Which test trail should I do after Testing Fundamentals?

Is there a logical progression to take after ‘Testing Fundamentals’ trail? Test-Driven Rails or Test Doubles?

Hi @alanjudson, good question. Either trail would serve you well, but it depends on what you’re looking for. If you’re mostly working in Rails then I would suggest Test-Driven Rails, but if you want to dive deeper into more advanced testing workflows with mocks, stubs, and spies, then Test Doubles is a great choice. You should have all the knowledge you need to start either, so really it is a matter of choice.
