Forking in "go test"

[Christopher Lenart]

I am writing a library to start and manage child processes within a go program.

When attempting to test this with "go test", I always get fork/exec, permission denied error. If i modify the tests to be called from a main function as part of a main package and run it as a standalone program, it works just fine.

Does the go test program not allow forking? Do I have something configured wrong?

I am using the os/exec package, Run() in particular.

Update: I discovered that it will work, when the executable file being forked into is in the same directory as the go test.

That is an annoying restriction though..

I don't know if this is the issue, but note that using go test runs
the test program in a different, temporary, directory.

Is your /tmp mounted with the noexec flag ?
