I generally default to composition, which is what you've seen throughout the course. Simply because I find loose coupling easier to maintain long-term. But inheritance might be a useful decision, so let's have a look at a base test approach. A common inheritance mechanism people use is the base test, Which makes sense when all the tests are GUI tests working on the same application, why not have a base object that all the tests extend?
