Test Doubles - Designing for and using Stubs, Fakes, Mocks, and Spies

Описание: Test doubles (Stubs, fakes, mocks and spies) are unit testing techniques that allow us to test a class without needing (or wanting!) the real implementations of the things the class we are testing depends on. They allow our tests to focus on the class we are testing and ensure that, if a test fails, we know what code is broken. This video shows how we design our code so that we can use these techniques, describes what all of these are with real code examples and discusses the pros and cons of each technique.

In this video I'll walk you through:
Why we need these techniques
what each of them is and how they get coded
When each is useful and when each is insufficient

ABOUT MY CHANNEL
My channel is about good software engineering practices. We cover introductions to programming in C and Java. But I also have lots of software and computer engineering topics like PIC programming, advanced programming techniques, and things that distinguish good code from code that works.
