Parameterized Tests Overview: Allows running a single test with multiple input parameters without much boilerplate code. Useful for testing enums or other collections.

• Example with an enum Feature: Different features with premium and free status. Without parameterized tests, multiple individual tests were needed. With parameterized tests, one test can be used for each type of feature.
• Benefit in Test Navigator: When a test fails, it shows clearly which argument caused the failure.

Testing with Multiple Argument Collections: Can run a test with multiple collections as arguments.

• Example with free tries for premium features: A test to check the number of tries within the free limit. Using multiple collections, it can handle different features and their try limits.
• Handling changes in limits: If a premium feature's limit changes, it's easier to update the argument collections in the parameterized test.
