    8) Code Review - CS2800 - Software Engineering

    This document, "Modern Code Review for Improving Software Quality", explores contemporary code review practices, examining their effectiveness in addressing coding convention violations. It presents research investigating the prevalence of convention violations despite reviews, the types of violations tackled, and their impact on the review process. The text also discusses the potential benefits of recommending related prior code reviews to provide valuable context for reviewers. Furthermore, it outlines requirements for effective similarity measurements to facilitate such recommendations, comparing different approaches. The research ultimately aims to understand and enhance the role of code review in software development.

    7) Testing Concepts - CS2800 - Software Engineering

    This resource explains fundamental software testing concepts, starting with program flow, which dictates execution order and is visually represented by flowcharts and control flow graphs. It introduces cyclomatic complexity as a metric to quantify a program's logical difficulty based on its control flow. The material then discusses test coverage, outlining criteria like statement, branch, and basic condition coverage to assess the extent to which tests exercise the codebase. Ultimately, the document bridges the understanding of program complexity with strategies for ensuring adequate test coverage.

    6) Lifecycle - CS2800 - Software Engineering

    This collection of materials outlines the Software Development Lifecycle and introduces Agile methodologies, with a strong focus on the Scrum framework. It begins by contrasting traditional approaches with the values expressed in the Agile Manifesto, emphasising individuals, working software, collaboration, and responding to change. The documents then detail the Scrum process, including roles like the Product Owner, Scrum Master, and Developers, and its structured workflow involving Sprints, the Product Backlog, and various meetings such as Sprint Planning, Daily Scrums, and Sprint Reviews. Key Scrum concepts like timeboxing, increments of value, and the importance of honesty and continuous improvement are highlighted. Furthermore, the materials provide context for a team project utilising Scrum principles, outlining the sprint structure and expectations.

    5) Refactoring - CS2800 - Software Engineering

    These sources comprehensively outline refactoring, the systematic improvement of code without altering its functionality, emphasizing its importance in combating technical debt, which arises from poor coding practices and rushed development. The materials detail code smells, indicators of underlying problems in code categorized as bloaters, object-orientation abusers, change preventers, dispensables, and couplers, and provide numerous examples of each. Furthermore, the resources present various refactoring techniques, categorized by composing methods, moving features, organising data, simplifying conditionals, simplifying method calls, and dealing with generalisation, illustrating their application with before-and-after code examples. Finally, the sources discuss when and how to refactor effectively, including the use of automated tools for detecting code smells and the critical role of testing throughout the refactoring process to ensure code reliability.

    4) Design Patterns - CS2800 - Software Engineering

    These materials from lecture slides cover design patterns, which are reusable solutions to common software design challenges. The initial set of slides introduces the motivation and classification of these patterns, categorising them as creational, behavioral, and structural. Specific patterns like Singleton and Factory (both abstract and regular) within the creational category are detailed, alongside behavioral patterns such as Observer and State. The subsequent slides continue by examining structural patterns like Facade and Bridge, which focus on object composition, and conclude with an overview of the Model-View-Controller (MVC) architectural pattern, emphasising its role in separating concerns within an application.

    3) UML - CS2800 - Software Engineering

    This material introduces Unified Modelling Language (UML) as a graphical tool for software system design and communication, highlighting the class diagram as a frequently used type for outlining classes and their relationships. It then transitions to software design principles, including SOLID, emphasizing concepts like separation of concerns and avoiding repetition, while noting these are guidelines rather than strict rules. Finally, the text introduces the Spring Framework, an enterprise Java platform, covering its core features like Dependency Injection and Data Access Objects, and explains how to handle web requests and perform testing using Spring Boot and MockMvc.

    2) Maintainable Code - CS2800 - Software Engineering

    These sources present essential practices for developing maintainable software, particularly within a Java environment. They introduce key tools and libraries such as Maven for build automation, JUnit for unit testing, and static analysis tools like Checkstyle and SpotBugs for code quality. The materials emphasise the importance of writing well-documented code using Javadoc and following established coding standards to ensure consistency. Furthermore, they outline the principles of Test-Driven Development (TDD) and the benefits of Continuous Integration (CI) and Continuous Deployment (CD) pipelines for automated validation and deployment. Finally, the sources cover collaborative aspects of software development, including issue tracking and the code review process.

    1) Version Control - CS2800 - Software Engineering

    This material introduces the Version Control System (VCS), explaining its purpose in tracking file changes and enabling team collaboration on code, configurations, and documentation. It distinguishes between centralised (like SVN) and distributed (like Git and Mercurial) VCS, highlighting the advantages of the latter in terms of scalability and flexibility. The resource focuses extensively on Git, detailing its snapshot-based approach, local operations, file lifecycle, and the significance of commits, branching, and merging, including how to handle conflicts. Finally, it touches upon remote repositories, the role of platforms like GitLab for hosting and collaboration, and recommends resources for further learning about Git.
