DESCRIPTION
So you’ve probably heard how agile people like to burn documentation. They may declare “WORKING SOFTWARE don’t need no stinkin’ documentation.” But here’s a secret: They love testing. (Or at least they say they do ;). As a software tester you need to know about story testing (a.k.a acceptance test driven development). When done well, story testing empowers a team to increase collaboration between business, testing, design, and developers. Oh, and it creates valuable, living documentation. We all know communicating what ought be built is one of the hardest parts of making great software. Story tests give you: * An artifact for collaboration about what should be built * Feedback on how close to done your software is * Safety to know when a change breaks existing functionality In this workshop, you’ll discover: * What story testing is * How to write story tests that provide maximum communicative power with minimum brittleness * How to break user stories and minimum marketable features into story tests

Why?
• A Multitude of Perspectives Drives Out Uncertainty
• Collaboratively Determining Acceptance Criteria Shares Knowledge Faster Than a Handoff

Let’s Practice!
• Go to the story map nearest to you
• Start breaking the user tasks closest to the top down into scenarios
• Hint: There are no bad scenarios! Write collaboratively!
• In 15 minutes, we’ll reconvene and share

Better Scenarios
• Keep them to 1 Given, 1 When, and 1 Then
• Write at a user goal abstraction
• Don’t use “click/type/etc” You’re writing for a person! not a computer!
• Use your personas!
• More Scenarios the merrier! Survival of the Fittest!

Let’s Practice! (Again!)
• Go back to the story map nearest to you
• Write some more scenarios with your knew knowledge and feedback
• WRITE A BUNCH OF EM!
• In 15 minutes, we’ll reconvene.

Some Final Secrets
• Awesome developers can automate these story tests so that they slowly turn on as development continues.
• When written well, scenarios can be used as living reference documentation for your application
• Iterate and Adapt!
