MOCK_METHOD arguments limit of 15?

[PiotrNycz]

Has MOCK_METHOD macro hard limit on number of arguments to 15?
If yes, where is that documented?
If not documented - then maybe it should be.
The compilation error is pretty hard to understand...

Looks it has:
gmock/internal/gmock-pp.h

// Requires: the number of arguments after expansion is at most 15.
#define GMOCK_PP_NARG(...) \
  GMOCK_PP_INTERNAL_16TH(  \
      (__VA_ARGS__, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0))

but just want confirmation this is desired behavior - and what about documenting it?

Yes upto 15. This article mentions that the MOCK_METHOD macro traditionally has a hard limit of 10 arguments due to internal constraints, but an extension was created to allow up to 15 arguments.

I agree with you. It's better to documented with this limit in the official documentation to help to understand
