Testing - lecture 10

Defect testing

Defect testing - looking for problems with the codes behaviour

The idea is that you find so may bugs that there cant be many left

Validation testing

Validation testing - validating that the code meets the requirements

Four levels of tests

1. Unit tests - testing functions/methods in code
   - Good for test driven development

2. Integration tests - testing if multiple methods work together

3. System tests - testing the entire system, essentially end2end tests
   - looks at: security, scalability, installation, documentation, recoverability,
   load and stability

4. Acceptance tests - See what the real users think of the updates, might only hand it out to
   some people A/B testing (Alpha/Beta)
