Contributions summary:Nestor primarily contributed to enhancing the unit testing capabilities of the Jenkins pipeline unit testing framework. They added a `verify` method, similar to Mockito's, to assert method calls within tests and implemented exception handling for failed verifications. Further contributions include refactoring and extending the `InterceptingGCL` class, with a focus on default closures, improving readability, and ensuring bindings are accessible in shared library contexts to support thorough testing. Additionally, the user added tests to validate the functionality of shared libraries.
