How does Dependency Injection improve unit testing in Java applications?
DI improves testing by allowing you to pass parameters directly into a class's constructor, enabling you to avoid the need for setters or other configuration techniques.
Thatâ€™s partially correct. DI helps in unit testing by decoupling dependencies, but it's not just about passing parameters into constructors.
Can you explain how using Spring's @Autowired annotation helps with DI in testing?
