Test data clean-up only applies to test data created using the 'Given I have created' binding

[ewingjm]

Records created during the When step block are missed from the current test teardown. It is unlikely that we'll achieve the ability to clean-up 100% of the records created during test execution (e.g. some may be created by processes rather than saving a form), but we should be able to either update our bindings that save a main form or quick create to capture these records.
