Slide 7 - Pros and Cons

The slide outlines the pros of the tool, highlighting how it automates test generation to save time, efficiently detects missed edge cases, and integrates seamlessly with Haskell for better workflows. On the cons side, it notes the upfront effort needed to define properties and a potential learning curve for beginners.

Pros and Cons

ProsCons
Automates test generation to save time and effort. Efficiently uncovers edge cases that manual testing might miss. Seamlessly integrates with Haskell for enhanced development workflows.Requires upfront definition of properties, which can be initial overhead. Presents a learning curve that may challenge beginners new to the tool.
