Espresso测试------SeekBar测试

一门选修的大作业需要对一个app进行测试，在使用Espresso进行集成测试的时候遇到了SeekBar组件，查了好长时间才找到，特此记录下来。

设置seekbar的值

public static ViewAction setProgress(final int progress) {
    return new ViewAction() {
        @Override
        public void perform(UiController uiController, View view) {
            SeekBar seekBar = (SeekBar) view;
            seekBar.setProgress(progress);
        }
        @Override
        public String getDescription() {
            return "Set a progress on a SeekBar";
        }
        @Override
        public Matcher<View> getConstraints() {
            return ViewMatchers.isAssignableFrom(SeekBar.class);
        }
    };
}

然后使用下面这句话进行调用

onView(withId(R.id.sb_new_task_progress))
        .perform(setProgress(90));

获取seekbar的值

public int getProgress(Matcher<View> matcher) {
    final int[] progress = {0};
    onView(matcher).perform(new ViewAction() {
        @Override
        public Matcher<View> getConstraints() {
            return ViewMatchers.isAssignableFrom(SeekBar.class);
        }

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

        @Override
        public void perform(UiController uiController, View view) {
            SeekBar seekBar = (SeekBar)view;
            progress[0] = seekBar.getProgress();
        }
    });
    return progress[0];
}

使用下面这句话进行调用

int progress = getProgress(withId(R.id.sb_new_task_progress));
onView(withId(R.id.new_task_progress)).check(matches(withText(progress+"%")));
