android 测试 onActivityResult

Question

我正在寻找一种解决方案来让我的测试(实际上是一个 ActivityInstrumentationTextCase2)使用特殊(模拟)请求/结果代码和 Intent 测试我的 Activity 的 onActivityResults 方法...

代码:应测试方法:

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
        //In this case the user selected an image from his harddrive
        case StartupActivity.PICK_IMAGE:
            if (resultCode == Activity.RESULT_OK) {
                this.processSelectedFile(data.getData());
            }
            break;
        }
    }

测试类:

public void testOnActivityResult() {
        //here I would like to call the onActivityResult method from my mActivity object.
    }

Answer 1

要测试 protected 成员，请(在您的测试项目中)声明一个从您的目标派生的新类:

public class TestMyActivity : MyActivity
{

  //constructors

   public void testOnActivityResult(int requestCode, int resultCode, Intent data) { 
       //call super one
       super.onActivityResult(requestCode, resultCode, data);
   }

}

现在在您的测试中，创建其中一个，您可以调用该方法。
