Presented at the Columbus ATDD Developers Group in April 2011 with Paul Bahler (@paulbahler) and Kevin Chivington from IGS Energy.

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
