Let me see if I understand exactly what you want (ironically, I
learned RhinoMocks with the AAA syntax and I find it hard sometimes to
follow the record/play syntax). The SearchManager class you're
testing has the following members:
ISearchDAO SearchDAO { get; set; }
IServiceAreaDAO ServiceAreaDAO { get; set; }
ArticleSearchResult SearchForArticles(ArticleSearchCriteria criteria,
int[] serviceAreaIds)
You want to ensure that the when calling SearchForArticles, the
results of any calls made to ServiceAreaDAO.GetById(int) are added to
the criteria.ServiceAreas collection?
