Using the ParameterResolver Extension
Explore how to implement the ParameterResolver extension in JUnit 5 to enable dynamic parameter injection for test methods and constructors. Understand creating custom resolvers by overriding supportsParameter and resolveParameter methods, and learn how to apply these extensions with @ExtendWith to improve test modularity and flexibility.

The ParameterResolver extension allows us to resolve a constructor or method parameter of a test.
We have to create a class that extends the ParameterResolver interface. This allows us to write an extension to access the parameter resolution access point.
