advice to debug an app

I'm working on a specific application generation a lot of code on the server side.

The process is as follows:

• I write a class with some methods. For example:

  Class MyClass {
      public function foo(){…}
      public function bar(){…}
  }

• I send them to the server
• The server "injects" code in my class. For example:

  Class MyClass {
      /* injected content */
      public function gen(){…}
      /* end of injected content */
  
      /* original content */
      public function foo(){…}
      public function bar(){…}
      /* end of original content */
  }

The question is now: How would you debug this generated code since

• you do not have the generated code in your sources
• you cannot include them in your project since this would result in all your classes being doubled

I know the way this tool works is really surprising, but I cannot use another tool…

Thanks for your feedback.
