I was researching a framework to test my new code (and that could also be used
to test the existing C API if needed). Currently src/gie.c has ad-hoc testing,
but it is really limited feature-wise: no nice error message (returns error
code), no way to make a testcase go on even if a test check fails, etc...
So a dedicated framework seems a better idea, and I've found catch2 :
One of its main feature it is a header only testing framework, which means we
can embed it easily in proj source tree, which is practical compared to other
frameworks I've considered ( googletest, cppunit, etc... ).
The tut framework used by GDAL and GEOS
( http://mrzechonek.github.io/tut-framework ) would also enter this category
of header(s) only, but it has not as much as activity than catch2.
There's also Boost.Test, but I was a bit afraid with the boost name in it
(although apparently it has a standalone mode).
Example of tests I've just written with catch2 (just a minimalistic use of the
I'm not particularly calling for a flame debate on the suject, just wanting to
mention this finding.
