QuickCheck is a combinator library originally developed in Haskell that aids software testing through property-based approaches. It automatically generates test cases for test suites while emphasizing the verification of key program properties.

What is QuickCheck?

• Combinator library originally in Haskell

• Assists software testing via property testing

• Automatically generates test cases for suites

• Focuses on verifying program properties

The slide, titled "QuickCheck Philosophy," features a quote from Koen Claessen, co-creator of QuickCheck at the University of Chalmers. In it, he explains how QuickCheck transforms software testing by automatically generating test cases for property-based suites, which promotes comprehensive coverage and detects bugs early.
