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.
