Isolating with stubs ;TLDR

⚡️ Stubs

Challenge

Incorporate stubs into your test suites in places where they could be used instead of a real object.

Hint: the only test suite that isn't isolated currently is Ship.test.js, as it uses the Itinerary object.

To complete this challenge, you will need to:

• Look for any places in the test suite where objects are passed into methods where it would be straightforward to stub those objects.
• Replace them with stubs.
• Run your tests again to ensure they still pass (might be better to run tests after every change).
