+   The location of the main working directory of the job.

+
+   Arguments passed to chart testing.
+
+   The defaults are suitable for a Zuul environment because
+   `validate-maintainers` requires a valid git remote (which is not
+   present in Zuul) and `check-version-increment` requires each commit
+   to have a new version; Zuul users are expected to set the version
+   when tagging/publishing a release.
