mock-property is a utility library that allows developers to temporarily replace or delete a property descriptor on an object, and then restore it later using a provided thunk. It is designed for testing scenarios where mocking object properties is necessary, such as when testing code that relies on getters, setters, or other property behaviors. This library is particularly useful for JavaScript developers writing unit tests who need to isolate and control object property behavior.
