  • 0

I know that in Android, the extra test testAndroidTestCaseSetUpProperly is often added to test cases (not sure whether it happens all the time). I’ve never needed to give it much though before, but whilst analysing some tests which use a ContentProvider I noticed something strange.

When I added the following logging in my ContentProvider:

static
{
    Log.d("UKMPG", "Initialising URIMatcher");
    uriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
    //add uris
}

    @Override
public boolean onCreate()
{
    Log.d("UKMPG", "onCreate() called in ContentProvider");
    //set up db
}

I notice that these logs appear twice in logcat (blank lines added by me):

The first time they are logged, the application column is blank, but the second time my top level package appears.

Any ideas what this extra test does?

    It asserts that the context field in a TestCase is not null.

    //In android.test.AndroidTestCase class
public void testAndroidTestCaseSetupProperly() {
    assertNotNull("Context is null. setContext should be called before tests are run", mContext);        
}
