Browser Testing Using Grammars and a Consensus Oracle

Explore property-based testing for browser rendering in this 43-minute conference talk from Strange Loop. Learn how to generate interesting web page inputs using controllable grammar-based generators and create a test Oracle to detect incorrectly rendered pages. Discover the benefits of using multiple rendering engines to identify failing test cases through lack of consensus. Understand how property-based testing shrinks failing cases to their bare minimum, aiding in root-cause analysis. While focusing on browser render testing, gain insights into applying this technique to other software systems with preexisting implementations. Presented by Joel Martin, this talk offers valuable strategies for improving web browser testing methodologies.
