 As @stephen-soltesz pointed in out in a ticket:

 > Also, I recall a discussion in Berlin about validation of uploaded
 reports; specifically, at the time of report upload, it is necessary to
 determine that the "expected test-helper" and the "used test-helper" are
 the same type. This helps eliminate false-positives due to report errors
 caused by mismatches between the test-helper expected and used. This
 validation requires that the report is uploaded to the collector co-
 located with the test helper. Can testdecks be created to support the
 above?

 The hard part of doing this is making the collector speak to the test
 helpers. In other words to detect that the expected test helper is not the
 one used, we have to has the test helper that the user is supposed to be
 using if they have seen those requests from our user.
