英文:
go unit test runs from %APPDATA%
问题
我正在尝试使用"go test"运行一些我的Go单元测试，但测试可执行文件是从我的计算机的%APPDATA%/local/temp目录构建和运行的。我的计算机有IT强制执行，除了从预先批准的目录（即C:/dev/projects）运行之外，阻止运行任何未被识别的可执行文件。我的所有Go源代码都在那个目录中，包括我的*_test.go文件。有没有办法告诉Go测试模块从当前目录构建和运行？
英文:
I am trying to run some of my Go unit tests using "go test" but the test executable is built and run from my machine's %APPDATA%/local/temp directory. My PC has IT enforcement which blocks any unrecognized executable from being run other than from a pre-sanctioned directory (i.e C:/dev/projects"). All my Go source code are in that directory, including my *_test.go files. Is there a way to tell the Go test module to build and run from the current directory?

是的，你可以这样做。
在执行go test之前设置临时目录。默认情况下，临时目录环境变量的评估顺序为TMP、TEMP、USERPROFILE、Windows目录；请参考msdn文档。
基本上，它会在给定的临时目录下编译并执行go test。
C:\> cd dev\projects\src\mygotest
C:\dev\projects\src\mygotest>echo %CD%
C:\dev\projects\src\mygotest
C:\dev\projects\src\mygotest>set TMP=%CD%
C:\dev\projects\src\mygotest>go test -x

注意： TMP只在当前终端会话中设置，不会影响系统环境变量。
从上面的测试输出中需要注意的重要事项是WORK=C:\dev\projects\src\mygotest\go-build306298926。
祝你测试愉快！

Setting temp directory before executing the go test. By default temp directory environment variable gets evaluated in the order of TMP, TEMP, USERPROFILE, Windows directory; refer to msdn doc.
Basically it complies the go test under given temp directory and execute it.
C:\> cd dev\projects\src\mygotest
C:\dev\projects\src\mygotest>echo %CD%
C:\dev\projects\src\mygotest
C:\dev\projects\src\mygotest>set TMP=%CD%

Note: TMP set to current terminal session only, it doesn't affect system environment variable.
Important thing to note from above test output is WORK=C:\dev\projects\src\mygotest\go-build306298926.
Happy testing!
