Study Notes
Software Engineering Fundamentals
- Software engineering is an engineering discipline that provides knowledge, tools, and methods for defining software requirements, performing software design, software construction, software modeling, software testing, and software maintenance tasks.
- It aims to produce an efficient and reliable software product.
Importance of Software Engineering
- Important decisions are made during requirements analysis and design.
- Coding is only 20% of the project activities, while documentation, testing, integration, and maintenance are often overlooked.
Software Verification and Testing
- Software verification checks whether the developed software conforms to the requirements.
- It is performed by Software Quality Assurance Engineers (QA).
- Two approaches: formal reviews and inspections, and different kinds of testing.
- Testing aims to find defects (bugs) and cannot certify their absence, only decrease their rates.
Testing Process
- Test planning: establishing test strategy and test plan during requirements and design phases.
- Test development: creating test procedures, test scenarios, test cases, and test scripts.
- Test execution and reporting.
- Retesting defects.
Test Plan and Test Cases
- A test plan is a formal document that describes how tests will be performed.
- It includes a list of test activities, features to be tested, testing approach, schedule, and acceptance criteria.
- Test scenarios and test cases: stories to be tested and tests of single functions.
Software Construction
- During this phase, developers create the software.
- It includes internal method design, writing code, writing unit tests, debugging, and integration.
Writing the Code
- Coding is the process of writing the programming code (source code).
- The code strictly follows the design.
- Developers perform internal method design as part of coding.
Testing the Code
- Testing checks whether the developed software conforms to the requirements.
- Developers test the code after writing it, and unit testing is done by developers.
Debugging
- Debugging aims to find the source of an identified defect and fix it.
- Performed by developers.
- Steps: find the defect, identify the source of the problem, fix the defect, and test to check the fix.
Integration
- Integration is putting all pieces together, compiling, running, and deploying modules as a single system.
- Testing identifies defects, and integration strategies include big bang, top-down, and bottom-up.
Extreme Programming (XP)
- An agile method that takes an ‘extreme’ approach to iterative development.
- Practices: incremental planning, small releases, simple design, test-first development, and refactoring.
Agile Method: Scrum
- A general agile method focusing on managing iterative development.
- Three phases: sprint planning, daily Scrum, and sprint review.
The Agile Manifesto
- Prioritizes customer satisfaction through early and continuous delivery of valuable software.
- Values: working software over comprehensive documentation, customer collaboration over contract negotiation, individuals and interactions over processes and tools, and responding to change over following a plan.
