/// completes with the result of running the process, i.e., exit code, standard
/// out and standard in. Tests that there should be an error code which is not
/// zero (not success)and not 255 (not a runtime error) if invalid file path is
/// used - which is all we really know about the `dart` executable. Any other
/// error should be fine.
/// For dartkp configuration, exit code should be 255: VM initialization failed
/// because cannot load non-existing snapshot and runtime exception is thrown
/// here, so exit code should be 255 here.
