Tester's Digest

A weekly source of software testing news


ISSUE #47 - February 11, 2018

You can’t test the quality in, they say. So how do we get to build software at a better quality level?

How to build Web APIs for success, principles from Salesforce, including “Trust in Acceptance Tests” (BDD style) and “Log, Monitor and Alert” – I couldn’t agree more.


Nice little rant imploring developers to deliver software that’s challenging for testers to find bugs in:

While this paper outlines costs (15% increase in development time) and benefits: “improves design quality, reduces defects, reduces staffing risk, enhances technical skills, improves team communications and is considered more enjoyable”


Tester-developer pairing technique promises benefits in learning on both sides, earlier bug discovery, and more maintainable automated tests:


Mobbing technique with both programmers and testers participating can “turn programmers into better testers, and improve any testers capabilities”.



Worth learning: On more effective ways of presenting test information to others, based on data visualization principles from Edward Tufte, the god of viz:
