LanguageProject Introduction
Summary
GoMock is Uber's open-source mocking framework for Go (Golang). It simplifies the creation and use of mock objects for testing Go code that relies on external dependencies or complex interfaces.
Problem Solved
Writing effective unit tests in Go often requires isolating the code under test from its dependencies (databases, external services, other components). Mocking dependencies allows developers to test specific units of code reliably and quickly without needing real external resources.
Core Features
Code Generation (`mockgen`)
Automatically generates mock source code for interfaces using reflection, reducing manual mocking effort.
Expectation Setting
Provides a flexible API for setting method call expectations, verifying call order, and returning values or errors.
Tech Stack
Go
使用场景
GoMock is essential for testing Go code that depends on external systems or interfaces. Common use cases include:
场景一：测试数据库交互逻辑
Details
Testing business logic that fetches or saves data via a database interface without needing a live database connection.
User Value
Allows for rapid, repeatable tests of data access layers without relying on external infrastructure, speeding up the development cycle.
场景二：模拟外部 API 调用
Details
Isolating and testing a service client's logic that calls an external API by mocking the API's response.
User Value
Ensures the client-side handling of API responses and errors is correct, regardless of the external service's availability or state.
