How can I implement property-based testing in my project?

Property-based testing involves defining properties that your code should satisfy and then generating random inputs to test those properties. You can use libraries like QuickCheck for Haskell or Hypothesis for Python.

What are some common properties I should test for?

Common properties include idempotence, commutativity, and associativity, depending on the functions you're testing. For example, if you're testing a sorting function, you might check that the output is always sorted.

Can you give me an example of a property-based test?

Sure! For a function that adds two numbers, you could test the property that adding zero to any number returns the number itself. You would generate random numbers and check this property.

What are the benefits of using property-based testing?

Property-based testing can uncover edge cases that traditional example-based tests might miss, leading to more robust code.
