A BDD style unit testing framework for C++11

This is still an experiment in using C++11. I ended up with a framework similar to RSpec, Mocha or Jasmine from other environments.

bandit is a test framework. It is (going to be) agnostic of the assertion framework to use. Right now it uses snowhouse for its internal testing. Snowhouse is the assertion framework used by igloo.

As bandit makes heavy use of lambdas it does not have to do a whole lot of preprocessor magic to get things done. The only macro right now is the go_bandit() construct which is used to register which specs to run.

This is a complete test application written in bandit:

#include <bandit/bandit.h>
using namespace bandit;

#include <snowhouse/snowhouse.h>
using namespace snowhouse;

go_bandit([](){

    describe("fuzzbox:", [](){
      guitar_ptr guitar;
      fuzzbox_ptr fuzzbox;

      before_each([&](){
        guitar = guitar_ptr(new struct guitar());
        fuzzbox = fuzzbox_ptr(new struct fuzzbox());
      });

      before_each([&](){
        guitar->add_effect(fuzzbox.get());
      });

      it("starts in clean mode", [&](){
        AssertThat(guitar->sound(), Equals(sounds::clean));
      });

      describe("in distorted mode", [&](){

        before_each([&](){
          fuzzbox->flip();
        });

        it("sounds distorted", [&](){
          AssertThat(guitar->sound(), Equals(sounds::distorted));
        });
      });
    });

});

int main(int argc, char* argv[])
{
  return bandit::run(argc, argv);
}
