More documentation for using Catch

[astamm]

The documentation says:

Symbol Registration

If you've opted to disable dynamic symbol lookup in your package, then you'll need to explicitly export a symbol in your package that testthat can use to run your unit tests.

Could you be more explicit as to how to do this please?
Thanks a lot.

To be more explicit, when I add

extern SEXP run_testthat_tests(SEXP);
static const R_CallMethodDef CallEntries[] = {
  {"run_testthat_tests", (DL_FUNC) &run_testthat_tests, 1},
  {NULL, NULL, 0}
};

to my init.c file, it works fine when I use devtools::check() but devtools::test() fails with the following message:

segfault from C stack overflow

I was wondering whether I exported the run_testthat_tests symbol properly given that in my package I opted to disable dynamic symbol lookup. Link to the package here.
