Unit tests with xamGrid as test case.
posted

Hi!

I am trying to unit test some code which manipulates a xamGrid. However, never fills with rows or columns even though I set an ItemsSource on it. This is my unit test. How can I create a XamGrid with rows and columns for testing? By the way, my project is in a WPF context, not Silverlight, but this is the only place with a XamGrid forum.

[TestFixture]
public class XamGridUtilsTests
{
   private class DataItem
   {
     public int I { get; set; }
     public string Text { get; set; }

     public DataItem(int i, string text)
     {
       I = i;
       Text = text;
     }
   }

   [Test]
   [RequiresSTA]
   public void SelectAllRows_NoneSelected_SelectsAllRows()
   {
     // Arrange
     ObservableCollection<DataItem> items = new ObservableCollection<DataItem>();
     for (int i = 1; i < 4; i++)
     {
       items.Add(new DataItem(i, "Column" + i));
     }

     XamGrid grid = new XamGrid();
     grid.AutoGenerateColumns = true;
     grid.ItemsSource = items;

     CollectionAssert.IsNotEmpty(grid.Rows);       <-- THIS FAILS
     CollectionAssert.IsNotEmpty(grid.Columns);  <-- THIS FAILS

     // Act
     XamGridUtils.SelectAllRows(grid);

     // Assert
     foreach (var row in grid.Rows)
     {
       Assert.IsTrue(row.IsSelected);
     }
   }
}
