    Test case:
        Tag Retention
    Setup:
        Create Project test-retention
        Push image test1:1.0, test1:2.0, test1:3.0,latest, test2:1.0, test2:latest, test3:1.0, test4:1.0
    Test Steps:
        1. Create Retention Policy
        2. Add rule "For the repositories matching **, retain always with tags matching latest*"
        3. Add rule "For the repositories matching test3*, retain always with tags matching **"
        4. Dry run, check execution and tasks
        5. Real run, check images retained
    Tear Down:
        1. Delete project test-retention
