Android JUnit测试应用程序类

Question

I am trying to setup JUnit test cases for an app I am developing currently. The main problem I am facing is that I am not able to get access of an object which I am storing in my Application class. I am extending the AndroidTestCase class for writing test cases.

I tried getting access to that object(say myData) by

Myapp app = (Myapp) getContext()
                .getApplicationContext();
String myData=app.getData();

But this is throwing null pointer exception at app.getData(); how can i access this object at run time?

Answer 1

Please, show more code, class where extends AndroidTestCase , class where extends TestSuite

Also, you may forget add to AndroidManifest :

...

  <instrumentation
        android:name="android.test.InstrumentationTestRunner"
        android:targetPackage="YOUR_PACKAGE"/>

    <application
        android:label="@string/app_name"
        android:name="YOUR_APPLICATION_CLASS">

        <uses-library android:name="android.test.runner"/>

...
