如果在的AsyncTask 通过一个按钮点击事件触发，我怎么能测试它 - 我怎么能等到AsyncTask的完成？

请注意我总是直接在我的测试方法执行的AsyncTask ，我知道如何测试这样的场景。不过，如果我坚持使用模拟使用的onClick 事件 performClick（）我还可以测试我的注册过程？

MainActivityFunctionalTest

 公共类MainActivityFunctionalTest扩展            ActivityInstrumentationTestCase2＆LT; MainActivity＆GT; {    // ...        公共无效testRegistration（）{        的ImageButton submitBtn =（的ImageButton）solo.getView（R.id.BtnR）;        assertNotNull（submitBtn）;        submitBtn.performClick（）;                //当注册完成后如何做？        }    // ...    } 

MainActivity （将要测试的项目）

 的ImageButton submitBtn =（的ImageButton）findViewById（R.id.BtnRegister）;submitBtn.setOnClickListener（新OnClickListener（）{            公共无效的onClick（视图v）{                sendRegistration（）;            }        }）;公共无效sendRegistration（）{        处理器处理器=新处理器（）; // AsyncTask的子类        processor.execute（）;    } 

解决方案

你可以这样做：

  myAsyn的obj =新myAsyn（）;obj.execute（）;而（obj.getStatus（）== AsynTask.status.Finished）{//在这儿等着}//当它完成，这code将要执行。 

If the AsyncTask is triggered by a click event on a button, how can I test it - how can I wait until the AsyncTask completes?

Note I can always execute the AsyncTask directly in my test method, I know how to test such scenario. However, if I insist on on using simulating the onClick event using performClick() can I still test my registration process?

MainActivityFunctionalTest

public class MainActivityFunctionalTest extends
            ActivityInstrumentationTestCase2<MainActivity> {
    // ...
        public void testRegistration() {
        ImageButton submitBtn = (ImageButton) solo.getView(R.id.BtnR);
        assertNotNull(submitBtn);


        submitBtn.performClick();
                // How to do something when the registration is done?
        }
    // ...
    } 

MainActivity (of the project to be tested)

ImageButton submitBtn = (ImageButton) findViewById(R.id.BtnRegister);
submitBtn.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                sendRegistration();
            }
        });

public void sendRegistration() {
        Processor processor = new Processor();// subclass of AsyncTask
        processor.execute();
    }

you can do :

myAsyn obj = new myAsyn();
obj.execute();

while(obj.getStatus()==AsynTask.status.Finished)
{
//wait here
}

//when it finishes , this code will going to execute.
