Study Notes

CASE (Computer Aided Software Engineering)

Application of computer-assisted tools and methods in software development to ensure high-quality and defect-free software
Includes tools such as profilers, debuggers, and code analyzers

Software Development Methodologies

Traditional (Monumental or Waterfall) Methodologies: sequential phases with no overlap
Agile or Lightweight Methodologies:
- Emphasize adaptability and responding quickly to change
- Reduce risk and validation errors
- Examples: XP (Extreme Programming), SCRUM

Agile Methodologies

Characteristics:
- Adaptability
- Ability to respond quickly to change
- Risk reduction
- Less chance of validation errors
Values:
- Customer feedback
- Code-centricity
- Documentation and modeling (but not as important as the software itself)

Naming Conventions

Self-documenting names: using long, meaningful names
Comments: explain code functionality
TODO comments: notes for developers to complete tasks

SCRUM

Agile approach
Sprint: each iteration of software development
Phase requirements: each phase requires a set of tests
Integrated testing: testing is integrated into each phase

eXtreme Programming (XP)

General features:
- Agile or lightweight methodology
- Human-centric development
- Controversial approach
Overview:
- Focus on coding as the main task
- Emphasis on continuous and automated testing
- Continuous integration (building a complete system copy several times a day)
- Design evolves throughout the project

The 12 Commandments of XP

Testing: key practice, automated, and ensures code functionality
Continuous Integration: building and testing a complete system copy several times a day
Refactoring: restructuring internal code structure without changing behavior
40-Hour Work Week: maintain a sustainable work pace
Small Releases: frequent, incremental releases
Simple Design: prioritize simplicity in design
Pair Programming: collaborative coding with regular role switching
Collective Ownership: shared responsibility for code
On-Site Customer: customer involvement in the development process
Metaphor: conceptual framework for understanding the system
Coding Standards: consistency in coding style
No unnecessary features: avoid unnecessary complexity

Pair Programming

Roles: Driver (writes code) and Observer (reviews code and makes suggestions)
Role switching: regular switching of roles between Driver and Observer

XP and SCRUM

Compatibility: XP and SCRUM can work well together

Principles

KISS (Keep It Simple Stupid): prioritize simplicity
YAGNI (You Ain't Gonna Need It): avoid adding unnecessary features or complexity

Automated Testing and Continuous Integration

Automated Testing: continuous validation of software functionality
Types of Automated Testing: Unit Testing, Integration Testing, etc.

Reality Check

Challenges: some non-functional requirements can be difficult to test for (e.g., ease of use)
Security: some security aspects can be tested for (e.g., port scanning)
