Question

I am currently writing unit tests for an application near completion (before management looks at it and turns it inside out). I am testing the business layer and a method is set to return a datatable of all “GroupID”s, which are simply an integer to represent the group that a user belongs to.

I’m assuming the best way to assert on this unit test would be to assert that the correct groupIDs are being returned from a controlled test database. However, I’m not sure how to assert on a datatable. Is the only (and best) possible way to accomplish this to simply loop through the datatable until it’s empty and add each value to an array of integers? How would one go about asserting on this test?

best way to accomplish using collection…

List<string> items = new List<string>(dtbl.Rows.Count);

    for (int RowCount = 0; RowCount < dtbl.Rows.Count; RowCount++)
    {
        items.Add(dtbl.Rows[RowCount]["ID"].ToString());
    }

    items.ToArray();
