Java: Constructor vs Field Injection
Answer
Constructor injection enhances testability by allowing easy substitution of dependencies.
Constructor injection simplifies unit testing by making it straightforward to inject mock dependencies into a class. This results in more predictable and isolated tests. For example, when testing an 'OrderProcessor' class, you can easily inject a mock 'InventoryService' to simulate different inventory scenarios without affecting other components.
