This document summarizes a presentation about shifting testing practices to support continuous delivery. It discusses myths around continuous delivery, benefits of CD, and how the speaker transformed their organization PaddyPower into a high performing CD organization. The speaker discusses shifting testing activities left to involve testing earlier in development, improving collaboration activities, and shifting testing activities right to involve monitoring customer usage and feedback. Communication skills like active listening, empathy, and influencing were important for testers to collaborate effectively in this new approach.

talk on this?

5. What is CD?
“Continuous delivery (CD) is a
software engineering approach in
which teams produce software in
short cycles, ensuring that the
software can be reliably released at
any time. It aims at building, testing,
and releasing software faster and
more frequently.” - Wikipedia

Reduce complexity
BDD

Pair programming
Code reviews
Mob programming

Improve testability
Reduce multitasking through WIP
Design for resilience
Design for availability
Design for performance

25. Improve the centre
activities
