How to get a complete coverage in all package golang
问题
我刚刚开始使用Go，对此还非常陌生。
我正在尝试进行完整的测试转换，但是当我运行以下命令时：
go test -cover new-project/anto/... .
在 new-project/anto/mon 目录中，它显示我的覆盖率为51.8%，但实际上我的覆盖率更高，因为在 new-project/anto/integration 目录中有一些测试是在导入 new-project/anto/mon 进行测试的。
问题在于，根据我阅读的Golang文档，只有当测试文件与被测试的代码文件在同一个文件夹中时，Go才会正确地检测到它们。
我想知道是否有一种方法可以获取完整的覆盖率信息。
go test -cover new-project/anto/... .
? new-project/anto/ [没有测试文件]
ok new-project/anto/conf 6.060秒 覆盖率：73.1%
ok new-project/anto/integration 43.309秒 覆盖率：[没有语句]
? new-project/anto/integration/conf [没有测试文件]
? new-project/anto/integration/mocks [没有测试文件]
? new-project/anto/integration/utils [没有测试文件]
ok new-project/anto/logs 0.024秒 覆盖率：70.5%
ok new-project/anto/metric 0.012秒 覆盖率：59.0%
ok new-project/anto/mon 1.612秒 覆盖率：51.8%
? new-project/anto/anotherComponents [没有测试文件]
经过一些研究，我找到了一个名为 go-acc 的插件，它可以验证所有的包。有趣的是，使用该插件后，mon 的覆盖率从51.8%降低到了29.8%。
go-acc new-project/anto/... .
? new-project/anto/ [没有测试文件]
ok new-project/anto//conf 5.030秒 覆盖率：73.1
ok new-project/anto//integration 43.117秒 覆盖率：73.5
? new-project/anto//integration/conf [没有测试文件]
? new-project/anto//integration/mocks [没有测试文件]
? new-project/anto//integration/utils [没有测试文件]
ok new-project/anto//logs 0.008秒 覆盖率：22.3
ok new-project/anto//metric 0.020秒 覆盖率：59.0
ok new-project/anto//mon 1.460秒 覆盖率：29.8
? new-project/anto//anotherComponents [没有测试文件]
? new-project/anto/ [没有测试文件]

I have just 24h working with Go so I am super new to this.
I'm trying to get a complete test conversion but when I run
go test -cover new-project/anto/... .
in new-project/anto/mon it shows me that I have 51.8% coverage but in reality I have more coverage because there are tests that are tested in new-project/anto/integration where I have a test file that I import the new-project/anto/mon for testing.
The thing is that as I was reading Golang only takes the tests if they are in the same folder but having separate files does not detect it correctly.
I was wondering if there is a way to get the full coverage.
go test -cover new-project/anto/... .
? new-project/anto/ [no test files]
ok new-project/anto/conf 6.060s coverage: 73.1% of statements
ok new-project/anto/integration 43.309s coverage: [no statements]
? new-project/anto/integration/conf [no test files]
? new-project/anto/integration/mocks [no test files]
? new-project/anto/integration/utils [no test files]
ok new-project/anto/logs 0.024s coverage: 70.5% of statements
ok new-project/anto/metric 0.012s coverage: 59.0% of statements
ok new-project/anto/mon 1.612s coverage: 51.8% of statements
? new-project/anto/anotherComponents [no test files]
Doing some research, I found a go-acc plugin that validates all the packages, the curious thing is that mon instead of having 51.8% now has 29.8%.
go-acc new-project/anto/... .
? new-project/anto/ [no test files]
ok new-project/anto//conf 5.030s coverage: 73.1
ok new-project/anto//integration 43.117s coverage: 73.5
? new-project/anto//integration/conf [no test files]
? new-project/anto//integration/mocks [no test files]
? new-project/anto//integration/utils [no test files]
ok new-project/anto//logs 0.008s coverage: 22.3
ok new-project/anto//metric 0.020s coverage: 59.0
ok new-project/anto//mon 1.460s coverage: 29.8
? new-project/anto//anotherComponents [no test files]
? new-project/anto/ [no test files]

第一条命令将为所有包生成coverage.out文件。第二条命令解析coverage.out并输出结果：
go test ./... -coverpkg=./... -coverprofile ./coverage.out
go tool cover -func ./coverage.out
示例输出：
golang.org/x/example/stringutil/reverse.go:21: Reverse 100.0%
total: (statements) 100.0%
要获取更多详细信息，请参阅以下各种帮助输出：
go help testgo help testflagsgo help packagesgo tool cover --help
英文:
The first command will generate coverage.out for all packages. The second parses the coverage.out and outputs the results:
go test ./... -coverpkg=./... -coverprofile ./coverage.out
go tool cover -func ./coverage.out
Sample output:
golang.org/x/example/stringutil/reverse.go:21: Reverse 100.0%
total: (statements) 100.0%

go help testgo help testflagsgo help packagesgo tool cover --help
