Scrum Testing Methodology¶
Overview¶
Scrum is an Agile framework that organizes work into fixed-length iterations called sprints. Testing in Scrum is integrated throughout the sprint, with testers being full members of the cross-functional Scrum team.
Scrum Framework Basics¶
Scrum Roles¶
Product Owner¶
- Defines product vision
- Manages product backlog
- Prioritizes features
- Clarifies requirements
- Accepts completed work
Scrum Master¶
- Facilitates Scrum ceremonies
- Removes impediments
- Coaches the team
- Protects team from distractions
- Ensures Scrum practices
Development Team (includes Testers)¶
- Cross-functional and self-organizing
- Delivers working software
- Shares responsibility for quality
- Collaborates continuously
- Typically 5-9 members
Scrum Artifacts¶
Product Backlog¶
- Prioritized list of features/user stories
- Maintained by Product Owner
- Continuously refined
- Includes acceptance criteria
Sprint Backlog¶
- User stories committed for current sprint
- Task breakdown
- Estimated effort
- Updated daily
Increment¶
- Working software at sprint end
- Potentially shippable
- Meets Definition of Done
- Demonstrates value
Testing in Scrum Events¶
Sprint Planning (4-8 hours for 2-week sprint)¶
Tester Involvement: - Review user stories and acceptance criteria - Clarify requirements and ask questions - Identify testability issues - Raise dependencies and risks - Estimate testing effort - Plan test approach for sprint
Testing Activities: - Break down test tasks - Identify test data needs - Plan automation tasks - Allocate test environment - Define testing strategy
Daily Scrum / Stand-up (15 minutes)¶
Tester Updates: - What I tested yesterday - What I plan to test today - Any blockers or impediments - Test environment issues - Defects found
Coordination: - Align with developers on completed features - Flag testing dependencies - Request clarifications - Offer testing support
Sprint Review / Demo (2-4 hours for 2-week sprint)¶
Tester Role: - Demonstrate tested features - Present test results and coverage - Show passing acceptance tests - Discuss quality metrics - Gather stakeholder feedback
Deliverables: - Working software demo - Test summary report - Known issues list - Metrics dashboard
Sprint Retrospective (1.5-3 hours for 2-week sprint)¶
Testing Topics: - What testing practices worked well? - What testing challenges did we face? - How can we improve test coverage? - Are our tests effective? - Tool and environment improvements - Action items for next sprint
Backlog Refinement (Ongoing)¶
Tester Participation: - Review upcoming user stories - Provide testability feedback - Suggest acceptance criteria - Identify test complexity - Raise technical concerns - Estimate testing effort
Testing Throughout the Sprint¶
Sprint Day 1-2: Sprint Start¶
- Participate in sprint planning
- Set up test environment
- Create test plan for sprint
- Prepare test data
- Review and refine test cases
- Begin automation setup
Sprint Day 3-7: Mid-Sprint¶
- Execute test cases as features complete
- Perform exploratory testing
- Log and verify defects
- Collaborate with developers
- Update automated tests
- Conduct API/integration testing
- Daily regression testing
Sprint Day 8-9: Sprint End¶
- Complete remaining test cases
- Execute full regression suite
- Verify all defect fixes
- Validate Definition of Done
- Prepare demo materials
- Update test metrics
- Document known issues
Sprint Day 10: Review and Retro¶
- Demo tested features
- Present quality report
- Participate in retrospective
- Document lessons learned
- Plan improvements
User Story Testing¶
User Story Structure¶
Acceptance Criteria¶
Clear, testable conditions that must be met: - Given [context] - When [action] - Then [outcome]
Definition of Ready (for Testing)¶
- User story is clear and understandable
- Acceptance criteria are defined
- Dependencies identified
- Test data requirements known
- Non-functional requirements specified
- Story is testable
Definition of Done (Testing Perspective)¶
- All acceptance criteria met
- Test cases executed and passed
- Automated tests created/updated
- Exploratory testing completed
- Regression tests passed
- No critical defects open
- Code reviewed
- Documentation updated
Testing Approach by Story Size¶
Small Stories (1-2 points)¶
- Quick manual testing
- Simple automation
- Minimal test cases
- Fast feedback
Medium Stories (3-5 points)¶
- Comprehensive test cases
- Automated and manual testing
- Integration testing
- Multiple scenarios
Large Stories (8+ points)¶
- Should be broken down
- Extensive test coverage
- Multiple test types
- Possibly multiple sprints
Test Automation in Scrum¶
Automation Strategy¶
- Write tests alongside development
- Automate regression tests
- Use Continuous Integration
- Maintain test suite health
- Review and refactor tests
Test Automation Pyramid in Scrum¶
/\
/UI\ 10% - End-to-end tests
/____\
/ \
/ API \ 20% - Integration/API tests
/__________\
/ \
/ Unit \ 70% - Unit tests
/________________\
Sprint Automation Goals¶
- Automate new feature tests
- Maintain existing automation
- Fix broken tests
- Improve test efficiency
- Reduce manual regression effort
Defect Management in Scrum¶
Defect Workflow¶
- Found: Tester identifies issue
- Triaged: Team assesses severity
- In Progress: Developer fixes
- Ready for Test: Fix available
- Verified: Tester confirms fix
- Closed: Issue resolved
When to Fix Defects¶
- Critical/High: Fix in current sprint
- Medium: Next sprint or current if time permits
- Low: Backlog for future sprint
Defect Prevention¶
- Pair programming
- Code reviews
- Definition of Done adherence
- Test-driven development
- Continuous integration
Regression Testing in Scrum¶
When to Run Regression¶
- After each code commit (automated)
- Before sprint review
- After defect fixes
- Before release
Regression Strategy¶
- Automated smoke tests (daily)
- Automated functional tests (every build)
- Full regression suite (before review)
- Manual exploratory (continuously)
Testing Different Types of Work¶
