Parameterized unittest loaded from json file in Python

I would like load test cases from a json file and perform a parameterized testing , basically I would like to create a TestClass and then execute dynamically all test cases (get from the json file).
I'm using this library:
https://pypi.org/project/parameterized/


This should be the structure:
TestSuite_1
->testcase1
->testcase2
TestSuite_2
-> testcase2
-> testcase3
-> testcase4
