`proptest`
Test Data Generation with `fake`

Property-based testing involves defining properties that your code should satisfy for a wide range of input values. You describe the general behavior of the program, and the testing framework generates random inputs to check if the properties hold true. Example:

Suppose you have a sorting function. A property you could test is that the output list should have the same length as the input list, and the elements should be in an increasing order.

Consider using:

proptest⮳: A powerful crate for property-based testing, where you define properties that your code should satisfy, and proptest generates many random inputs to verify those properties.
quickcheck: Another property-based testing crate. proptest is often preferred for its flexibility.
