Learn to be a storyteller because unless you are a candidate for a reality show, no one else is going to tell your story for you. So tell us a story. Tell us a good story. And let that good story be one part of a symphony of stories that makes this world a better place.” James Whittaker © Dragons Out Oy 8 https://medium.com/@docjamesw/the-storytelling-manifesto-f17548a358b3
- 9. Why testing for children? • Coding has started to interest children and youth. • Many parties in our societies promote coding e.g. via coding schools • There is not enough software testing education • Testing is even over half of all software development work • There is also a lack of testers, not only a lack of coders • Testing is the new basic skill • Good quality is needed in software development in Finland and around the world • We need to make software testing familiar already to children • Testing schools • Testing books • My own solution, on top of all the coding schools, is to offer children a book about software testing © Dragons Out Oy 9

- 13. Power of the story Story • Swanlake turned her horse around and rode fast back to the palisade. She called to the knights and building master Aidan that the dragon was coming. All the sharpened trunks needed to be moved urgently to the hole in the palisade. Spears and swords, whoever had them, should be fetched immediately. All available water should be poured into buckets. Then she went to find Yellowbeard at the castle. Explanation • In the story the dragon arrives to a village in the middle of the repairs of the palisade. Similarly, most of the defects are found in software during software development, before the software is released. Then the people who look for defects (testers) and fix defects (coders), are always available. Usually a tester finds the defect, so doesn’t wait for a user to find the defect later. In this story Swanlake was a tester who found and identified the defect, that is the dragon. As a tester she couldn’t this time fix the defect but needed coders (developers) to help. © Dragons Out Oy 13

- 15. Annoying dragon • Defect name: Memory leak • Severity: Medium • Defect symptoms: The computer gets slower, until it can’t function at all, and it shuts down • Cause of the defect: Memory is reserved for use of the software, but it is not freed after usage • Root causes: Developer is not careful in freeing the memory. May not know how, may not remember. • Testing: You measure used memory as you use the software. If the amount of used memory increases all the time, it is probably a memory leak. • Fix: You run the software one line of code at a time, until you find the spot that should be fixed. Memory is released with a proper piece of code. © Dragons Out Oy 15
- 16. Robbing dragons © Dragons Out Oy 16 • Color: Glittering green, or gray • Size: Small to large • How difficult to find?: Easy to difficult • How difficult to get rid of?: Easy to difficult • Flies?: Some fly, some don’t • Wings: Small to large • Breaths fire?: Yes • Favorite thing: Stealing food and treasure
- 17. Robbing dragons • Defect name: Functionality defects • Severity: Low-Medium-High • Defect symptoms: The software doesn’t do what it should do. Calculation gives wrong result. User sees information in the wrong place. • Cause of the defect: The functionality has been coded wrong. • Root causes: Developer has not understood, what the user has meant. Or the defect exists due to carelessness, or hurry. • Testing: You use the software normally, based on tester experience or requirement definitions. • Fix: Code is changed to work correctly. © Dragons Out Oy 17
- 18. Mean dragon • Color: Black • Size: Small • How difficult to find?: Difficult • How difficult to get rid of?: Medium • Flies?: Yes • Wings: Medium • Breaths fire?: A lot • Favorite thing: Stealing food and treasure without being detected © Dragons Out Oy 18
- 19. Mean dragon • Defect name: Security defect • Severity: High • Defect symptoms: Information from the software is found outside the system (e.g. bank card information). It could also be just software functioning wrong. • Cause of the defect: A criminal has used security defect to break into the system, and then has stolen or destroyed something. • Root causes: Developer has not followed the latest secure coding principles. Maybe doesn’t know these. • Testing: You look for known vulnerabilities in the software by using it, or via a security testing software. You can also review code. Checklist of known defects helps. • Fix: A known vulnerability has also a known fix. It is fixed in the code or system settings. © Dragons Out Oy 19
- 20. Underground dragon • Color: Brown • Size: Large • How difficult to find?: Easy • How difficult to get rid of?: Medium • Flies?: No • Wings: Small • Breaths fire?: A lot • Favorite thing: Finding easy food and eating © Dragons Out Oy 20
- 21. Underground dragon • Defect name: Hardware defect • Severity: High • Defect symptoms: Some part of or all of the computer doesn’t work. • Cause of the defect: A part of hardware has broken over time. • Root causes: A part of hardware may be of low quality, so it doesn’t last as long as it should. Possibly the part doesn’t work well with other parts, so it breaks. • Testing: You use the system normally. You observe the hardware. Test environment uses similar hardware than the users will have. • Fix: You change a broken part to a new one or change to a part that better fits other parts. © Dragons Out Oy 21
- 22. Nice dragon • Color: Glittering green • Size: Medium • How difficult to find?: Easy • How difficult to get rid of?: Easy • Flies?: Yes • Wings: Medium • Breaths fire?: Yes • Favorite thing: Eating animals and helping people © Dragons Out Oy 22
- 23. Nice dragon • Defect name: Defect seeding, mutation testing - a defect created on purpose • Severity: Low • Defect symptoms: It looks like the functionality works wrong, e.g. wrong result from a calculation. So, the defect looks like a functionality defect. • Cause of the defect: Tester or coder has created the defect into the code on purpose. • Root causes: The idea is that when all seeded defects have been found, all defects have been found. • Testing: You use the system normally and try to find all seeded defects. You will also find real defects. When the last seeded defect is found, you can stop testing. • Fix: Remember to fix the code also for the seeded defects, in the same way as for real functionality defects. © Dragons Out Oy 23

- 45. How children learn? • Stories, examples • Identifying with others, Idols • Imitating • Rhymes, songs • Playing, games • Exploring, doing, trial and error • Simplicity, clarity • Repeating • Remembering • Boundaries (right and wrong) © Dragons Out Oy 45
- 46. Many learning strategies is a good thing • “Children and teenagers learn by observing, listening, exploring, experimenting and asking questions” (1) • “The broader the range of strategies that children can use appropriately, the more successful they can be in problem solving, in reading, in text comprehension and in memorizing. “ (2) © Dragons Out Oy 46 1 https://raisingchildren.net.au/school-age/school-learning/learning-ideas/learning-school-years 2 http://www.ibe.unesco.org/sites/default/files/resources/edu-practices_07_eng.pdf
- 47. Storytelling works for all learning styles • Visual learners like the mental pictures they get from storytelling • Auditory learners connect with the words and the storyteller’s voice. • Kinesthetic learners can hook into the emotional connections and feelings from the story. • Storytelling also helps with learning because stories are easy to remember © Dragons Out Oy https://www.harvardbusiness.org/what-makes-storytelling-so-effective-for-learning
- 48. Focus on 10-12 year olds or “Tweens” • “Around the age of 11 or 12, children learn to think about abstract concepts.” • “Tweens display strong metacognition skills, i.e. ability to think about thinking. Children display this ability through an awareness of knowledge, an awareness of thinking, and an awareness of thinking strategies.” • Software testing is essentially about thinking what we already know and expanding that knowledge by exploring. © Dragons Out Oy 48 https://www.scholastic.com/parents/family-life/creativity-and-critical- thinking/development-milestones/cognitive-development-11-13-year-olds.html
