golang test

前置准备：安装 mock

go install go.uber.org/mock/mockgen@latest

创建项目

go mod init github.com/killlowkey/golang-testing
go get go.uber.org/mock/gomock
go get github.com/stretchr/testify
go get github.com/gin-gonic/gin
go get gorm.io/gorm
go get gorm.io/driver/mysql
go get github.com/DATA-DOG/go-sqlmock

1. sqlmock：模拟数据库
2. mock：mock 接口
3. testify：断言框架
4. mockery

创建 mock

mockgen -source ./store/user.go -destination ./store/user_mock.go -package store UserStore
mockgen -source ./biz/user.go -destination ./biz/user_mock.go -package biz UserService

运行测试

1. 运行所有测试：go test ./...
2. 运行单个测试：go test ./biz -run TestUserService_GetUserById
3. 运行指定包下测试：go test -v ./biz
4. 运行指定测试文件(需要指定依赖)：go test -v ./biz/user_test.go ./biz/user_mock.go ./biz/user.go

   user_test.go 依赖了 user_mock.go 和 user.go，如果不指定依赖，会报错：undefined: UserServiceMock
