This repository contains the refactored code for The Engineering Coach's video, which demonstrates the transition from custom, hand-coded Test Doubles to the use of the GoMock mocking framework.
This is a crucial step in a professional Golang TDD workflow, showing you how to maintain the benefits of test isolation while dramatically reducing boilerplate code.
This code is a practical demonstration of how to implement a mocking framework.
➡️ Watch the video: GoMock: Replacing Hand-Coded Test Doubles in Golang
- Efficiency over Manual Implementation: See the before-and-after comparison of using hand-coded Mocks versus framework-generated Mocks.
- GoMock Integration: Learn how to install and integrate the GoMock framework into your Golang project.
- Refactoring for Cleanliness: Understand how to refactor your tests to be more expressive and concise using framework assertions and expectations.
Clone the repository:
git clone https://github.com/testingallthethings/031-gomock cd 031-gomock
Generate Mocks (Crucial Step): GoMock uses a code generator to create the necessary mock files.
