##### SUMMARY
Both in the overview (see f.ex. https://app.shippable.com/github/ansible/ansible/runs/175858/summary/console) nor in the detail view for failed tests (https://app.shippable.com/github/ansible/ansible/runs/175858/82/tests) anything is shown.

This is only the case for ansible-test for `devel` when using the `integration` subcommand. `sanity` and `units` work fine.

##### ISSUE TYPE
- Bug Report

ansible-test
