For the records, Async.js ships with a native map method, not sure how I missed it :x

So the code is even shorter:

describe("moods tests", function() {
    var moods = [
        "2013-02-01:n1k0:sunny"
      , "2013-02-02:n1k0:cloudy"
      , "2013-02-03:n1k0:stormy"
      , "2013-02-04:n1k0:rainy"
      // … we could add many more
    ];

    it("should do something useful with moods", function(done) {
        async.map(moods, store, function(err, storedMoods) {
            assert.ifError(err);
            // now let's test stuff with stored moods
            done();
        });
    });
});

I could have kept the load() function in order to make the actual test code even shorter but I wouldn't really see the point.
