Working with legacy code is hard, especially when you lack the safety net of tests. But what if you could add tests with a single click?

I’ve spent my career wrestling with legacy systems, and I’ve learned that the biggest hurdles aren't logical — they're mechanical. Breaking dependencies and setting up test doubles are tedious, manual tasks that drain valuable time and energy.

Whenever I find myself doing repetitive work by hand, alarm bells go off. Why aren’t we automating this?

That question led me to build SpecRec: a system that automatically injects dependencies and records real interactions to generate golden master tests. It’s not about AI-generated tests—it’s about a deterministic, provably correct approach to testing.

By automating the most painful parts of testing legacy code, SpecRec helps you ship with confidence, reduce technical debt, and finally breathe easy.

In this talk I'll show you how SpecRec works, and you'll leave knowing how to automate testing of even the most challenging legacy codebases, freeing up your time to focus on innovation.
