INTRODUCTIONS
• I am…– a tester, team leader, product owner, – a geek ;)
• Bredex is– A software development company– With a strong focus on quality
• Own open source tool• Multi-tool strategy• Agile testing• Scalable test automation

AGENDA
• A short geek-out• A little bit of history• Driving factors for change• Role evolution
– Testers– Developers– Within the team
• Are we ready to be strong? Putting it to the test• Conclusions

IN EVERY GENERATION, A SLAYER IS BORN…
One slayer per generation, and she has the weight of the world on her shoulders…- sound familiar, testers?

CHANGING THE RULES TO WIN THE BATTLE
• Faced with impossible odds, why should only oneperson have the power?
whole team power!
• In agile teams whole team quality!– Weight of testing evenly distributed– Some role and team evolution required– Sadly no magic axe…

DEV-OLUTION STEP 1
Train developers in Exploratory Testing
• Why?– Reduce testing bottleneck– Let tester(s) coordinate and organize
• Who?– About 50% of company developers– And some external people
• How?– Workshop (2 hours)– Cheatsheet– Practice

EXPLORATORY TESTING FOR DEVELOPERS
I don‘t know howor what to test Testing isn‘t my
job / role
I might miss important things

EXPLORATORY TESTING FOR DEVELOPERS
I don‘t know howor what to test
Testing isn‘t myjob / role
• Exploratory Testing is actually a rather naturalprocess• Hands on session before theory
• Cheat sheet to provide test ideas• Practice makes perfect!
• Testers support by defining charters• Whole team• Only DONE is DONE
• We all have blind spots• Developers may find things a tester won‘t• Avoid testing your own things• Discuss possible risks for use as charters

DEV-OLUTION STEP 2
What can we getdone today?
New question in standup meeting:

EVOLVING THE TESTER ROLE

Strategic impulses for our testing- More defined portfolio- Multi-tool strategy
- More technical- Team growth- Training and career paths
Role clarification
More budget for training
Testing community
Automation methodology

TEST STEP 1
• Refining the role
Functional Test Consultant
- Close work with RE/PO- User perspective in testing- Trained in ET and SBTM- Top-Down for automation- Mentoring and Reviews
Technical test consultant
- Close work with developers- Technical aspects of testing- Trained in ET and SBTM- Bottom-Up for automation- Mentoring and Reviews

TEST STEP 2
• Quality of automated (UI) tests– Automated tests are code*– Need to be subject to the same / similar structures as app code– Does this mean that all testers have to code?– Or that only developers should automate?
*even if they are not written in a programming language
![Page 18: SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS … · SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS ... • Exploratory Testing is actually a rather natural ... • Discuss](https://reader034.fdocuments.in/reader034/viewer/2022052608/5ad0253a7f8b9ad24f8d55ce/html5/thumbnails/18.jpg)
TEST STEP 2
• Quality of automated tests– Automated tests are code*– Need to be subject to the same / similar structures as app code– Does this mean that all testers have to code?– Or that only developers should automate?
• It means that the team needs to work together on good automation practices, and that everyone might have something to learn.
*even if they are not written in a programming language

TEAM EVOLUTION
• Quality is important, visible and accessible to everyone
• Automated tests:– Visibility of test results every morning
• Collect results script, analysis and presentation– Classification of regression errors as highest prio– Depending on area of interest, correct analysis level– Everyone can contribute
• Manual testing– Everyone can contribute

ARE YOU READY TO BE STRONG?
![Page 27: SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS … · SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS ... • Exploratory Testing is actually a rather natural ... • Discuss](https://reader034.fdocuments.in/reader034/viewer/2022052608/5ad0253a7f8b9ad24f8d55ce/html5/thumbnails/27.jpg)
ARE YOU READY TO BE STRONG?
• From internal continuous delivery… to releases whenever I want them– No test phases any more– Beta releases after chosen sprints– Official releases when it makes product sense– All involved in testing in sprint– Increased use of git, gerrit and feature branches
• Keep an eye on work in progress• Branch testing not implemented yet
– Whole team quality put to the test• Unknown risk lead to some large problems• Team pulled together for fix – build – test
![Page 28: SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS … · SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS ... • Exploratory Testing is actually a rather natural ... • Discuss](https://reader034.fdocuments.in/reader034/viewer/2022052608/5ad0253a7f8b9ad24f8d55ce/html5/thumbnails/28.jpg)
ARE YOU READY TO BE STRONG?
• Moving to faster releases• Exploratory testing days with developers and
customers– Not everyone likes doing it / does it well
• Testers using tools that require coding (Selenium, …)• Automation patterns being used and further
developed– Interdisciplinary discussions
• Developers using test framework to help automate tests
![Page 29: SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS … · SHARING THE QUALITY RESPONSIBILITY IN AGILE TEAMS ... • Exploratory Testing is actually a rather natural ... • Discuss](https://reader034.fdocuments.in/reader034/viewer/2022052608/5ad0253a7f8b9ad24f8d55ce/html5/thumbnails/29.jpg)
CONCLUSIONS
• The agile development team can contain developersand testers
• The roles don’t have to merge, and not everyone has to be able to do everything
• But there are sensible extensions to each role that can be taught and practised to improve testing and quality
• With training and teamwork, we can realize our potential as team members and within the team
