Saga and unit tests

[Carmine]

Hi,

I'm writing a saga with 7 states and I want to create unit tests in order to test all the stuff.

Do you have any example of this? I studied the source code tests and I've already written some ones but I can't find an easy way to transition the saga state directly in a state that I want to test.

Right now, I'm writing tests like:

            var startCommand = CreateScheduleTenderCommand();

            await InputQueueSendEndpoint.Send(startCommand);

            var foundSagaId = await ShouldContainSaga(startCommand.Email, _saga.State1);

       
                     await Bus.Publish(new EventA(instance.ManagementTaskId);

            await ShouldContainSaga(startCommand.TenderEmail, _saga.State2);

                      await Bus.Publish(new EventB(instance.ManagementTaskId);

            await ShouldContainSaga(startCommand.TenderEmail, _saga.State3);

                      await Bus.Publish(new EventC(instance.ManagementTaskId);

            await ShouldContainSaga(startCommand.TenderEmail, _saga.State4);

           // -> Ok, now I'm in the state that I want to test, so I write me test code below....

This approach works, but I think that there is another way to do this, right?

Thanks

You could just create the saga instance matching the correlationId and add it to the in memory repository. But generally I walk the sagas through the events leading up to the subject area for testing as well.

Hi Chris,

I'm having a strange issue. 

I've written an unit test like the one previously posted, but if I run it in debug mode, everything work well instead if I run it without debug, it fails with a timeout error because "_sagaRepository.ShouldContainSaga" method doesn't return a value in TestTimeout timespan.

Do you have any suggestion?

Thanks
