Test

你可以覆盖 100% 的代码行，但你永远无法覆盖 100% 的输入和状态组合

  • 单元测试 (Unit Testing): 验证开发者对代码单元在预期输入下的行为。
  • 模糊测试 (Fuzz Testing): 通过自动生成大量随机或变异输入，探索代码的边缘情况和未知缺陷。Go 1.18 已将 Fuzz Testing 内置到标准工具链中，这是一个强大的武器。
  • 集成测试 (Integration Testing): 验证模块间的交互。
  • 端到端测试 (End-to-End Testing): 模拟真实用户场景。
  • 生产测试/灰度发布 (Staged Rollouts / Canary Releases): 在真实生产环境中，小范围、逐步地验证变更的可靠性，这是大型系统发布的“金丝雀”。

  • mod

    go mod tidy is used to clean up the module directory by removing any unnecessary files, such as: Unused dependencies, Duplicate entries, Empty directories

    go mod vendor is a part of Go’s vendor tooling, which allows you to manage dependencies in your project by creating a separate directory called vendor. This directory contains all the dependencies required for your project.

    Purpose: go mod tidy is used for cleaning up the module directory, while go mod vendor is used for managing dependencies in a separate vendor directory.

    Output: go mod tidy updates the go.mod file, while go mod vendor creates or updates the vendor directory.
