STDCI build summary to write message when no threads were found --------------------------------------------------------------- Key: OVIRT-2172 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2172 Project: oVirt - virtualization made easy Issue Type: New Feature Components: Standard CI (Pipelines) Reporter: Daniel Belenky Assignee: infra As an STDCI user I want to see a dedicated message at STDCI build summary that warns me that no threads were executed for my build to prevent cases where I think something runs while it doesn't (currently it shows blank page - users can think it's a bug in the summary.)
