Study Notes
Software Development Team Roles
- Requirements Engineer: Critical link between client and IT team; also known as Business Analyst or Product Owner
- Product Owner: Gathers client requirements, documents them as product backlog and user stories to ensure customer needs are met
- UI (User Interface): Represents visual elements of application users interact with
- UX (User Experience): Focuses on overall design and usability; UX design informs creation of test scenarios and cases. Software testers validate
- Front-End Developer: Converts UI designs into functional code forming the visible part of an application
- Full-Stack Developer: Handles front-end and back-end development, bridging client-side and server-side operations.
- Native Application Developer: Develops applications specific to operating systems (Android or iOS) to ensure optimal performance
- Project Manager: Oversees project schedule, allocates time for each phase including testing and resolves team conflicts (between developers and testers) related to defects
- Scrum Master: Facilitates communication between team members
Software Development Lifecycle Models (SDLC)
-
Sequential Development: Strict sequence of steps; once a step completes, there is no going back.
-
Phases: Analysis, Design, Implementation
-
Analysis: Led by Requirements Engineer/Product Owner; writes specifications (SRS or PRD) or user stories
-
Design: UI design, database schemas, and other system designs are created
-
Implementation: Developers write code and begin testing
-
Waterfall Model: Linear and rigid phases.
-
Phases: Requirements, Design, Development, Testing, Deployment, Maintenance
-
Drawbacks: Testing occurs late, making early issue identification difficult; less favored by modern companies
-
V-Model: Similar to Waterfall, emphasizing early testing.
-
Testing activities are planned in parallel with corresponding development phases
-
Agile Software Development: Focuses on early and continuous customer feedback for iterative development.
-
Incremental Development: Delivers small, functional increments of the product over time
-
Iterative Development: Develops the product in cycles; refining with every iteration based on feedback
-
Scrum: Agile framework with iterative sprints, daily stand-ups, and regular reviews to ensure product aligns with client expectations
Basic Concepts of Software Testing
-
Definition of Software Testing: Method to evaluate software quality, reducing operational failures. Involves various activities throughout the development lifecycle, not just test execution.
-
Types of Software Testing
-
Dynamic Testing: Executes code; inputs produced outputs
-
Static Testing: Does not execute code; reviews (white-box tests) support early testing
-
Categories of Software Testing
-
Validation: Ensures product meets customer requirements
-
Verification: Confirms the product is built correctly according to design specifications
-
Objectives of Testing: Identify and fix defects, meet quality standards, and ensure intended functionality across various scenarios
-
Testing and Debugging
-
Testing: Identifies defects/failures in software
-
Debugging: Locates and fixes the cause of detected defects
-
Confirmation Testing (Retesting): Repeats steps that caused a defect to confirm resolution
Test Process
- Steps for developing and testing software effectively
- Test processes activities: Testing planning, Monitoring & Control, Analysis, Design, Implementation, Execution, Completion
Test Levels
- Test levels: Organized groups of test activities
- Each test level is an instance of the test process
- Test levels are related to other activities within the software development lifecycle
- Component Testing: Tests individual components/units of software
- Integration Testing: Validates interactions between integrated components/systems
- System Testing: Verifies the entire system meets requirements
- Acceptance Testing: Ensures the product satisfies customer needs and is ready to deploy
- Alpha Testing: Conducted in-house by development team
- Beta Testing: Performed by end-users in real-world environment
Testing Types
- Functional Testing: Validates software functionality against requirements
- Tests what the system does; usually answered as Yes/No
- Non-Functional Testing: Assesses aspects like performance, usability, and security
- Testing how the system performs; Hard to answer with Yes/No; Measured as a range
- Black-Box Testing: Focuses on inputs and outputs without considering internal code structure
- White-Box Testing: Involves reviewing the internal code structure and design; Tests while monitoring the internal structure
- Dynamic Testing: Involves executing the code
Additional Testing Types
- Retesting (Confirmation Testing): Verifies previously identified defects are fixed
- Regression Testing: Ensures that recent changes have not impacted existing functionality
- Smoke Testing: Preliminary test to verify basic functionality; checks if main functionalities of the build allow for further testing.
