Test Driven Development with a testing framework like jest or mocha

Hi, I have difficulties to test processing (p5.js) modules.
Any hints to **BDD or TDD workflows** with p5.js modules are welcome. I studied the example at [tdd](https://p5js.org/learn/tdd.html ) but can't understand how it could help me testing modules with p5.Table functions.

I just post a question at [stack overflow ](https://stackoverflow.com/questions/76619451/tdd-test-driven-development-with-a-test-framework-like-jest-or-mocha-to-test-p )with a code and test example and would be happy to provide further details on my query if needed.
