NPE in setUp() method for a ProviderTestCase subclass

Question

I currently have the following setUp() method in my ProviderTestCase2. It throws an NPE deep inside the Android API after the call to newResolverWithContentProviderFromSql(). What am I doing wrong and how do I fix it?

public void setUp() throws IllegalAccessException, InstantiationException {
    this.resolver = newResolverWithContentProviderFromSql(this.getMockContext(),
            "test.", BaseballCardProvider.class,
            BaseballCardContract.AUTHORITY,
            BaseballCardSQLHelper.DATABASE_NAME,
            BaseballCardSQLHelper.SCHEMA_VERSION, CREATE_TABLE
                    + INSERT_DATA);
}

Here's the stack trace for reference:

Answer 1

Since you have overriden setUp() but not called up to super.setUp(), the TestCase isn't complete because like the documentation says:

This framework is set up automatically by the base class' setUp() method. If you override this method, you must call the super method as the first statement in your override.
