Rhino Mock Async Considerations

gistfile1.cs

public void AsyncExamples()
{
	// Async controller actions have to be called asyn:
	await controller.Create(model);
   
	// Async methods return a task, so use Task.FromResult:
	_apiClient.Stub(x => x.GetCustomersAsync(Arg<long>.Is.Anything))
				.Return(Task.FromResult(new List<Customer>()));
									   
	// If the method returns just Task and not Task<T> use true/null/1:
	_file.Stub(x => x.SavePostedFile(Arg<HttpPostedFileBase>.Is.Anything))
				.Return(Task.FromResult(true));
}
