Facing problems with tests

Hello devs,

I am currently facing a minor issue when writing tests, which I'm not able
to overcome.
I've written my test cases using the DEFINE_TESTCASE macro and there are no
errors while running a make check.
But when I run a make check, it shows me these warnings:

In file included from apitest.h:26:0,
                 from api_cluster.cc:7:
api_cluster.cc: In function ‘bool test_euclidian_distance1()’:
./harness/testsuite.h:285:38: warning: no previous declaration for ‘bool
test_euclidian_distance1()’ [-Wmissing-declarations]

                                      ^

 DEFINE_TESTCASE(round_robin1, backend)

If I'm not wrong, the collate-test perl script specified in makefile.am is
supposed to expand the macro and add it to the header file, api_all.h and
api_collated.h. But that doesn't seem to happen in my case.
Could I know how to get around this?

Thanks
