Study Notes
Software Review and Inspection
- Software inspections are crucial for improving code quality and reducing defects in software development
- Inspections evaluate software quality and apply best practices to enhance team collaboration
- Students will gain skills to identify issues early and contribute to project success
Learning Objectives
- Perform software inspections to find defects early
- Use best practices for effective code reviews
- Assess software quality based on key characteristics
Software Review and Inspection - Pre-test
- A quiz to assess initial knowledge about software review and inspection
- Multiple choice questions were presented in the pre and post tests
Software Review
- Software review is a crucial part of SDLC
- Validates software's quality, functionality, and features
- Involves testing the software to ensure it meets client requirements
- A systematic examination of documents (requirements, designs, codes, test plans, test cases) by individuals
- Identifies and resolves errors early in the Software Development Life Cycle (SDLC)
- Typically performed manually
Process of Software Review
- Consists of stages including:
- Entry Evaluation
- Management Preparation
- Review Planning
- Preparation
- Examination and Exit Evaluation
Types of Software Review
-
Software Peer Review: Assesses the technical content and quality of a product, usually conducted by the author and other developers.
-
Types of Peer Reviews
- Code Review : Examines computer source code systematically.
- Pair Programming : Two developers write code together.
- Walkthroughs: Team members guide and comment on defects
- Technical Review : Highly qualified individuals examine the code for client use based on specifications and standards
- Inspection meetings: defined process used identify defects
-
Software Management Review: Evaluates work status; decisions regarding downstream activities are made.
-
Software Audit Review: An external review where independent critics inspect the software product.
Software Inspection
- Developed by IBM in the early 1970s to improve software quality beyond testing alone.
- Aims to identify and efficiently remove defects in code
- A structured review process that is more formal than peer reviews and walkthroughs
- The inspection process includes an entry criterion to prevent incomplete products from entering the process.
- Inspection process is developed, extended, and revised in the mid-1970s
Stages of Software Inspection
- Planning: Moderator plans inspection
- Overview Meeting: Author describes the background
- Preparation: Inspectors identify potential defects
- Inspection Meeting: Reader examines and inspectors identify faults
- Rework: Revisions of work product based on feedback
- Follow Up: Changes are verified
Code Reviewing and Inspection Techniques
- Objective: Reduce the cost of quality by finding and removing defects early
- Defects caught early reduce compound bugs
- Software quality has user and developer perspectives
- Quality characteristics from the user perspective are correctness, usability, reliability, security, and adaptability.
- Quality characteristics from developer perspective include maintainability, portability, readability, understandability, and testability
- Reviews are key parts of software quality assurance, including testing, debugging, and static analysis
Walkthroughs, Review and Inspections
- Walkthroughs are the least formal type of review, typically used for small changes
- Involves the author and reviewers
- Code reviews are more formal, often involving more than three attendees
- Code reviews are needed when substantial changes are made to a program
Code Inspection
- Most formal review meeting used to identify defects in work products
- Use checklists of common errors
- Reviewers prepare in advance for detailed inspection
- Specific rules regarding preparation, number of lines per review, duration of the meeting, and preparation are needed
Inspection Roles
- Moderator: Organizes inspection and materials
- Author: Provides materials and explains overall design
- Reader: Summarizes and understands the code
- Reviewers: Identify defects and raise questions
- Recorder: Records defects found during the meeting
- Managers are not allowed
Inspection Procedures
- Planning: Moderator sets up and schedules, author provides code, and scope of review.
- Overview Meeting (optional): Used if participants are unfamiliar, author presents overview
- Preparation: Reviewers study the code for potential defects.
- Inspection Meeting: Identification of defects, discussion, and potential solutions.
- Rework: Fixes for defects and code changes
- Follow-Up: Moderator verifies all changes
Modern Code Review
- A lightweight approach to code inspections
- Manual assessment of source code by humans to identify defects, mainly in industry and open-source software
- Code reviews can be done in multiple ways, include through email, pair programming, or with tools
- Tool-assisted code review is regarded as an efficient way to review code
