test.cpp needs to return non-0 if tests fail

[bast]

Right now the code looks like it always returns 0 but this is surprising for any test framework that would want to run the executable. I tried with CTest but basically any other would behave the same way.

The expectation is that the binary returns 0 if all tests succeed and non-0 if there are failures. The return code can for instance be defined as number of failing tests.

If it always returns 0, then test frameworks will report that it passed because they only look at return code.

This is the relevant line:

reference-implementation/test/test.cpp

Line 40 in 08790b5

return 0;
