 When you run ALKiln on the command line, run the tests in the root directory of the docassemble package with the tests. There are other ways to tell processes where the root directory is. For example, ALKiP, a docassemble package that uses ALKiln inside an author's server, runs `subprocess.run()` or `subprocess.Popen()` with `cwd=`. In ALKiP the `cwd` is most likely `/tmp`.
