How to test an RFC module that exists only in remote system?

Question

I'm debugging a solution where a program in one SAP system (A) calls a remote-enabled function module in a different SAP system (B) via RFC connection.

Is there a way to 'test-run' the RFC from A, like we normally do with SE37 for local function modules? The remote function module does not exist in A, so SE37 just gives an error message that the function module does not exist.

I can run the function module in B using SE37, but I need to test it over an RFC connection.

Two options in the calling system:

1. Create a shell ABAP program to call the FM, run in SE38;
2. Create a shell of the FM with just the parameters, run in SE37.

I do not believe there is a way to do this without any programming in the calling system. To generate the test environment in SE37 the transaction needs to know the interface of the FM.
