Chai's be implementation is more like the should.js implementation... be is a language chain. The equivalent for be in chai is equal. Your alternatives are as follows...

expect(true).to.be.true;
expect(true).to.equal(true);

Your welcome to keep this thread for any other differences you find, but this is one I cannot change.

from chai.

The other difference you will likely find is an. In expect.js an is an alias for a, where in chai an is also a language chain. Your alternatives for that particular scenario are as follows...

expect([ 'hello', 'universe' ]).to.be.an.instanceof(Array);
expect({ hello: 'universe' }).to.be.a('object');

This makes sense to me, thanks for the enlightenment. I just need to convert a few existing expect.js tests to the should/chai behavior. I think I can just close this issue.
