2. jgs Code Metrics
3. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 4 Metrics Size LOC eLOC lLOC Complexity Average, Max, Min LOC Cyclomatic Complexity Software Metrics
4. jgs Structural Metrics
5. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 6 Example A
6. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 7 Example B
7. jgs Abstractness
8. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 10 § Express the portion of contained abstract types. § It is a value 0 to 1: 0 (only concrete classes) to 1 (only interfaces and abstract classes) Abstractness of a Package
9. jgs Instability
10. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 12 § Indicates whether (a) the item is mainly used by others (stable – hard to change); or (b) it mainly depends on other items (instable – changeable). § It is a value between 0 and 1: 0 only incoming dependencies to 1 (only outgoing dependencies) Instability
11. jgs Distance
12. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 14 § Distance: how far a package is away from the Main Sequence § D = A + I – 1 § Values -1 to 1 § Absolute Distance |D| Distance
13. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 15 Stable Abstraction Principle Abstract concrete Stable Hard to Change Only incoming dependencies Unstable Changeable Only outgoing dependencies
14. jgs Test Yourselves
15. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 17 Question project3.common.model project3.client.UI project3.server.controller
16. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 18 Question
17. jgs Key Ideas
18. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 20 Project Presentation Product Process You
19. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 21 Demo of your project. Show your project running. First Act – Demo
20. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 22 Taiga à Stories, Backlogs, and Task board Stories (INVEST), Sprint backlog, product backlog. Estimation (story points) Talk about tasks; who is doing what? Everybody is doing some programming! Show and explain your Burndown Chart. Second Act – Your process
21. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 23 Show your class diagram. Use colors as needed (Single Responsibility Principle) What are the A, I, or D in the new class? (show the 2D plot regarding where your classes are in terms of the pain zone) Third Act – Software Design
22. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 24 Show US your GitHub Who is doing What? (everyone is adding or updating code) Show US your Code and Code Metrics Are your metrics OK (LOC, eLOC, lLOC, CC)? Any significant aspect that you want to share? Fourth Act – Code
23. jgs Javier Gonzalez-Sanchez | CSC 308 | Winter 2023 | 25 Review What is Good in the product? What is next for the product (next features to be added)? (your promise for the next sprint presentation) Retrospective (Process & People) What went well? What did not go well? Fifth Act – Review and Retrospective
