Question

I have a very simple AsyncTask implementation example and am having problem in testing it using Android JUnit framework.

It works just fine when I instantiate and e

Most of those solutions require a lot of code to be written for every test or to change your class structure. Which I find very difficult to use if you have many situations under test or many AsyncTasks on your project.

There is a library which eases the process of testing AsyncTask. Example:

@Test
  public void makeGETRequest(){
        ...
        myAsyncTaskInstance.execute(...);
        AsyncTaskTest.build(myAsyncTaskInstance).
                    run(new AsyncTest() {
                        @Override
                        public void test(Object result) {
                            Assert.assertEquals(200, (Integer)result);
                        }
                    });         
  }       
}

Basically, it runs your AsyncTask and test the result it returns after the postComplete() has been called.
