戈朗 : Testing with init() func

大家好,我是Go的新手,我正在编写一个简单的应用程序,它从env变量中获取一些配置。我在init函数中执行此操作,如下所示。typeenvVarsstruct{Hoststring`env:"APP_HOST"`Usernamestring`env:"APP_USERNAME"`Passwordstring`env:"APP_PASSWORD"`}varenvConfigenvVarsfuncinit(){iferr:=env.Parse(&envConfig);err!=nil{log.Fatal(err)}}我写了测试来验证环境变量是否被正确读取。但问题是我的程序的initfunc
