We have created a test class for ExpectNewServiceUser and a test class for ExpectNewService . In the ExpectNewServiceUser class, we have created an instance of ExpectNewService class and used it in the useService() method. In the ExpectNewServiceUserTest class, we have mocked the ExpectNewService class and passed it to the ExpectNewServiceUser class. In the ExpectNewServiceTest class, we have created an instance of the ExpectNewService class and called the doSomething() method. We have verified that
