When you are testing. You need to use mocking libraries or Inject your service directly on contructor ie.

public DBContext context;
public IDepartmentAppService departmentAppService;

/// Inject DepartmentAppService here
public DepartmentAppServiceTest(DepartmentAppService departmentAppService)
{
    this.departmentAppService = departmentAppService;
}
