我目前正在努力在实现LoaderManager.LoaderCallbacks的Android ListActivity上实现功能测试.此Activity有一个简单的布局,其中包含一个EditText,供用户输入一些字符串; ListView,它通过Custom CursorAdapter填充,从自定义内容提供程序获取数据,并使用LoadManager自动更新列表视图内容它改变.

此ListActivity的预期功能仅供用户在EditText上输入一些内容并从ListView中选择一个或多个项目.

为了实现这个功能测试,我正在使用Expresso,这里是我的实现:

public class NewWordActivityFunctionalTest extends ActivityInstrumentationTestCase2<NewWordActivity>{

    public NewWordActivityFunctionalTest() {
        super(NewWordActivity.class);
    }

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        getActivity();
    }

    public void testFillNewThemeFormAndSubmit() throws InterruptedException {
        onView(withId(R.id.submit_new_word_button))
        .perform(click());
    }
}

如果我运行它,我得到的错误堆栈跟踪如下:
