Google launched Sputnik – JavaScript Conformance Test in June’ 2009. This test will run over 5000 tests to check the web browser JavaScript conformance. Last week they come up with the updates which any one can use easily and the results are quiet interesting!
Opera (78 failures) and Safari (159 errors) web browsers beat Google’s own Chrome (218 errors) browser in the test. Firefox is close behind with 259 errors, while Internet Explorer is the outlier with 463 errors.
While much of the focus on JavaScript is about speed, Sputnik is interesting because it focuses on conformity, making it more like the Acid3 test, which tests web standards compliance. Chrome, Safari, and Opera have all passed Acid3; with Firefox getting very close (94/100 for Firefox 3.6). IE, meanwhile, again lags behind with just 20/100 for IE8. And even the new IE9 preview only scores 55/100.
