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?
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.

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!
