        done(null, 1);
    });
    it(\'a

Very much agree with what Louis said, and those are the reasons that Mocha doesn't actually support it. Think of the async method you referenced; if your first test fails you get a waterfall failure across the rest of them.

Your only way to go about it is, as you say, to stick a variable at the top:

describe('some test', function(){
    var value = 0;
    it('should pass a value', function(done){
        value = 5;
        done();
    });
    it('and then double it', function(done){
        console.log(value * 2); // 10
        done();
    });
});
