How can we write something like unit tests for testing Azure policies without actually creating resources?

Question

I am currently working on a project where the goal is to test Azure policies before deploying them, the closest I came across this article https://charotamine.medium.com/azure-policy-what-if-you-test-your-policies-5ddb12c95a07 but here too resources are created.

I am wondering if there is some library which takes policy.json and the resource.json as input and runs the policy analysis against the resource.json file. For testing a single policy.json I will create multiple resource.json files, each resource.json file for a specific test case (like a unit test function for a class)

I have tried reading the Python azure sdk for anything that can be of help

I believe you can can use the below "frameworks". They are "an automated testing approach for Azure Policies. The approach is fundamentally based on behavior-driven development (BDD)".
