We’ve all heard this story before. “Testers need to be more technical”. The problem with that statement is that too many people read that as, “Testers need to code”. While learning to code or learning to automate can be helpful for a testers growth, there are many, many other (and often, more effective) ways to “be technical” – and valuable, as a tester without writing code.
In this session, long-time test specialist Alan Page rants a bit about the subject, and then shares several real examples of practical tools, techniques, and approaches that will help anyone become a more “technical” tester.
