This test consists of 2 parts:

• download-update.yaml
• verify-rollback.yaml
• verify-reboot.yaml

To confirm full rollback all 3 .yaml files need to be used in a test job. The DUT needs to reboot twice during the job. Therefore interactive shell is used as a part of the job. Example test job (testing part) below:
