The Illusion of the Typical Tester and What We Miss - Isabel Evans

In this episode, I talk with Isabel Evans about breaking stereotypes in the IT and testing industries. We go into the common misconceptions about testers, like the idea that they are mostly quiet, socially awkward individuals. Isabel shares her research findings, revealing that testers come from a wide array of backgrounds, including acting and arts. We discuss how this diversity enriches the field and challenges current hiring practices. The conversation opens up new perspectives on creating more inclusive environments in tech, prompting us to rethink who we see as a good fit for these roles.

"Only six percent of testers met that IT stereotype." - Isabel Evans

After over 30 years in industry, software quality and testing practitioner Isabel Evans is now a PhD student at the University of Malta. Her research takes a human-centered approach to the development of testing tools. This arose from real experiences in industry and led to the academic papers: 'Stuck in Limbo with Magical Solutions', 'Scared, Frustrated and Quietly Proud', and 'Test tools: An illusion of usability'. Research continues with modeling and testing a framework of heuristics to help teams develop and evaluate testing tools. Isabel is the author of the book "Achieving Software Quality Through Teamwork" and has chaired EuroSTAR (2019) and HUSTEF (2018). Her tutorials and storytelling keynotes are very popular at conferences worldwide. She is a Fellow of the British Computer Society and was awarded the EuroSTAR Testing Excellence Award in 2017.

Highlights:

• Only 6% of testers in Isabel Evans's survey sample matched the IT stereotype from recruitment databases, meaning the overwhelming majority of practicing testers do not fit the narrow profile those databases promote.
• Recruitment and careers advice databases actively narrow the field by directing only stereotypically "nerdy, non-social, arts-averse" candidates toward IT, which filters out the diverse people who already make up the profession.
• Arts graduates in the survey sample were doing test automation and technical testing roles at a rate of around 40%, and IT graduates were equally likely to be in non-technical roles, so degree subject does not predict role or aptitude.
• The biggest quality problem testers reported with their tools was not aesthetics but operability: tools with attractive interfaces often failed to support actual testing workflows, creating what Isabel Evans calls the illusion of usability.
• Isabel Evans distilled her research findings into 12 heuristics, framed as open questions, designed to help tool designers and evaluators think through who a tool is for and how it supports real testing work.
