    Send us a text

    On the latest episode of Tech and Test, I’m joined by Elliott Clark, CEO and founder of Batteries Included, for a deep and thoughtful conversation about the cost of testing, what to test (and when), and how to align engineering efforts with your company's mission.

    We cover:

    🧪 What testing is really worth investing in — and where to avoid the trap of "just write more tests"
    ⚖️ Balancing the cost of testing with the speed of product delivery
    🧠 Testing ML systems — and why they require a very different mindset
    📊 Using probabilistic approaches to simulate production traffic data
    📈 Why choosing the right data and metrics is essential to ensuring your engineering team is actually solving the right problems
    🎯 How to make sure your tests, tools, and tracking all support your company’s mission

    A deep dive into the real-world trade-offs of testing at scale — the pain points, the payoffs, and how to make it all work.

    In this episode of Tech and Test, I sit down with Jesús Gianzo Villaverde, a Software Development Engineer in Test, to explore the evolving role of AI in software testing.

    We kick things off by discussing Deepseek, a recent development in the world of AI, before diving into the broader landscape of LLMs and biases—how these models work, where they fall short, and what that means for software testing.

    We share insights into real-world applications of AI and LLMs in software and games testing, including practical use cases, challenges, and the potential use of AI in testing.
