Linking of tests when app itself has a main

[Rene Beckmann <be...@itemis.de>]

Hello,

I hope this is the right place to ask this, I'm very sorry if not.
I am currently experimenting with Apache MyNewt, have written a tiny app
(apps/simple) and created a test suite (apps/simple/test) for it.
The apps/simple/test/pkg.yml contains "apps/simple/" as pkg.deps.
The problem is that my app itself contains a main function, as well as the
test suite (guarded by #if MYNEWT_VAL(SELFTEST) ). When running "newt test
apps/simple", newt properly compiles the test, seems to find its main
function, however it happily overrides it with the one found in the main
app, so the test does not run. The test project found in the docs tests a
library, which does not contain a main function, so this is not covered. I
could help myself by using:
#if MYNEWT_VAL(SELFTEST)
#else
int main...
#endif
However, that's neither pretty nor do I believe that this is the correct
way to do it. Maybe someone can point me to something that makes newt
ignore the app's main by default?

Regards,
René Beckmann

Hi René,

unittest framework was developed assuming that apps themselves
would not have test suites. Only individual packages/libraries.

So the method you described is pretty much what you’d need to do.
Or alternatively create a library out of the components you want to
create unittests for.
