Using a mocking framework ensures that your unit tests are fast, self-contained and deterministic. Fails fast if referenced bean is not found. ES6 classes are constructor functions with some syntactic sugar. Consequently, source code directories for other test types should follow a similar pattern. Mocking is typically used in the construction of isolated unit tests. Just add com. Spock Mock not working for unit test. It enforces BDD at the core and ensures all tests written using the framework follows the BDD conventions. All invocations on the spy that don’t match an interaction are delegated to that object.
