Property-based testing becomes easier with Hedgehog

Hedgehog is a brand new property-based testing system.

In mainstream scenarios it

• makes properties less fragmented
• doesn’t require to write shrinkers; it does it for free
• provides fine-grained control over the scope and shrinking of generated values

It is available for

• Haskell
• F#
• R
• Scala

Jacob Stanley, the creator of Hedgehog, made yesterday an announcement on Haskell Reddit and overall received interesting feedback, including one from Koen Claessen¹.
