- 3. @janetgregoryca How the whole team working together improves product quality … and that testing activities belong to the whole team 3
- 6. -- testing activities “Accelerate the achievement of shippable quality” -- a tester’s job Brent Jensen, 2011 6 Good testing …. • provides information about the product through fast feedback loops • is more than testing software • is about learning about the product and what it can and can not do
- 8. @janetgregoryca Excerpt from Agile Testing pg. 46 Several people we've talked to described the 'mini-waterfall' phenomenon that often occurs when a traditional software development organization implements an agile development process. The organization replaces a six-month or year-long development cycle with a two- or four-week one, and just tries to squeeze all of the traditional SDLC phases into that short period." 8
- 9. @janetgregoryca • an activity; not a phase (Elisabeth Hendrickson) • interactive and starts from the beginning • more than testing code 9 Potentially shippable product Potentially shippable product
- 10. @janetgregoryca 10 • Think about the primary roles / specialties on your current team? • Are there specialties outside your team that help …or hinder your team to achieve your quality goals? • Are there dependencies on others? Share in the chat. Example: and ops specialist to help with a test environment issue.
- 12. @janetgregoryca • Who actually does what? • Can everyone do everything? …. and do it well? 12
- 13. @janetgregoryca • Developers think about testability • Testers think about the big picture and what ifs… • Multiple skill sets mean better solutions 13
- 14. @janetgregoryca What makes it work? • Commitment to a level of quality ➢ Identifying what’s valuable to customers ➢ Bug prevention over bug detection ➢ Fast response to prod issues • Diverse perspectives, skill sets, biases • Competencies > roles

- 17. What are some of the testing practices and activities that can be shared? Take a minute and share in the chat
- 18. @janetgregoryca Feature (with examples) User Story High- Level AT Fix Defects Code, test & automate story ATDD Acceptance Test Driven Development Accept Story Explore Examples
- 19. @janetgregoryca Expand the tests Pair to discuss automation Create test method(s) Write the tests in the automation framework Select a test and run it Repeat until all tests have passed Perform exploratory testing, and any other testing required for the definition of DONE. Acceptance Test(s) TDD
- 20. @janetgregoryca • Examples provide common language • Shared common understanding • Coding and testing concurrently • Shared definition of DONE • Prevents defects in code 20
- 21. @janetgregoryca It’s not just about code !!! ◦ Test assumptions ◦ Uncover hidden assumptions The goal: ◦ Shared common understanding of the story ◦ Preventing defects (eliminate waste)
- 24. @janetgregoryca • Checking: Does the system do what it's supposed to do? • Exploring: Are there any other risks or vulnerabilities that we haven't thought about yet? • Testing == checking + exploring 24 **Elisabeth Hendrickson, “The Two Sides of Software Testing”, Agile Connection GUI API Unit Tests

- 31. @janetgregoryca Instead of ◦ We’re here to find bugs … or ensure requirements are met … or break the software … Think –What can I do to help deliver the product successfully! 31
- 32. @janetgregoryca Instead of We’re here to code and throw it over the wall and then fix bugs Think What can I do to help create testable code and deliver the product successfully! 32
- 33. @janetgregoryca Instead of We’re here to tell you what we want, and you just do it. Think How can I work with the development team to deliver the product successfully? 33
- 34. @janetgregoryca Testers are NOT responsible for quality, the whole team is Programmers do not code alone ….. everyone helps them understand what to code
- 36. @janetgregoryca Building a quality culture • Transformative leaders • Trust and psychological safety • Focus on quality, not speed Teams and organizations talk about what level of quality they desire, and everyone knows how they contribute to the quality of the product.
