params

params should return an object with two keys: height, width

var req = {
    query: {
        height: 600,
        width: 600
    }
};
var result = util.params(req);
assert.equal(2, Object.keys(result).length);

params should return an object with the keys: height = 600, width = null

var req = {
    query: {
        height: 600,
        width: '6dsf00'
    }
};
var result = util.params(req);
assert.equal((Object.keys(result).length == 2),(result.width == null));

params should return an object with the keys: height = null, width = 600

var req = {
    query: {
        height: 0,
        width: 600
    }
};
var result = util.params(req);
assert.equal((Object.keys(result).length == 2),(result.height == null));

params should return null

var req = {
    query: {}
};
var result = util.params(req);
assert.equal(null, result);

relativePath

relativePath should return a path without leading slash

var path = '/Content/Images/car.jpeg';
var result = util.relativePath(path);
assert.equal(true, (result.charAt(0) !== '/'));

parseReqUrl

parseReqUrl return an array

var path = 'content/image.jpg';
var result = util.parseReqURL(path);
assert.equal("object", typeof(result));

parseReqUrl return an array with two keys

var path = 'content/image.jpg';
var result = util.parseReqURL(path);
assert.equal(2, result.length);

assetAvaialble

assetAvaialble should callback when asset is available

var path = 'tests/test.png';
util.assetAvailable(path, function (err) {
    if (err)
        assert.equal(true, false);
    assert.equal(true, true);
});

assetAvaialble should callback with error when asset is unavailable

var path = 'tests/test.jpg';
util.assetAvailable(path, function (err) {
    if (err)
        assert.equal(true, false);
    assert.equal(true, true);
});
