To automatically generate services from controllers and their actions, you need to run the GenerateService project.
After execution, for each controller, a service will be created in IntegrationTest.Services.AutoGeneratedBaseOnControllers,and for each action, a corresponding method will be generated within that service.
Additionally, a partial class is created in IntegrationTest.Services.ExtendedServices to allow for further customization and extension.
