10. Pros:
    ● More tests
    ● More testable code
    ● Discover missing
    requirements sooner
    ● Uncover novel designs
    ● Increased quality
    ● Refactor/add on with
    confidence
    ● Doesn’t generally take
    more time
    ● May start conversations
    Cons:
    ● First time setup of test
    framework takes extra
    time
    ● Not always practical (if
    requirements are not
    well defined)
    ● Makes changing object
    model harder
    ● May start conversations
