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

As a [user type]
I want [goal]
So that [benefit]

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

  1. Found: Tester identifies issue
  2. Triaged: Team assesses severity
  3. In Progress: Developer fixes
  4. Ready for Test: Fix available
  5. Verified: Tester confirms fix
  6. 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

Feature Development

  • Full test cycle
  • Acceptance criteria validation
  • Automation development
  • Exploratory testing

Bug Fixes

  • Verify fix works
  • Regression testing
  • Root cause understanding
  • Update related tests

Technical Debt

  • Testing improvements
  • Refactoring verification
  • Updated test coverage
  • Performance validation

Spikes (Research)

  • Proof of concept testing
  • Feasibility assessment
  • Risk evaluation
  • Learning and exploration

Metrics and Reporting in Scrum

Sprint Metrics

  • Velocity: Story points completed
  • Burndown Chart: Work remaining over time
  • Defect Trend: Found, fixed, open defects
  • Test Coverage: % of stories tested
  • Automation Coverage: % of automated tests
  • Build Stability: Pass/fail rate

Quality Metrics

  • Defects per story
  • Escaped defects
  • Test case pass rate
  • Automation ROI
  • Test execution time
