What are the best practices in property-based testing?

Property-based testing focuses on defining properties that your code should satisfy. Best practices include defining clear properties, using shrinking to minimize failing cases, and integrating with existing test suites.

Can you explain what shrinking means in this context?

Shrinking is the process of reducing a failing test case to the smallest possible input that still causes the failure. This helps in diagnosing issues more effectively.

How do I choose properties to test?

Choose properties that are fundamental to the behavior of your code. They should be general enough to cover a wide range of inputs but specific enough to catch edge cases.

Are there any tools you recommend for property-based testing?

Yes, some popular tools include QuickCheck for Haskell, Hypothesis for Python, and ScalaCheck for Scala. These tools help automate property-based testing.
