  3. The Problem with Agility

  4. We are trying to “productize” our approaches...again.

  5. We are trying to “productize” our approaches...again.

  6. Fundamentally agile is about approaching the work in a different way.

  7. We need thinking business analysts

  8. 12

  9. We’re not building a house...

  10. We’re cleaning the house...

  11. It’s NOT easy • It is MUCH easier to slice up a backlog horizontally • Developers want to work horizontally (efficiency argument) http://simpleprogrammer.com/2011/11/21/understanding-the-vertical-slice/

  12. http://www.deltamatrix.com/2012-04-17-04-37-50/horizontal-and-vertical-user-stories-slicing-the-cakehttp://www.deltamatrix.com/2012-04-17-04-37-50/horizontal-and-vertical-user-stories-slicing-the-cake

  13. Why vertical slices? • It is about delivering working functionality as soon as possible. • Feedback.

  14. http://www.deltamatrix.com/2012-04-17-04-37-50/horizontal-and-vertical-user-stories-slicing-the-cakehttp://www.deltamatrix.com/2012-04-17-04-37-50/horizontal-and-vertical-user-stories-slicing-the-cake

  15. Why Behavior Driven Design • Work is done from the perspective of the user • Can slice vertically but narrowly • Tests behavior of the system • Executable requirements • Need to move as fast • as business • Appropriate feedback loop • Manual regression is • EXPENSIVE

  16. Acceptance Tests vs. Unit and Integration Tests

  17. Acceptance Tests vs. Unit and Integration Tests • Unit Tests confirm that you built it right (INSIDE OUT) • Acceptance Tests confirm that you build the right thing (OUTSIDE IN)

  18. Benefits • Implementing changes more efficiently • Quick feedback • Higher product quality • Less rework • Better work alignment to priority • (not just for agile teams)

  19. Describes how software should behave in plain text • Gherkin • Usable in many different human languages • Features can be written and understood by both non/technical project members • Not a replacement for unit testing; it’s not a low level testing/spec framework • Easy to execute in Continuous Integration environment (except MS TFS)

  20. Technology Stack • Cucumber - Domain Specification • Ruby, JRuby or .NET - map cukes to application • UI testing framework - Watir, Watin, Selenium, Capybara (headless), anything that supports WebDriver • Open source • STRONG community support

  21. Who’s Using the System What are they doing? Why do they care? Features

  22. Scenarios • Features are defined by one or more scenarios • Sequence of steps thru the feature that exercises on path • Use BDD style – given-when-then • Scenario: <description> • <step 1> • … • <step 2>

  23. Given - Sets up preconditions, or context, for the scenario • When - The action, or behavior, that we’re focused on • Then - Checks post-conditions and verifies that the right thing happened in the When stage Scenarios
