As I’ve wrote the integration tests for the pick module which also included the multi-threaded class, I’ve faced problem that the dispatcher in the multi-threaded class fails to mock. Since the multi-threaded class is used to refresh the data grid view within time interval, therefore fails to mock had caused all the integration tests fail to receive the data grid binding source to perform testing.
In order to solve the issue, I’ve decided to use the solution which is implement an interface for the dispatcher for mocking.
I’ve created the interface which called IDispatcher which include the BeginInvoke method. Then, instead of calling dispatcher, I’ve changed it to fire IDispatcher and its method as well. Lastly, in the integration tests, I call the mock for IDispatcher and setup its callback as (Action a) => a() to invoke the method in the multi-threaded class.
