How to test a .Net Custom controls

Question

Hi,

Plese suggest guidelines and examples that how can I test .Net Controls libraries (being a tester)?

Issue background.

I'm new to C#, and Nunit/NUnitForms but have some past experience in Manual, and Automated testing. I have a problem of testing some .Net UI Controls (dll) which has been utilizing in different Verticals (Window Applications). These are not a type of drag n drop controls from toolbox, but if some one wants to use them, then these Dlls (libraries) needs to mention in App.Config file and then one can invoke them in the Source Code files (*.cs).

I did some search on Test Complete 7 but fund that we can perform black box testing for an Application under test using these controls but we can not expose all the controls methiods or properties in test complete.

SomeOne told me that try with NunitForms to get some luck. Still I am getting some hard time there also.

The libraries examples are QuerFormControl, Tree Navigation Controls, Datagrid controls (All custom made) etc.


Thanks,

Amir
