Hi, I'm Chris. I'm the creator of GoRails, Hatchbox.io and Jumpstart. I spend my time creating tutorials and tools to help Ruby on Rails developers build apps better and faster.

About This Episode

Mocks are a handy tool for writing tests in Ruby. You can use them to fake an object and verify that the correct methods were called against it. Perfect for testing a method that integrates closely with another class or module.

Notes

Mocks are an invaluable tool when writing tests. You can use them to replace objects in your test suite so that you can verify your code calls specific methods against them. Mocks also let you stub methods against them just like with regular stubs.

Combine with Dependency Injection, mocks allow you to write tests with interchangeable dependencies. You can use a mock to simulate interaction with an API by creating a fake API as a mock.
