- 4. Unit Testing Test driven development (TDD) encourages simple designs and inspires confidence. Tests define: • The expected behavior • What you want to achieve • What your program should do
- 5. The Code
- 6. The Test
- 8. Benefits There are numerous advantages: • You have an execution environment for running your code • You have a place to document business rules • Dramatically simplifies refactoring • Forces you to write smaller, less complex functions and methods
- 9. Benefits Write tests for failing code. • Problem is replicated and clearly described • Fix is proven by demonstration
- 10. Code Coverage Describes the degree in which a product is tested:
- 11. Tools Unit testing frameworks are available in almost any language: • PHP’s PHPUnit • Java’s JUnit • Ruby’s Test::Unit • iOS / Objective C (native) • Python’s unittest • .NET’s xUnit
- 12. Regression Testing Automated scripts or playback of recordings. • Verify changes don’t introduce unexpected faults • Monitor performance changes • Checks correctness of the program and its output • Interacts with the program as a user would
- 13. Selenium seleniumhq.org Open Source • Clicks links • Fills out forms • Scans for content • Runs in-browser • Interacts as a user would • WebDriver Compatible
- 15. Watir watir.com Open Source • Test with Ruby • Multi-browser (WebDriver) • Headless Mode • Connects to Databases • Measure Performance
- 16. Watir in Action
- 17. Load Testing Measure response times after simulating real traffic. • Ensure changes don’t impact performance • Determine hardware/network requirements • Expose bugs (race conditions) • Simulate customer behavior at scale
- 18. wget
- 19. Neustar
- 20. Usability Testing Evaluate your product using real users to: • Discover errors • Identify areas for improvement • Efficiency • Accuracy • Recall • Emotional Response
- 21. Hallway Testing Participants chosen from a random pool. Can be cost prohibitive for smaller companies.
