Please take a look at this scenario. If we have a SaaS system with a cloud server running in AWS, and some IOT sensors deployed on prem at the customer sites, and you are asked to test the entire system to ensure they work properly, before the system can be deployed at a real customer and go live. Can you describe how you would complete this task? Please try to give as much details as you could. It’s ok to branch off to talk a little about the approach, e.g. How would you work with developers to resolve issues found in your testing?
