Random Test Case Generation with Nose Library

This function generates a random test case using the Nose library. It randomly selects a test type (such as assert_equal, assert_not_equal, etc.) and then creates a test function that uses the selected test type to generate a random test.

Technology Stack : Nose

Code Type : The type of code

Code Difficulty : Intermediate
