从％APPDATA％运行单元测试

Question

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?

Answer 1

Yes you can.

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%

C:\dev\projects\src\mygotest>go test -x

Hello, playground

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!
