What if Da Vinci had been a software tester? - Barış Sarıalioğlu

In this episode, I talk with Barış Sarıalioğlu about testing as art and science, through the lens of Leonardo da Vinci. We ask what a tester can learn from curiosity, observation, and experiments. Mona Lisa's smile shows how uncertainty beats 100 pages of metrics. We should aim for understanding, not bug counts. We talk about storytelling, simple reports that people can read, and mixing engineering with empathy. Testers work across disciplines, explore, and make sense of messy projects. Perfection is a trap. Good enough can be great. Balance logic and imagination, and you get impact that reaches beyond tools.

Highlights:

• Testing requires both analytical precision and creative imagination: the logical side handles data and observation, while the creative side supplies empathy, intuition, and holistic thinking.
• A test report's value is determined by how well non-technical stakeholders understand it, not by how many metrics or pages it contains.
• Simplicity in testing is not the default outcome; it must be set as a deliberate target, because left unmanaged, testing projects grow complex on their own.
• Testing is best defined as building valuable understanding of a product's quality, not as breaking software or delivering bad news to developers.
• Imperfection in software is permanent and structural: chasing a bug-free or optimal product is a false goal, and accepting this frees teams to focus on real-world user impact.
