Previous Lectures
- Introduction on Bugs
- Why look for bugs? What are bugs?
- Where they come from? How to detect them?
- Refactoring
- What it is? Why you need it? How to perform it?
- Example Interactive Testing Session
- TriTyp Given three integers for the lengths of
the sides of a triangle, find the type of
triangle - Testing fun/hard? Terminology? Testing goal?

Coverage Criteria
- Did we have any test plan or purpose?
- Did we specify any test requirements?
- How good are our tests?
- Did we generate enough tests?
- Criterion rule that imposes test requirements
- Coverage satisfaction of test requirements
5
Why JUnit (or a Similar Tool)?
- We want to test (early and often)
- Automated testing
- Regression testing
- Alternatives have some cons
- Different language for scripting
- A lot of printing if no checking of result
- Using main does not compose well

Todays Lecture Coverage
- Statement coverage

Problem Set 1
- Will go out this week
- Four problems on Chapter 1 and JUnit

- Total of 120 points, but you need only 100 for
maximum score - Grading will be strict!
- Prioritize your work
