Some good questions to ask yourself
Monday, July 1, 13
• How often does it need to be checked (e.g. how often does it change)?
• How long does it take to test manually?
• How valuable is it (e.g. core functionality that is used heavily by our users, used by a prominent user group, legal or political, etc.)?
• How risky is the feature (e.g. fundamental back-end changes, complex architecture, large user facing impact)?
• What is the level of effort to automate (S, M, L, XL)?
• Does it involve look and feel?
Monday, July 1, 13
• Where does the business logic live?
• How is it architected?
• What kind of test coverage exists already?

BDD Lessons Learned
• Writing good gherkin is difficult
• If you plan to change behavior, change one thing at a time
• Top down doesn’t matter as much as bottom up
• Ask good questions
