Team Guide to Software Testability
Team Guide to Software Testability
Better software through greater testability
About the Book
Team Guide to Software Testability is the third guidebook in the new collection from Skelton Thatcher Publications.
A practical guide to how testability can help bring teams together to observe, control and understand the systems they build. Enabling them to better meet customer needs, achieve a transparent level of quality and predictability of delivery.
The ‘Team Guide’ collection is designed to help teams building and running software systems to be as effective as possible.
Guides are curated by experienced practitioners and emphasise the need for collaboration and learning, with the team at the centre.
Manuel Pais is an independent DevOps and Delivery Consultant, focused on teams and flow.
With a diverse experience including development, build management, testing and QA, Manuel has helped large organizations in finance, legal, and manufacturing adopt test automation and continuous delivery, as well as understand DevOps from both technical and human perspectives.
Manuel is co-author of the Team Guide to Software Releasability book and lead editor for the remaining books in the Team Guide series.
