Technical Debt 2

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 16 Definition Technical Debt shortcuts purposely taken Bad things that plague systems Bad design Defects Insufficient test coverage Excessive manual testing Poor integration management Lack of platform experience • Naïve Debt • Unavoidable Debt • Strategic Debt § Activities to handle technical debt

Design 3

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 18 Patterns § Observer § Delegate § Factory

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 19 Simple Design Rules § Write Tests. Why? § Simple How? § Expressiveness. What? How? § Minimize items? Why?

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 20 Question A B

Structure 4

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 22 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?

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 23 DI, DOC, 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 ) { // .. } }

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 24 Question A) B)

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 25 Question A) B)

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 26 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 5

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 28 ADP, SDP, and SAP § Acyclic Dependency Principle (ADP) § Stable Dependency Principle (SDP) Where a dependency ends? § Stable Abstraction Principle (SAP) More stable, more abstract

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 30 Equations § Instability = Cout (Cin + Cout) § A = // Question: a package with 1 interface and 4 classes // implementing the interface. § D = A + I – 1

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 31 SDP ? in:0 out 2 in:1 out 2 in:1 out 0 in:2 out 1 in:1 out 0

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 32 SDP?

Javier Gonzalez-Sanchez | SER516 | Spring 2018 | 33 D?
