The object test bench is more geared towards user controls than dealing with data. It can be done, but will require a different class environment than will be used at run-time...which defeats the purpose. If you are wanting to create a true test scenario, then you will want to use the Unit Tests that are available in Team Foundation Systems. This is where we create all of our tests.Bottom line though, you need to setup your data sources that allow the BO to communicate:
MicroFour.StrataFrame.Data.DataSources.Add(New SqlDataSourceItem("","Your connection string"))
