In Scripted test you can add files to the steps and then you seem in the tests' run.
in BDD though, there are no steps. So if we need to attach files to the test, we just add it to the test itself.
The problem is that they're not seen in the run, so tester needs to go back to the test to see them.

Attachments should somehow be visible in the BDD Run, maybe above the scenario, with Run custom fields?
