testing - 为特定的操作系统或架构去测试文件

Question

在 Go 中，文件名具有语义。例如:

*_windows.go // Only include in compilations for Windows
*_unix.go    // Only include in compilations for Unix
*_386.go     // Only include in compilations for 386 systems
*_test.go    // Only include when run with `go test`

但是，我似乎无法让以下工作正常进行:

*_windows_test.go // Only include when running `go test` on windows
*_test_windows.go // Another attempt

这甚至可以用 Go 实现吗？如果是，怎么办？
