Executing Go Tests Underscore (_) in place of correct path
问题
感谢您的帮助。
在我的Mac上，当我执行go test ./...命令时，正确的“路径”会在输出中显示：
ok github.com/cnuss/server 0.008s
ok github.com/cnuss/server/database 0.008s
? github.com/cnuss/server/handlers [没有测试文件]
ok github.com/cnuss/server/stats 0.014s
然而，在Ubuntu 14.04 Trusty容器中构建时，路径被替换为“_”（下划线）：
ok _/tmp/cnuss/server 0.003s
ok _/tmp/cnuss/server/database 0.003s
? _/tmp/cnuss/server/handlers [没有测试文件]
ok _/tmp/cnuss/server/stats 0.008s
路径的更改也反映在-coverprofile输出文件中，这影响了我正在使用的一些覆盖工具。
所以问题是，是什么影响了执行go test时解析的路径？在我的Mac Book上的行为是正确的。
英文:
thanks in advance for the help.
On my Mac, when I execute a go test ./... the correct "path" is outputted in the output:
ok github.com/cnuss/server 0.008s
ok github.com/cnuss/server/database 0.008s
? github.com/cnuss/server/handlers [no test files]
ok github.com/cnuss/server/stats 0.014s
However, when I build in an Ubuntu 14.04 Trusty container, the path has been replaced by an "_" (underscore):
ok _/tmp/cnuss/server 0.003s
ok _/tmp/cnuss/server/database 0.003s
? _/tmp/cnuss/server/handlers [no test files]
ok _/tmp/cnuss/server/stats 0.008s
The change in the path is also reflected in the -coverprofile output file, which in turns affects some of the coverage tools I'm using.
So question is, what affects the path that is resolved while executing go test? The behavior on my Mac Book is the correct behavior.

你的Linux环境可能没有设置GOPATH。
如果我在当前目录下创建一个名为src/foo/foo.go的文件，内容为package foo，我可以看到差异：
$ unset GOPATH
$ go test ./src/foo
? _/home/james/.../src/foo [没有测试文件]
$ export GOPATH=`pwd`
$ go test ./src/foo
? foo [没有测试文件]
如果没有设置GOPATH（或者包在GOPATH之外），它会像这是一个相对导入一样处理。
英文:
You probably don't have GOPATH set in your Linux environment.
If I create a file src/foo/foo.go in the current directory with the contents package foo, I can see the difference:
$ unset GOPATH
$ go test ./src/foo
? _/home/james/.../src/foo [no test files]
$ export GOPATH=`pwd`
$ go test ./src/foo
? foo [no test files]
Without GOPATH set (or with a package outside of GOPATH), it is acting as if this is a relative import.
