Testing in a Continuous Delivery World

On February 08, 2017, I went to the Continuous Delivery Meetup in Amsterdam. There was a talk on ‘Testing in a Continuous Delivery World’ by Wouter Lagerweij

  • Goal statements tell us if this initiative is aligned with the vision of the organisation.

Knowing the expectations for each of these aspects is crucial to understanding the problem at hand, and then breaking it down into smaller problems that guide us towards the big vision.
