Discover QuickCheck: Haskell Library for Automated Property-Based Testing

Source: Based on Wikipedia

QuickCheck is a combinator library for the Haskell programming language that supports property-based testing by automatically generating test cases using random inputs to verify software correctness. It prioritizes defining and checking general properties rather than relying on specific examples.

What is QuickCheck?

• Combinator library for Haskell programming
• Generates test cases for property-based testing
• Ensures software correctness via random inputs
• Emphasizes properties over specific examples
