- 2. | PROPERTY OF QVANTEL © 20181 Mr. Kimmo Hakala has M.Sc. (Technology) in Business Information Management with Minor in Hypermedia, Industrial Management and Occupational Safety Engineering from Tampere University of Technology (tut.fi/en). He is working in Finland at Qvantel (qvantel.com), which is a pioneer in the field of BSS and Telco digitalization with over 20 years of experience. Kimmo is a Chairman of Finnish Software Testing Board (fistb.fi) and also member of ISTQB Marketing Working Group (istqb.org). KIMMO HAKALA ABOUT THE SPEAKER
- 3. | PROPERTY OF QVANTEL © 20182 This presentation is based on Kimmo’s experiences in product component QA at Qvantel and it is aimed at everyone willing to know and understand, what are the challenges we’re facing in QA during software product development in BSS & Telco domain and, in the other hand, what are the good practices and success factors, so that we are able to 1. Test the product properly 2. Deliver smoothly and also 3. Continuously improve. The perspective of the presentation is “managerial”. However, we will also discuss about the technical and methodical aspects in component testing like different test levels, methods, test automation, test data management and testing tools. We also take a look at the different expectations towards testing personnel, like documentation, visibility of test activities, re-usable test assets etc. Finally we discuss about the key success factors in QA for software product development.

- 19. | PROPERTY OF QVANTEL © 201819 WHAT IS DATA BROKER? TEST DATA CHALLENGE • IT CREATES DATA WHILE RUNNING TEST AUTOMATION • THIS WOULD ENABLE AUTOMATED TEST SUITE RE-USE IN DIFFERENT ENVIRONMENTS (TEAM SAND BOX, DEVINT,SIT, BSS FULL STACK REFERENCE ETC. ) • INSTEAD OF USING STATIC DATA YOU CALL DATA BROKER TO GENERATE NEEDED DATA AND USE THAT DATA IN AUTOMATION TESTING • THEN YOUR AUTOMATED SUITE IS **INDEPENDENT** OF EXISTING DATA IN TARGET ENVIRONMENT Instead of investigating test data issues I can now use more time in testing

Editor's Notes
- #3: BEFORE QVANTEL I WORKED AT CYBERCOM FINLAND AS SENIOR TEST ENGINEER, TEST MANAGER, QUALITY MANAGER
- #4: THIS IS BASED ON MY OWN EXPERIENCES AND OBSERVATIONS MY MASTER OF THESIS WAS "CHALLENGES TO KNOWLEDGE TRANFER IN SOFTWARE TESTING" MY FAVOURITE TOPICS: BUSINESS INFORMATION MANAGEMENT, KNOWLEDGE MANAGEMENT, INFORMATION SHARING, COMMUNICATION ETC.
- #6: MULTIPLE COMPONENTS, FRONT CHANNEL, DATA MANAGEMENT, DIGITAL BSS CORE COMPLEXITY! SOME DELIVERIES NEED ONLY FEW COMPONENTS
- #7: BUSINESS TO CONSUMER APPS
- #8: We have now 850 + people and in QA 180 people, including release engineers. Co-operation is the key for success! Also our sofware is used by tens of different roles, personas, B2B, B2C and qvantelees HAVE YOU EVER THINK ABOUT HOW MANY DIFFERENT USER TYPES WE HAVE? HAVE YOU EVER THINK ABOUT HOW MANY DIFFERENT USERS HAVE A IMPACT TO SOFTWARE UNDER DEVELOPMENT?
- #9: WE NEED TO INVOLVE TESTERS EARLY!
- #10: GROWTH OF THE COMPANY! COMPETITIVE IMPROMENT SOLUTIONS, RE-INVENTING THE WHEEL
- #11: HUGE AMOUNT OF SKILLS!
- #12: WE CAN’T FIND WHAT WE’RE LOOKING FOR BUT THAT’S FINE!
- #13: IT’S IMPORTANT TO BUILD GOOD COMBINATION OF DIFFERENT PEOPLE
- #14: TEST LEVELS ARE STILL VALID! THE EARLY BIRD CATCHES THE WORM UNIT TESTING VS. COMPONENT TESTING UNIT TESTS ARE IMPORTANT IT'S ABOUT QUALITY ATTITUDE OF DEVELOPERS!
- #15: WE NEED TO FULFIL THE NEEDS OF DIFFERENT CUSTOMER DELIVERIES
- #16: HOW WE CAN DO THAT?
- #17: LET'S CONTINUE WITH THE TOPIC RE-USABLE TEST ASSETS, AUTOMATION
- #18: THESE ARE GOOD PRINCIPLES BUT NOT ENOUGH!
- #19: CUSTOMER 1 & 2 EXISTS AND ARE KNOWN
- #21: Data Broker is a supporting service in Qvantel's BSS stack. It provides data content generation, creation and manipulation functionalities by using standard BSS APIs and services. The primary use case is to generate and populate live BSS systems with data for quality assurance and testing purposes.

- #29: TRUST ENABLES COMMUNICATION AND COMMUNICATION ENABLES COLLABORATION -Is your component checked by some static code analysis tool (staticCodeCheck build step)? -Are the CI tests set up in the recommended way (unit/integration test and test coverage reporting)? -Are the component tests enabled for your component and are the executions automated in the Jenkins pipeline?
