We're trying to move all the tests in the `framework/test/integrationtest` project into `framework/src/integration-test/src/test/scala/it/`, this puts them much closer to the code they are testing (same SBT project), making it easier to run them/quicker dev loops etc.  It also allows you to define actions that the tests use directly in the test.

You can have a look at `RequestBodyHandlingSpec` for an example of such a test.  Or the CSRFFilterSpec (which lives in the filters helpers project).
