+Module     : Spec.Governor
+Maintainer : connor@mlabs.city
+Description: Tests for Agora governor.
+
+Thie module exports `specs`, a list of `TestTree`s, which ensure
+that Agora's governor component workds as intended.
+
+Tests should pass when the validator or policy is given one of the
+valid script contexts, which are defined in 'Agora.Sample.Governor'.
+
+TODO: Add negative test cases, see [#76](https://github.com/Liqwid-Labs/agora/issues/76).
