Description

Currently the test uses a test persister, which mocks the persister we use in the handler. But it does not provides all functionality to test the handler completely and it is hard to maintain.

Describe your ideal solution

Change the test, that need a database, to integration tests, using github.com/ory/dockertest. One handler test is already using it, check it out: user_test.go.

If a test needs a database, it should be skipped if the -short flag is provided. So even if someone has no docker installed, he can run some tests.
