I actually had to use a similar hack there due to the limitation that go test compilates cannot spawn themselves where I needed to have an environment variable

  On Linux, "self" is /proc/self/exe. In general, I've seen people use `os.Args[0]`. But on checking again, I see there's even `os.Executable()` (https://pkg.go.dev/os#Executable https://pkg.go.dev/os#Executable) for this purpose. I'm quite sure go test compilates can spawn themselves, I'm doing it on many platforms. But, the test setup I was referring to was explicitly not that: the tests are spawning the main binary, not themselves. Using bazel+runfiles this is pretty easy to do. With the pure Go build tool, I'm not sure what approach I'd use to "guarantee" that I get a binary build for the same environment as the test.
