Debugging the Mind: Teaching Developers to Think Like Testers

For years now, we've been hearing a lot about the tester's mindset. While it remains as important as ever, I believe it has evolved. It has shifted from being the role of one person in the team who explores the application to find edge cases, thinking like a slightly deranged user, to a role that involves teaching this mindset to others. This includes developers, to help them write better unit and integration tests; product owners, to consider the unintended consequences of insufficiently bold ideas; and delivery leads, who may be hesitant to allocate time for proper test setup in the CI/CD pipeline.

I'll discuss how the tester role has evolved based on my experience and what I believe a modern tester needs to keep in mind to inspire their team to prioritise quality in all development activities. These days, critical thinking alone is no longer sufficient. Helping the team to move quickly while embedding quality into our processes has become more crucial than ever.
