Requirements + Design Implementation Testing Maintenance
Waterfall process
Agile Testing doesn’t work
When testing becomes
a separate activity
Todo Development Testing Done
Task 15 Task 13 Task 14
Task 5 Task 6 Task 7 Task 8 Task 9 Task 10 Task 11 Task 12
Task 1 Task 2 Task 3 Task 4
Scrum fall
Agile Testing doesn’t work
When team determines
tests during sprints
Becoming predicable?
Sprint X
Development Team
Unit Testing
Integration Testing
Automation Team
Acceptance Testing
Don’t split development & testing
Whole Team Approach
Specification Workshop
Sprint planning Implementation
Sprint
Review
Testing / Knowing upfront
Specification By Example Workshop
Individuals & Interaction are more important than
Processes & Tools
Why a Specification Workshop? Shared understanding of domain
Assumptions

“Son, please go to the market and buy 1 bottle of milk. If they have eggs, bring 6 ”
What did he bring home?
Create a common understanding Using Real Examples

Agile Testing doesn’t work
When testers & developers
don’t really collaborate
Lets be honest… Some developers get TEST lazy
Testing
Not about breaking But preventing
The Dark Side
Why testers & developers should work together
Developers are great automaters!
Agile Testing doesn’t work
When testing is about zero bugs
Bad Quality?
Bad Quality?
Zero Bugs does not mean you’ve measured quality
Wait and see how it performs in the real world
It’s not low quality because it has 5 bugs
It’s low quality because people aren’t coming
~ Gojko Adzic
Low quality
Agile Testing doesn’t work
When it’s all about bugs status reports
Fire drill effect
Stop tracking stupid things nobody cares about
Are these measurements important to business?

Stop maintaining low level risk tests
Drive your testing effort
Agile Testing doesn’t work
When you focus on automation tools
UI
Integration
Unit
Acceptance tests too costly to maintain Avoid big tests in sequence and checks at the end
The Next Move
Drop the Testing Column – Test always
Specification by Example – Shared Understanding
Testers and Developers pulling the same direction
Measure what is important for the business
Shared agreement with business
Don’t focus on tools
Agile Testing will work when …
Coming together is a beginning. Keeping together is progress. Working together is success.
