如何测试的AsyncTask通过点击触发

本文介绍了如何测试的AsyncTask通过点击触发?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

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< MainActivity> {
    // ...
        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();
    }
解决方案

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.
