When we run `go test` (without package param) it doesn't redirect
os.Stdout, so it's possible to detect is it a TTY and enable color output:
unix.IoctlGetTermios(int(os.Stdout.Fd()), ioctlReadTermios)
But when we run `go test .` (with package param) it does redirect
os.Stdout, so it's

released as https://metacpan.org/pod/DBIx::SecureCGI. Nowadays I suppose
best way to do something like this is using GraphQL (for ex.
