你知道如何实现单元测试使用Robolectric AsyncTasks？任何指针将AP preciated。

Do you know how to implement unit testing for AsyncTasks using Robolectric ? Any pointers will be appreciated.

推荐答案

呼叫执行（...）的任务，然后等待结果电话Robolectric.runBackgroundTasks()/Robolectric.flushBackgroundThreadScheduler()那么你就可以断言。

Call execute(...) on the task, then to wait for the result call Robolectric.runBackgroundTasks()/Robolectric.flushBackgroundThreadScheduler() then you can assert.

@Test
public void test() {
    //create task
    MyAsyncTask asyncTask = new MyAsyncTask();

    //start task
    asyncTask.execute(...);

    //wait for task code
    // Robolectric.runBackgroundTasks(); (pre 3.0)
    Robolectric.flushBackgroundThreadScheduler(); //from 3.0

    //can run asserts on result now
    assert...(asyncTask.get());
}
