make check - no test ran #767

Symptom: Running make check doesn't run any test on my environment.

$ make check
make check -C test
make[1]: Entering directory '/hbdev/test/ziplib/json/test'
Executing test-json_patch...
===============================================================================
No tests ran

The issue seems to be in test/Makefile

if I replace

TEST_PATTERN ?= "*"

with

TEST_PATTERN ?= ""

The issue seems fixed

OS: Windows 10
Plat: MSYS2 - GNU Make 4.2.1 - gcc version 7.2.0 (Rev1, Built by MSYS2 project)

Thanks
