Does GoLang use reserved filenames?
问题
在CI/CD流水线中，我们有一个Go脚本，在构建可交付的构件之前进行一些预处理。如果我将脚本命名为main.go，在Go语言世界中是否算是不好的做法？我不明白是否有任何与脚本的实际文件名相关的命名空间问题。
我知道main.go是脚本，main_test.go是单元测试，所以我有些担心并正在寻求指导。
例如，如果我在shell（MacOS bash）中执行以下命令：go test
这将执行main.go脚本的单元测试，这让我相信main可能是某种保留的文件名。不过我可能错了。
你有什么想法？
英文:
In a CI/CD pipeline, we have a Go script that does some preprocessing prior to actually building our deliverable artifacts. If I name the script main.go is that a foul in the GoLang world or is that OK? I do not understand if there are any namespace concerns that tie back to the actual filename of the script.
I know that main.go being the script, main_test.go is the Unit Tests so I am leary and looking for guidance.
For example, if I execute from the shell (MacOS bash) the following: go test
This executes the unit tests for the main.go script which leads me to believe that main is some sort of reserved file name. I could easily be wrong though.
Thoughts?

文件名main.go并没有特殊含义。
Go会检测文件是否属于测试文件，是因为文件名以_test.go结尾，并且会检测包是否为可执行文件（而不是库），是因为包名为main（也就是以package main开头）。你可以在库中使用名为main.go的文件。
你可以在go/build的源代码中看到go build在文件中寻找的内容。它只检查了_test后缀，代码如下：
isTest := strings.HasSuffix(name, "_test.go")
英文:
The filename main.go is not special.
Go detects that a file is part of a test because it ends in _test.go, and detects that a package is a binary (instead of a library) because the package name is main (in other words, it starts with package main). You can use a file named main.go in a library.
You can see in the source code for go/build what go build looks for in files. It only has a check for the _test suffix, here:
isTest := strings.HasSuffix(name, "_test.go")
