In a company that was used to test the features in a more manual way, the continuous growth and the evolution to continuous delivery makes that the test mindset had to change. The way we were used to perform testing changed to adapt to the new needs of Continuous Delivery, where we need to be fast to validate the increasing number of builds while not losing confidence on the quality of the delivery.
We adopt the "shift left" strategy to testing and increase automation to fit to the CD strategy with a series of pipeline stages where we exercice different parts of the software increasingly so that when we reach the end we have very few validations to be made manually.
Starting to think on which types tests I should use for one given User Story and in wich levels of the pipeline should I use them introduce a challenge for our testers that were not used to think on testing this way.
So if you want to know the kind of gear you need to climb the testing pyramid in a CD environment keep in touch :)
