By applying early quality measures the Scrum team makes sure to minimize rework. 12

- 16. | Model Based Testing InAgile projects time pressure is felt even more than in tradional IT So creating test cases must be done as easy as possible Let the analysis/design-specialist of the team create “models” (e.g. flowcharts, UML, etc.) Use a Model Based Testing tool to derive test cases. (and sometimes the tester first has to translate a “white-board- model” to a useable format) 16
- 17. | Exploratory Testing Creating testcases in an automated way is great BUT… In order to deal with the challenges of real life Testing also must be a creative activity SO … Exploring is essential. Various ways of Exploratory testing are known, As a minimum: Use charters and logs. And remember Exploratory Testing is NOT Ad Hoc Testing ! 17

Organize support, for example on subjects like: Test Automation (execution, test case creation, …) Non-functional testing (security, performance, …) Test Management (reporting, defect management,…) In larger organizations a central support team can be created, with e.g. the “test manager new style” and the test tooling expert In smaller organizations ad hoc support can be obtained from external entities 19

- 23. | How to dealwith the test strategy? Traditional approach: Based on the Test Strategy, allocate Test Units and Test Techniques In Agile/Scrum: Define the “project test strategy” in the project planning (sprint 0) Define the “sprint test strategy” in the sprint planning. Be aware that the strategy must be adapted to changed circumstances whenever necessary. And, very important: - Regression testing strategy and - Test automation strategy 23 A test unit is a collection of processes, transactions and/or functions that are tested collectively. So this may be anything from a tiny function to a complete business process depending on your goal.

- 25. | Test Strategy: Earlyquality measures “This requirement was not totally correct” is quite disturbing in tradional IT, because unplanned rework has to be done. In Agile IT having the right quality of artifacts is even more important, since the difference between achieving your sprint goals or not is in having adequate quality. So you need early quality measures: • A clear and good Definition of Done • Reviews of intermediate- and end-products • Checklists to help not to forget important things • Standards to help work in an efficient manner 25
- 26. | Regression testing In everysprint the number of products increases. You must make sure products of previous sprints are still OK. Thus regression testing In sprint “n”: • Define test cases for new and changed products • Manually execute these test cases • Keep track of test cases that must be in regression test In sprint “n+1” • Automate the regression test cases • Execute the complete regression test set 26 Programmers usually are very good in programming test tools. At the start of sprint “n+1” they can very wel do a regression test task

- 29. | Test levels areno longer “levels” In the dutch language test levels are called “testsoort” which translates to “test variety” And this exactly says what we still need in Agile: Various scopes of testing The pitfall of Agile teams is to focus on unit testing only. Or to focus on functional testing only. Keep in mind the objectives of all test levels when defining and executing the tests in an Agile team. 29

The sponsors, developers, and users should be able to maintain a constant pace indefinitely. (prevent having a team-burnout; implement the Agile principles in a proper way!)

- 33. | For effective andsustainable testing: Integrate all activities including testing (for as far as possible) Testing is primarily a task for all team members (not necessarily a separate function) Remember to still have your different views on testing (test levels / test varieties) Early quality is more important than ever (do reviews to get it right first time!) 33Rik Marselis, 23 July 2014

Editor's Notes
- #2 Integrate in Agile Process, or maybe better: in Agile teams Webinar Details Presenter: Rik Marselis Time: 2PM (BST) Date: Wednesday 23rd July 2014 In traditional testing a tester spreads the testing activities over various phases. To be able to effectively test in Agile projects the test activities should be properly integrated in the Agile approach. Leo van der Aalst and Rik Marselis published an EuroSTAR eBook on this topic. They start with a vision on Agile testing and, based on that, describe how to effectively integrate test activities in the Scrum approach. In this webinar Rik will go into subjects like "Does the Agile Manifesto have good footholds for testing?", "What is the role of the Product Owner and the Scrum Master", "Which team member(s) perform(s) the testing activities and when?", "How to deal with the test strategy?", "Do we still distinguish test levels" and "how to go about with end-to-end testing?". Very important is the automation of testing activities, not just of the execution but also the specification of test cases. During the webinar Rik demonstrates that the knowledge and expertise of the well-known test methodology TMap is a very solid basis for integrating test activities in Scrum events of an Agile project. Also Rik will mention the link with ISTQB based on the new Agile Extension and the collaboration across the application lifecycle as advocated by DevOps. Key Takeaways: 1) Be adaptive 2) Use a risk-based approach 3) Testing activities must be automated as much as possible

- #13 het gaat om inpasbaarheid van het proces en is daarmee dus een taak van de SM
- #20 Vaak is er wel support over hoe Agile te werken maar niet over hoe Agile te testen.
- #24 Scrum is founded on empirical process control theory, or empiricism. Empiricism asserts that knowledge comes from experience and making decisions based on what is known. laat dit ook voor de teststrategie gelden, dus niet een vast voorgedefinieerd plan maar een plan/strategie dat zich aanpast aan de omstandigheden.
- #27 Automating test cases in Sprint “n” is still an option, find the optimum of not wasting time on double work and not wasting time on automating one-off tests.
