What they are checking: Whether they use fault injection to check safe behavior.

How do you decide what to automate in testing and what to leave manual?

What they are checking: Whether they think about regression value, stability and cost of automation.

What do you look for when peer reviewing someone else's software or test scripts?

What they are checking: Whether they review for correctness, coverage and maintainability.
