jgs 00000001 Do NOT be a Grade Grubber § Grading is done applying the same policies to all students as described in the syllabus. § It is unethical to bring to your instructor's attention the possible impact of your course grade on your future plans, including graduation, scholarships, jobs, etc. Do not send requests to your instructor asking for a grade that you did not earn with your work.

jgs 00000001 Agenda § Sample Exam is available. Test your system ASAP § Midterm Exam available April 22 from 4:30 pm to 5:45 pm Key ideas: a) Show your environment. b) It is a CLOSED BOOK exam. Do not use any material c) Scratch paper is allowed. Empty White Paper. Show it on camera when you show your environment!

jgs 00000001 Note The following is a summary of the most relevant ideas. But the exam is not limited to these, i.e., The following IS NOT a comprehensive list

Agile Process 1

jgs 00000001 Review § Lecture: Background of process models (5); agile vs plan-based; what is and what is not “Agile”; agile manifesto; When to use agile and when is not a “good” option? Factors to be reviewed [Somerville 2,3] § Lecture: Requirement vs Task; Product backlog; sprint; agile process, ceremonies, and roles; burndown chart [Somerville 3,4] § Lecture: Agile principles (7) [Rubin 3] § Lecture: People factors (3); clean coding; clean code principles; [Martin 1] § Lecture: PBI; user story; epics; features; themes; [Rubin 5]

jgs 00000001 Review § Lecture: storyboard; epic vs story; INVEST; common errors [Rubin 5,6] § Lecture: Product backlog; DEEP; Planning Poker; Grooming; [Rubin 6] § Lecture: Sprint; Sprint characteristics; sprint planning; sprint backlog; [Rubin 4] § Lecture: KISS, DRY, Readable, Coding Guidelines for Java [Java] § Lecture: Estimation; Velocity; [Rubin 7]

Design 2

jgs 00000001 Simple Design Rules § Write Tests. Why? § Simple How? § Expressiveness. What? How? § Minimize items? Why?

jgs 00000001 Patterns § Observer § Delegate § Factory

Structure 3

jgs 00000001 Lecture 18 § Dependency Injection (DI) What is? How to implement it? § Separation of Concerns (SOC) What is? How to implement it? § Low Coupling What is? How to implement it?

jgs 00000001 DI, SOC, LC § public class Car { public Car () { engine = new Engine(); wheels = new Wheels[4]; seat = new Seats[4]; // .. } } § public class Car { public Car (Engine e, Wheels[] w, Seat[] s ) { // .. } }

jgs 00000001 Question A) B)

jgs 00000001 Question A) B)

jgs 00000001 Question § LOC per method? § CC per method? § Tangled (best value)? § Distance (best value)? § Is 0 the best value for A? § Is 0 the best value for I?

Metrics 4

jgs 00000001 ADP, SDP, and SAP § Acyclic Dependency Principle (ADP) § Stable Dependency Principle (SDP) Where a dependency ends? § Stable Abstraction Principle (SAP) More stable, more abstract

jgs 00000001 ADP ?

jgs 00000001 Equations § Instability = Cout (Cin + Cout) § A = // Question: a package with 1 interface and 4 classes // implementing the interface. § D = A + I – 1
