Access seed in test

[sdressler]

I was trying to get the seed inside the tests, because they are using random number generators themselves. Usually it is not std::rand but std::minstd_rand with some specific distribution. On the other hand, the classes under test also take a seed.

I have seen, that one can grab the current context with getCurrentContext and then access the configuration. But I am not able to compile it due to linkage errors, e.g.

const uint64_t seed = Catch::getCurrentContext().getConfig()->rngSeed();

will lead to multiple definition ofCatch::signalDefs', mostly because I had to includecatch_runner.hpp` which I think is not intended.

Maybe there already is a correct way to capture the seed inside the test, otherwise it would be a nice feature :-)

as of v1.2.1-develop.2 you can now get the seed by calling Catch::rngSeed().

Awesome :-)
