Developers time on testing is closer to 1 hour a day

Test automation plateaus too, and manual testing
resists to go away

As Continuous Delivery Matures Performance Testing
Is The Next Blocker
Performance done at the end is complex
and costly
Centralized performance testing isn’t scalable
Completely disrupts continuous delivery

How can we address
these challenges?

Modernize Testing With Continuous Testing

Sprint definition of "done" includes
your sprint testing goals (Done
done, test data strategy,
automation, cntrl. Gates…)
Define Test Scenarios using a
DSL (e.g: Gherkin)
Include Performance Testing in
Acceptance Criteria
Feature toggles, AB Multivariate…
Prioritize bugs on backlog

Make Sure Its Clear Who Needs To Test What….
