The Rad components are third party controls that I do not have control
of changing the way they work. I have a helper method extension that
provides steps for frequently repeated code.
public static void AddItems(this RadComboBox comboBox,
Dictionary<string, string> items)
{
RadItemCollection collection;
RadComboBoxItem item;
comboBox.SuspendLayout();
collection = comboBox.Items;
collection.Clear();
foreach (KeyValuePair<string, string> pair in items)
{
item = new RadComboBoxItem(pair.Key, pair.Value);
item.Name = pair.Key;
collection.Add(item);
}
comboBox.ResumeLayout();
}
Due the order of SuspendLayout, clearing items, adding items, and
ResumeLayout being important I want to create an ordered test.
[TestMethod]
public void AddItems_call_in_specific_order()
{
RadItemCollection collection;
RadComboBox comboBox;
MockRepository repository;
repository = new MockRepository();
collection = repository.StrictMock<RadItemCollection>();
comboBox = repository.StrictMock<RadComboBox>();
using (repository.Ordered())
{
comboBox.Expect(c => c.SuspendLayout());
comboBox.Expect(c => c.Items).Return(collection);
collection.Expect(c => c.Clear());
collection.Expect(c =>
c.Add(null)).IgnoreArguments().Return(0);
comboBox.Expect(c => c.ResumeLayout());
}
using (repository.Playback())
{
comboBox.AddItems(testItems);
}
}
I receive an error at the collection.Expect for the c.Add as follows:
System.InvalidOperationException: Type 'System.Int32' doesn't match
the return type 'System.Void' for method
'RadItemCollection.OnInsertComplete(missing parameter, missing
parameter);'.
As I am new to using the Rhino Mock framework I don’t understand this
error. My function AddItems doesn’t call OnInsertComplete. The test
function doen’t call OnInsertComplete. I thought the purpose of
using a mock framework it that the framework emits code to stand in
place of the real code. I don’t understand why I am getting this
error because OnInsertComplete is not being tested and should not even
exist.
I am assuming OnInsertComplete is a private function because I don’t
have access to the function to do an Expect. The most important
question is how do I fix my test? I tried changing StrickMock to all
the different variations including Stub. Is there a way to emulate
the OnInsertComplete command?
