Could you please a unit test for this change?

In fact, in the integration test, we already test this case.

In generateCreateFunctionCommand(), we add the command as follows:

        if (batchBuilder != null) {
            commandBuilder.append("--batch-builder" + batchBuilder);
        }

And in create different language functions, we will use generateCreateFunctionCommand res to test different case.

        switch (runtime){
            case JAVA:
                command = generator.generateCreateFunctionCommand();
                break;
            case PYTHON:
            case GO:
                generator.setRuntime(runtime);
                command = generator.generateCreateFunctionCommand(functionFile);
                break;
            default:
                throw new IllegalArgumentException("Unsupported runtime : " + runtime);
        }
