Mike Mannion from Karakun explains why non-deterministic systems, such as large language models (LLMs), are forcing us to rethink the traditional unit test, which assumes a binary outcome in the form of “PASS” or “FAIL.” How can we address this?
The talk has already been very well received in Basel, Bern, and Zurich, and is now coming to Lucerne. 😀

After the talk you can exchange ideas and network with the speaker and professional colleagues over beer and pizza.
