Helpers for creating database tests with hspec and pg-transact
hspec-pg-transact utilizes tmp-postgres to automatically and connect to a temporary instance of postgres on a random port.
describeDB migrate "Query" $ itDB "work" $ do execute_ [sql| INSERT INTO things VALUES (‘me’) |] query_ [sql| SELECT name FROM things |] `shouldReturn` [Only "me"]
In the example above describeDB wraps describe with a beforeAll hook for creating a db and a afterAll hook for stopping a db.
Tests can be written with itDB which is wrapper around it that uses the passed in TestDB to run a db transaction automatically for the test.
The libary also provides a few other functions for more fine grained control over running transactions in tests.
