nicob87 opened a new pull request #684: WIP: (Work In Progress) DISPATCH-1568: 
using doctest 
URL: https://github.com/apache/qpid-dispatch/pull/684
 
 
   - Demo using the library that Jiri Daněk suggested in the issue, it seems to 
be a very nice option for several reasons, it is an evolution of catch2, 
compile time significantly smaller, support nested "subcases" which simplifyes 
setup and teardown, it is a single header file, and others.
   see: https://github.com/onqtam/doctest
   
   - jira: https://issues.apache.org/jira/browse/DISPATCH-1568 
   
   - Commit history will be fixed. a lot of junk for now.
   
   - To run the demo, just:
   
   ```
   [nbrignon@localhost build (nb-doctest)]$ cmake ..
   ...
   [nbrignon@localhost build (nb-doctest)]$ make c_unittest
   ...
   ```
   - and then we can execute the binary directly:
   
   ```
   [nbrignon@localhost build (nb-doctest)]$ ./tests/c_unittest 
   [doctest] doctest version is "2.3.6"
   [doctest] run with "--help" for options
   
===============================================================================
   [doctest] test cases:      5 |      5 passed |      0 failed |      0 skipped
   [doctest] assertions:     15 |     15 passed |      0 failed |
   [doctest] Status: SUCCESS!
   ```
   - or debug it:
   ```
   [nbrignon@localhost build (nb-doctest)]$ gdb ./tests/c_unittest 
   ...
   (gdb) b safe_snprintf
   Breakpoint 1 at 0x408330
   (gdb) run
   ...
   Breakpoint 1, safe_snprintf (str=str@entry=0x7fffffffcd00 " 
\313\371\367\377\177", size=size@entry=19, format=format@entry=0x4228d2 
"something")
       at /home/nbrignon/qpid-dispatch/src/router_core/terminus.c:89
   89      size_t safe_snprintf(char *str, size_t size, const char *format, 
...) {
   ```
   
   - or execute it through ctest:
   ```
   nbrignon@localhost build (nb-doctest)]$ ctest -VV -R c_unittest
   ...
   test 1
       Start 1: c_unittest
