英文:
Running go tests from root project folder
问题
我必须接手一个Go项目，但我以前从未接触过Go，并且该项目没有测试。所以我开始添加测试，但是我无法运行它们。
运行Go测试的命令是go test，但似乎无法在根目录下运行。
我的项目结构如下：
/project/main.go
/project/engine/*.go
/project/api/*.go
如果我进入engine或api目录，并运行go test，它可以正常工作，但在根目录下不行。
cd /project
go test
? /project [no test files]
有没有办法从根目录运行所有的测试？
英文:
I have to take over a go project from a colleague and I've never touched Go before and it doesn't have tests so I've started to add them but I cannot run them.
The go command for running tests is go test but it doesn't seem to run at the root level.
My project structure is:
/project/main.go
/project/engine/*.go
/project/api/*.go
If I cd into either engine or api, and run go test it works but not in the root folder.
cd /project
go test
? /project [no test files]
Is there anyway to run all tests from the root?

你可以使用 ...（省略号）运算符来测试当前包的所有子包。像这样：go test ./...。
如果你要做更复杂的操作，还有其他解决方案，比如使用 list 工具。像这样（例如）：go test $(go list ./... | grep [regex])。这对于排除 vendor 目录中的测试非常有用。
另外，你可能想了解一下 gt 命令，可以在这里找到：https://godoc.org/rsc.io/gt，并将缓存添加到 go test 命令中。
最后，不要犹豫阅读 https://blog.golang.org/cover，以获取有关在 Go 语言中进行代码覆盖分析的信息。
英文:
You can use the ... (ellipsis) operator to test all subpackages of the current package. Like that: go test ./....
There are other solutions that you might want to try later if you do something more sophisticated, like using the list tool. Like that (for example): go test $(go list ./... | grep [regex]). That's useful to exclude the vendor directory from your tests.
Another thing you may want to know about is the gt command that can be found here https://godoc.org/rsc.io/gt and add caching to the go test command.
Finally, don't hesitate to read https://blog.golang.org/cover to get informations about code-coverage analysis in golang.

我发现这个问题很烦人，当在项目根目录下运行go test ./...时，实际上会从pkg/pkg_name/文件夹运行。你可以通过在init()辅助函数中设置cwd来将测试设置为项目根目录。
我在这里找到了解决方案。你可以尝试在你的文件中使用以下代码片段：
func init() {
_, filename, _, _ := runtime.Caller(0)
dir := path.Join(path.Dir(filename), "../..") // 根据测试文件的位置进行更改
err := os.Chdir(dir)
if err != nil {
panic(err)
}
}
上面的代码片段适用于我在pkg/$name/$name_test.go中的测试。
英文:
I find this irritating that go test ./... when run from project root will actually run from pkg/pkg_name/ folder. There is a way you can set the tests to project root by setting cwd in the init() helper function.
I found the solution here You could try the following snippet in your _file:
func init() {
_, filename, _, _ := runtime.Caller(0)
dir := path.Join(path.Dir(filename), "../..") // change to suit test file location
err := os.Chdir(dir)
if err != nil {
panic(err)
}
}
This snippet above works for my tests in pkg/$name/$name_test.go.

只运行sudo go test -v ./...可能会失败，因为你可能没有为GO设置根环境，就像你设置非根环境一样。
你可以去重置根目录中的所有内容，或者执行以下简单步骤：
sudo -E go test -v ./...
这将以根用户身份运行，但保持你的环境设置。
英文:
just running sudo go test -v ./... will probably fail because you probably do not have your root environment setup for GO just like you set the non-root env.
You can go and reset everything in the root, or do this easy step:
sudo -E go test -v ./...
This will run as root but keep your env settings.
