I'm not a Librarian expert, but I think you want `project_path` to be the directory where the `Cheffile` lives. That being said, this is fine. The `chefspec/berkshelf` and `chefspec/librarian` plugins are designed for the "average" use case. If you are doing crazy stuff with multiple Cheffiles, you need to set that up on your own, because I don't want to cloud the beginner experience with complex use cases.
