1. An ATDD Case Study
2. So what’s the problem?
3. Acceptance Criteria Given I am a logged in user When I go to the final checkout page Then I should see the total cost of the order broken down by product cost, tax, and shipping charges And I should see the total cost of the order
4. The 3 Amigos
6. The 3 Amigos “…it’s like delivering a baby.”
7. Feature: Process an order Given I am a logged in user When I go to the final checkout page Then I should see the total cost of the order broken down by product cost, tax, and shipping charges And I should see the total cost of the order • Order total = total cost of products on the order + tax + shipping charges • Tax: – Ohio = 7% – Michigan = 6.5% – Other states = 0% • Shipping: – If total cost of products (before tax >= $25), shipping is free, otherwise $5
8. Definition of Done
9. The Board
10. What happens when testing isn’t included in your definition of done “Before”
11. What happens when testing IS included in your definition of done “After”
12. Who Writes the Tests
13. Co-location
14. “The Pod”
15. Open workspace
16. Continuous Integration
17. Reasonably Thorough Requirements "Walking on water and developing software from a specification are easy if both are frozen." ~ Edward V. Berard
18. Project Management • Self-directed teams • Everyone is responsible • PMs lay out the roadmap • Shared risk with the business • Risk based testing
19. An Incremental Process
20. Why work incrementally towards continuous improvement?
21. We’re not there yet… • Continuous improvement across teams • Better involvement with business sponsors • More visibility of continuous integration build • 75% of test cases automated in 2012
