android - 旋转按钮 Espresso 测试点击不工作

问题描述

我正在玩意式浓缩咖啡，我注意到我的一个按钮无法点击。我试图在屏幕上移动它并让它自动点击，但失败了。然后我注意到它有一个rotation=180. 并且通过删除它问题似乎得到了解决，但它是必要的。

这是我的测试代码：

@Test
public void orderUp() throws Exception {
    onView(ViewMatchers.withId(R.id.move_up)).perform(ViewActions.click());
    onView(withText("Up")).inRoot(withDecorView(not(is(menuActivityTestRule.getActivity().getWindow().getDecorView())))).check(matches(isDisplayed()));
}

那么，如何使测试用例适用于旋转按钮？

编辑：“错误日志表明未找到我认为的 Toast”

解决方案

ViewActions.click在屏幕上查找视图的坐标，然后在坐标上执行/模拟点击。我不太确定，但似乎setRotation可能影响了坐标计算。另一种解决方案是创建自定义点击操作：

public static ViewAction forceClick() {
    return new ViewAction() {
        @Override public Matcher<View> getConstraints() {
            return allOf(isClickable(), isEnabled());
        }

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

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

performClick()此操作通过调用而不找到其坐标来执行单击视图。但请确保视图在应用程序中附加了点击侦听器

onView(withId(R.id.move_up)).perform(forceClick());
