How testing is often perceived

Two IT people are cycling up a hill on a tandem-bike. When they finally reach the summit the one in front, the developer, says: ‘It was hard but we made it!’ Then the one at the back, the tester, comments: ‘Yes and I hope you appreciate that I was using the brakes all the time because otherwise we would have rolled down the hill backwards’ Use TMap HD to make sure you are a tester that helps cycling up the hill !!

Element People: the T-shaped professional The difference between failure and success is in… the People involved  Human Driven as opposed to Process Driven  Skills, Knowledge and Experience of the individual are crucial  Team responsibility vs.  Personal responsibility Working with the TMap Suite | 15

The modern tester … must be:

… needs to possess:

 Curious

 People-skills

 Creative

 Testing-skills

 Quality driven

 Tooling-skills

 Willing to learn

 Observational skills

 Multi-disciplinary

 Domain knowledge

Element: Integrate Collaboration across the entire Application LifeCycle • Reviews and clear handovers in traditional lifecycle • Integrated cross-functional teams in iterative lifecycles


Element: Simplify IT is rapidly becoming more complex and more difficult to manage. To reverse this trend we must simplify. By using standard components the process and product become simpler. As a tester we can use test design techniques to make sure we have just enough test cases. Don’t do unnecessary activities. Work in short cycles with clear goals. Working with the TMap Suite | 18

Element: Industrialize  Automate and Standardize  The tester needs to develop an additional skill set  Recognize opportunities, even if you can’t realize them yourself


Element: Industrialize Industrialize is about being efficient and effective Automated test design Automated test execution Automated test data management Automated test environment management But also: Checklists Comparators Tools to specify expected outcomes Etc. Working with the TMap Suite | 20

10-9-2015

Testing needs different angles and views  Today people are hesitant to use the word ‘Test Level’ since it seems to imply hierarchy.  Testers often struggle to distinguish between Test Levels and Test Types.  What should the focus of testing should be?  What stakeholders should be involved in testing? Do they have different needs?  Inexperienced Agile teams often do unit testing only, they forget the need to look from other perspectives

Test approaches

•

What do these terms mean?

•

What is the difference?


Test approaches with TMap HD Experience based

Coverage based

1.

Checklist Used for static & dynamic testing

1.

Process e.g. Proces Cycle Test

2.

Error guessing Based on previously encountered defects

2.

Conditions e.g. Elementary Comparison Test of Decision table

3.

Exploratory testing Learn, design and execute in parallel

3.

Data e.g. Data Combination Test

4.

Appearance e.g. Syntactic or using user profile Working with the TMap Suite | 43

Coverage based testing + Industrialize = COVER Confidence through built-in Quality


COVER: de testontwerptool van Sogeti Ontwerpen van: • testsituaties, • testgevallen en • fysieke testgevallen Diverse technieken Working with the TMap Suite | 51

Uitleg workshop In teams van + 4 mensen: Ontwerp testgevallen, m.b.v. COVER met PCT en DCT Noteer de testgevallen op de logsheet Voer de testgevallen uit Rapporteer je resultaten Als je klaar bent: vraag om de exploratory testing charter Working with the TMap Suite | 56

Workshop; De OV-korting-case



23

10-9-2015

Toelichting PCT PCT: - Teken de procesflow met www.draw.io - Exporteer de flow als XML (plain) - Importeer de XML in COVER - Genereer de logische testgevallen - Maak op een logsheet de fysieke testgevallen - Voer de fysieke testgevallen uit


Toelichting DCT DCT: - Bepaal de verschillende gegevens - Bepaal per gegeven de equivalentieklassen - Ga naar “data” in COVER, en kies “genereer testgevallen” - Vul de gegevens in en de verschillende klassen - Genereer de testgevallen - Maak op een logsheet de fysieke testgevallen - Voer de fysieke testgevallen uit



24

Terugkoppeling Hoeveel testgevallen heb je gemaakt? Wat zijn je testresultaten (passed/failed/observations) Heb je bevindingen? Met welk testgeval heb je de bevinding gevonden?


Terugkoppeling en conclusie Coverage based testen met tooling zodat je op een efficiënte manier een aantoonbare dekking hebt

Experience based testen om aanvullende dekking, en vooral vertrouwen te krijgen Combinatie van gegenereerde dekking en hersenkracht geeft optimaal testen.
