Ignore code blocks in Golang test coverage calculation
问题
在编写我的 Golang 代码的单元测试时，有几个方法我希望在计算覆盖率时被忽略。这是否可能？如果是，应该如何实现？

I am writing unit tests for my golang code, and there are a couple methods that I would like to be ignored when coverage is calculated. Is this possible? If so, how?

一种方法是将不想进行测试的函数放在一个单独的go文件中，并使用构建标签来防止在测试期间包含它。例如，我有时会在应用程序中这样做，其中有一个main.go文件，包含主函数、可能是一个使用函数等，这些函数不会被测试。然后，你可以添加一个测试标签或类似的东西，比如go test -v -cover -tags test，主函数可能如下所示：
//+build !test
package main
func main() {
// 做一些事情
}
func usage() {
// 显示一些使用信息
}
英文:
One way to do it would be to put the functions you don't want tested in a separate go file, and use a build tag to keep it from being included during tests. For example, I do this sometimes with applications where I have a main.go file with the main function, maybe a usage function, etc., that don't get tested. Then you can add a test tag or something, like go test -v -cover -tags test and the main might look something like:
//+build !test
package main
func main() {
// do stuff
}
func usage() {
// show some usage info
}
