Mocks Aren't Stubs, Fakes, Dummies or Spies - SymfonyLive LondonĀ 2014

If you're familiar with testing your PHP code, there's a good chance you've been using mock objects: But are they really mocks? The term mock object is commonly used in the PHP community to describe both Mocks and Stubs, but they do behave differently, and more importantly, they should be used differently.

Test double is used as the general name for objects, procedures or systems used to replace real components, purely for testing purposes. As the title of the talk implies, mock objects aren't the only kind of test doubles out there.

This talk will cover the basic differences between the test doubles you might use and when or what you might utilise them for, including practical examples using several of the most popular PHP test double libraries. We'll then go into a little bit more detail on how the way you approach the design of your software can lead to the use of the different types and the trade-offs between those approaches.
