ViewAction {
  override fun getConstraints(): Matcher<View> = ViewMatchers.isEnabled() // no constraints, they are checked above

  override fun getDescription(): String = ""

  override fun perform(uiController: UiController, view: View) {
    view.performClick()
  }
}

对于我最后在文本视图上犯的同样错误,上面发布的答案和其他SO问题非常有用。我试过了 scrollTo 方法,但由于某种原因,错误仍然存在。希望这对某人有所帮助。

        onView(allOf(withId(R.id.recycler_view), isDisplayed())).perform(RecyclerViewActions
                .actionOnItem(hasDescendant(withText("my text")), click()));
