Testing

In the screenshot below, the two new jobs notification_job_failed and notification_job_success are added to the generated pipeline. As you can see, the "failed" job runs after the QA job failed.

Beside the existing notification when the stage starts, there is an addition notification when the stage finishes, which shows version and status.

In the following testing, you see the notification adapts accordingly to release version and job status.
