Unit test for unsigned 24-bit int accessors for Javascript DataViews.

test-DataView_Uint42Accessors.js

describe("DataView", function() {
	it("should implement Uint24 accessors", function() {
		var i, n, buf, dv;
		buf = new ArrayBuffer(3);
		dv = new DataView(buf);
		n = Math.pow(2, 24);
		// this should give us decent coverage without trying every single number, which takes forever
		for(i = 1; i < n; i += 111) {
			dv.setUint24(0, i);
			dv.getUint24(0).should.equal(i);
		}
	});
});

This is a unit test for https://gist.github.com/nphyx/5c19ef4cdb9774d87e0d
Test environment is Mocha+Chai.

For the record I have run this test for the full range of possible values, it just takes a long time.
