The document discusses Test Driven Development (TDD) within the context of Sitecore, detailing its origins, cycles, and advantages. It covers different testing types like unit and integration tests, recommended tools, and methodologies, including demonstrations of Sitecore integration testing and the use of Sitecore Fake DB. The text highlights the benefits and challenges of implementing TDD, emphasizing the importance of community involvement and ongoing learning.

- 1. Organized by the Community, for the Community. TEST DRIVEN SITECORE Dan Solovay Sitecore MVP Lead Architect at XCentium
- 2. Organized by the Community, for the Community. OVERVIEW • What isTDD? • Unit or Integration tests? • Tools • Demo of Sitecore IntegrationTesting • Demo of Sitecore.FakeDB • Demo of Glass.Mapper + Autofac • How to get started withTDD? SUGCON NORTH AMERICA 2015 2
- 3. Organized by the Community, for the Community. MORE ISOLATION Sitecore Integration Testing Sitecore.FakeDB Glass.Mapper + Autofac SUGCON NORTH AMERICA 2015 3
- 4. Organized by the Community, for the Community. MORE FLEXIBILITY SUGCON NORTH AMERICA 2015 4
- 5. Organized by the Community, for the Community. SUGCON NORTH AMERICA 2015 5 TEST DRIVEN DEVELOPMENT
- 6. Organized by the Community, for the Community. AGILE ORIGINS OF TDD • Rediscovered by Kent Beck • Extreme Programming – Embrace change through continuous feedback • Popularized by Robert Martin – Author of SOLID principles – “What if your code always worked?” SUGCON NORTH AMERICA 2015 6
- 7. Organized by the Community, for the Community. THE TDD CYCLE • RED – Right just enough code to fail • GREEN – Right just enough code to pass • REFACTOR – Improve design when everything is working SUGCON NORTH AMERICA 2015 7
- 8. Organized by the Community, for the Community. SUGCON NORTH AMERICA 2015 8 UNIT AND INTEGRATION TESTING
- 9. Organized by the Community, for the Community. WHAT IS A UNIT TEST? • Automated • Full control / runs in memory • Consistent & fast • Tests a single logical concept • Readable & maintainable • Trustworthy SUGCON NORTH AMERICA 2015 9 Roy Osherove, Art of UnitTesting
- 10. Organized by the Community, for the Community. INTEGRATION TESTS • More fragile • Provide full system confidence • Shows different systems working together SUGCON NORTH AMERICA 2015 10
- 11. Organized by the Community, for the Community. SUGCON NORTH AMERICA 2015 11 TOOLS
- 12. Organized by the Community, for the Community. MYTOOLBOX • XUNIT – Better separation of tests than NUNIT. • NCRUNCH – Runs tests as you type. • NSUBSTITUTE – Creates fake versions of interfaces in tests. • AUTOFAC – Creates real versions in production. SUGCON NORTH AMERICA 2015 12
- 13. Organized by the Community, for the Community. SUGCON NORTH AMERICA 2015 13 TESTING SITECORE
- 14. Organized by the Community, for the Community. SITECORE INTEGRATION TESTING • Browser based – More robust – Http Context available • Class Library based – Works withTest Runners – Easier to automate SUGCON NORTH AMERICA 2015 14
- 15. Organized by the Community, for the Community. SITECORE FAKE DB • Developed by Sergey Shusliapin of Sitecore Ukraine • Uses Sitecore DLLs, replaces data layer • Tests Sitecore Items directly • No code changes required! SUGCON NORTH AMERICA 2015 15
- 16. Organized by the Community, for the Community. MAP SITECORE ITEMS • Use object mapper like Glass • Use Dependency Injector like Autofac • Your code does not talk directly to Sitecore SUGCON NORTH AMERICA 2015 16
- 17. Organized by the Community, for the Community. SUGCON NORTH AMERICA 2015 17 NEXT STEPS
- 18. Organized by the Community, for the Community. BENEFITS • Encourages focus • Creates confidence • Drives good design SUGCON NORTH AMERICA 2015 18
- 19. Organized by the Community, for the Community. CHALLENGES • Hard to learn new habits • Team buy in • Finding time SUGCON NORTH AMERICA 2015 19
- 20. Organized by the Community, for the Community. SOLUTIONS • Avoid all-or-nothing thinking – One, two hours ofTDD per week • Get involvement – Pair up, ask for input – Run aTDD Kata session • Sell the value – Fast feedback – Flexible design SUGCON NORTH AMERICA 2015 20
- 21. Organized by the Community, for the Community. FEARLESS If we have the tests we become fearless about making changes. If we see messy code, or an unclean structure, we can clean it without fear. Because of the tests, the code becomes malleable again. Because of the tests, software becomes soft again. – Robert Martin, bit.ly/tdd3rules SUGCON NORTH AMERICA 2015 21

Editor's Notes
- #14: Okay, let’s see how these concepts apply to Sitecore. First, let’s look at tests that actually execute logic against the Sitecore database, so Sitecore integration tests.
