func LookPath

func LookPath(t testing.TB, file string) string

LookPath searches for an executable named file in the directories named by the PATH environment variable. If file contains a slash, it is tried directly and the PATH is not consulted. Otherwise, on success, the result is an absolute path.

In older versions of Go, LookPath could return a path relative to the current directory. As of Go 1.19, LookPath will instead return that path along with an error satisfying errors.Is(err, [ErrDot]). See the package documentation for more details.
