The Role of AI in Testing with Debbie O'Brien
How has testing changed in the era of AI? Carl and Richard talk to Debbie O'Brien in her new role at Zephyr about using LLMs to help build and validate tests - and much more. Debbie talks about joining Zephyr and using testing tools like Playwright to validate application workflows and generate documentation.
