6. What is testing? Any ideas?
7. "Testing means checking it works" Source: a younger, less experienced me.
8. Software testing can be stated as the process of validating and verifying that a software program/application/product: 1. meets the requirements that guided its design and development; 2. works as expected; and 3. can be implemented with the same characteristics. http://en.wikipedia.org/wiki/Software_testing
9. Validation: Are we building the software right?
10. Verification: Are we building the right software?
11. Validation: • Unit testing • Component testing • Integration testing • Performance testing • Load testing • Security testing
12. Verification: • Functional testing • Exploratory testing • Usability testing • Acceptance testing • Prototypes • Simulations
13. Functional Tests Prototypes Simulations Exploratory Tests Usability Tests Acceptance Tests Performance Tests Load Tests Security Tests Unit Tests Component Tests Integration Tests Business-Facing Technology-Facing Support the Team Critique the Product

15. Functional Tests Prototypes Simulations Performance Tests Security Tests Manual & Automated Business-facing Tests against specification Mock-ups and prototypes
16. Exploratory Tests Usability Tests Acceptance Tests Unit Tests Component Tests Integration Tests Manual Business-facing Critique the product Elicit feedback
17. Unit Tests Component Tests Integration Tests Manual & Automated Technology-facing Critique the product Often overlooked! Performance Tests Load Tests Security Tests
18. Exploratory Tests Usability Tests Acceptance Tests Performance Tests Security Tests Unit Tests Component Tests Integration Tests Automated Technology-facing Support the team Internal quality checking!
19. Time for a break?
