QA Activities
Required
Regression testing
Iteration/release tasks testing
Optional
Release/demo management
Documentation management

Regression Testing
Goals
Verify existing functionality
Check new integration points
Show and monitor project status
Check existing documentation

Regression Testing
Issues
Functionality is growing too quickly
Not enough QA engineers
Too much manual work
Setup and configuration issues
Testing without plan/structure

Iteration/Release Tasks Testing
Goals
Check new functionality
Show iteration/release status
Update/create documentation

Iteration/Release Tasks Testing
Issues
Too many bugs in implemented tasks
Not enough time to the end of iteration
Regression testing is not finished
Tasks are too large
Long feedback/bug-fixing loop
QA work is not included in ‘DONE’ criteria
Switching of environments

Release/Demo Management
Issues
Full regression is not finished
Bug fixes produces new bugs
Release/demo is prepared in the next iteration

Documentation Management
Issues
No documentation at all
Documentation is hard to maintain
Too much time is spend for documentation
Documentation is not up to date
Documentation is not shared

Common Issues
QA team is not collocated with developers
QA team members are part-time
Developers defend their code from QA
QA team don’t share project interests
QA tools minimize face-to-face interaction
Lack of respect for QA work
QA team is not enough skilled

QA Iteration 1 2 4 3 6 5 8 9 7 10 days Phase I: Planning Phase II: Acceptance Testing Phase III: Stories Testing Phase IV: Regression Testing Phase V: Demo

Phase I: Planning
Goals
Complete understanding of sprint scope
Prioritization of tasks in the sprint
Additional point of view on stories
Increasing team collaboration
Best practices
Full QA team take part in planning
QA team members estimate stories
Some time at the end of iteration is reserved
QA estimations are used to order tasks
Both manual and automated tests are estimated

Phase II: Acceptance Testing
Goals
Document new functionality
Prepare tests for ATDD
Decrease time for regression testing
Automate ‘DONE’ criteria
Best practices
Don’t use too technical tools
QA writes test, developer writes fixture
Test stories at the top of sprint backlog
Organize tests as documentation
Developers help QA to prepare tests
Completely automated testing environment

Phase III: Stories Testing
Goals
Complete ‘DONE’ criteria
Integrate and check new functionality
Early preparation to the demo
Best practices
Use branches for large tasks or demo branch
Reduce amount of manual testing
Start story testing as soon as possible
Update test suite for bugs and issues
Completely automated testing environment
Developers often integrate code on local machines

Phase IV: Regression Testing
Goals
Check integration of all implemented stories
Preparation to the demo
Prepare sprint status
Best practices
Division of automated tests in suites
Easy and short stories at the end of sprint
Buffer for team internal tasks
Developers help to perform testing
Some kind of code freezing
Categorization of bugs and issues
Update project testing metrics

Phase V: Demo
Goals
Demonstrate implemented functionality
External demo
Share project knowledge and experience
Best practices
Prepare to the demo during sprint
Include demo preparation in ‘DONE’ criteria
Automated environment for demo
All team members present at the demo
Demo is driven by QA team member
Fixed time and place for sprint demo

Phase VI: Retrospective
Goals
Share knowledge about QA process
Analyze and improve QA process
Increase integration with developers team
Analyze team structure
Best practices
Use external facilitator
Members of other teams present
Gather and share project metrics
Use experience of developers team in retrospectives

Best Practices
Use engineer practices
Unit testing
TDD
ATDD
Continuous integration
Code review
Pair programming
Static analysis

Best Practices
QA team is collocated with developers
Product owner works with QA for AT
At least 1 QA for each 2 developers
Increase QA team incrementally
Developers help with all technical stuff
Use short internal iteration before release
Calculate and publish testing metrics
Provide traceability for tests
