程序配置管理
测试验证包
要考虑测序的是否如预期运行
如果定义单元测试
- 包的命名规范: pkg_test 我想测试 LoadConfigFromYaml 这个函数能不能正常运行, Go里的每一个Package 都允许有2个包:
- pkg: 目标包
- pkg_test: 正对目标包的测试包
- 定义测试函数: TestLoadConfigFromYaml(t *testing.T)
- TestXXXX
- (t *testing.T)
如何查看单测单元的信息
在单元测试里: 是不是被显示
t.Log(config.Get())
我Run时, vscode生成的 go test命令
Running tool: /usr/local/go/bin/go test -timeout 300s -run ^TestLoadConfigFromYaml$ gitlab.com/go-course-project/go17/book/config -v -count=1
怎么才能配置vscode 添加go test的 参数, 你需要对的vscode做配置
修改 TestFlag
"go.testFlags": [
"-v",
"-count=1"
],
- -v 就是打印 debug信息, t.Log的信息
- -count=1: 必须执行一次
为你的对象实现Stringger 接口
// &{0x102317ec0 0x10231c8a0}
//
// String() string, fmt.Strigger接口
//
// fmt.
func (c *Config) String() string {
v, _ := json.Marshal(c)
return string(v)
}
