a very simple method, but don't know what's to test!

I'd like to test this method in Business Logic Layer, and the _dataAccess apparently is from data layer.

public DataSet GetLinksByAnalysisId(int analysisId)
{
        DataSet result = new DataSet();
        result = _dataAccess.SelectAnalysisLinksOverviewByAnalysisId(analysisId);
        return result;
}

All Im testing really is to test _dataAccess.SelectAnalysisLinksOverviewByAnalysisId() is get called!

here's my test code (using Rhino mock)

[TestMethod]
public void Test()
{
   var _dataAccess = MockRepository.GenerateMock<IDataAccess>();

   _dataAccess.Expect(x => x.SelectAnalysisLinksOverviewByAnalysisId(_settings.UserName, 0, out dateExecuted));

   var analysisBusinessLogic = new AnalysisLinksBusinessLogic(_dataAccess);
   analysisBusinessLogic.GetLinksByAnalysisId(_settings, 0);

   _dataAccess.VerifyAllExpectations();

}

Let me know if you writing the test for this method what would you test against?

Many Thanks!
