Acid3 test is a web test page from the Web Standards Project that checks a web browser's compliance with elements of various web standards, particularly the Document Object Model (DOM) and JavaScript.

If the test is successful, the results of the Acid3 test will display a gradually increasing fraction counter with colored rectangles in the background. The number of subtests passed will indicate the percentage that will be displayed on the screen. This percentage does not represent an actual percentage of conformance as the test does not really keep track of the subtests that were actually started (100 is assumed). Moreover, the browser also has to render the page exactly as the reference page is rendered in the same browser. Like the text of the Acid2 test, the text of the Acid3 reference rendering is not a bitmap, in order to allow for certain differences in font rendering.

Acid3 was in development from April 2007,[1] and released on 3 March 2008.[2] The main developer was Ian Hickson, a Google employee who also wrote the Acid2 test. Acid2 focused primarily on Cascading Style Sheets (CSS), but this third Acid test also focuses on technologies used on modern, highly interactive websites characteristic of Web 2.0, such as ECMAScript and DOM Level 2. A few subtests also concern Scalable Vector Graphics (SVG), Extensible Markup Language (XML), and data URIs. Controversially, it includes several elements from the CSS2 recommendation that were later removed in CSS2.1, but reintroduced in World Wide Web Consortium (W3C) CSS3 working drafts that have not made it to candidate recommendations yet.

Contents

The test

The main part of Acid3 is written in ECMAScript (JavaScript) and consists of 100 subtests in six groups called “buckets”, including four special subtests (0, 97, 98, and 99).[3]

The compliance criteria require that the test be run with a browser's default settings. The final rendering must have a 100/100 score and must be pixel-identical with the reference rendering.[6] On browsers designed for personal computers, the animation has to be smooth (taking no more than 33 ms for each subtest on reference hardware equivalent to a top-of-the-line Apple laptop) as well,[7] though slower performance on a slow device does not imply non-conformance.[8]

To pass the test the browser must also display a generic favicon in the browser toolbar, not the favicon image from the Acid3 web server. The Acid3 server when asked for favicon.ico gives a 404 response code, but with image data in the body. This tests that the web browser correctly handles the 404 error code when fetching the favicon, by treating this as a failure and displaying the generic icon instead.[9]

When the test is running, the rectangles will be added to the rendered image; the number of subtests passed in the bucket will determine the color of the rectangles.

Note that Acid3 does not display exactly how many subtests passed in a bucket. For example, 3 subtests passing and 4 subtests passing in bucket 2 would both render a black rectangle.

Detailed results

After the Acid3 test page is completely rendered, the capital A in the word Acid3 can be clicked to see an alert (or shift-click for a new window) explaining exactly which subtests have failed and what the error message was. In case some of the 100 tests passed but took too much time, the report includes timing results for that single test. The alert reports the total time of the whole Acid3 test.

In order to render the test correctly, user agents need to implement the CSS 3 Text Shadows and the CSS 2.x Downloadable Fonts specifications, which are currently under consideration by W3C to be standardized. This is required as the test uses a custom TrueType font, called "AcidAhemTest" to cover up a 20x20 red square. Supporting Truetype fonts however is not required by the CSS specification. A browser supporting only OpenType fonts with CFF outlines or Embedded OpenType fonts could support the CSS standard, but fail the test in the Acid3 test. The glyph, when rendered by the downloaded font, is just a square, made white with CSS, and thus invisible.[10]

In addition, the test also uses Base64 encoded images, some more advanced selectors, CSS 3 color values (HSLA) as well as bogus selectors and values that should be ignored.

Development and impact

Google employee Ian Hickson started working on the test in April 2007, but development progressed slowly. In December 2007, work restarted and the project received public attention on 10 January 2008, when it was mentioned in blogs by Anne van Kesteren.[11] At the time the project resided at a URL clearly showing its experimental nature: "http://www.hixie.ch/tests/evil/acid/003/NOT_READY_PLEASE_DO_NOT_USE.html" Despite the notice in the URL, the test received widespread attention in the web-development community. At that time only 84 subtests had been done, and on 14 January Ian Hickson announced a competition to fill in the missing 16.[12]

The following developers contributed to the final test through this competition:

Even before its official release, Acid3's impact on browser development was dramatic. WebKit in particular made progress; in less than a month their score rose from 60 to 87.[13]

The test was officially released on 3 March 2008.[2] A guide and commentary was expected to follow within a few months,[13] but, as of March 2011, only the commentary had been released. The announcement that the test is complete means only that it is to be considered "stable enough" for actual use. A few problems and bugs were found with the test, and it was modified to fix them.[14][15] On 26 March 2008—the day both Opera and WebKit teams announced a 100/100 score—developers of WebKit contacted main Acid3 developer Ian Hickson about a critical bug in the Acid3 that presumably may have forced a violation of the SVG 1.1 standard to pass. Hickson proceeded to fix it with the help of Cameron McCormack, member of W3C's SVG Working Group.[16][17]

Presto and WebKit based browsers

By the end of March 2008, early development versions of the Presto[18][19] and WebKit[17] layout engines (used by Opera and Safari respectively, among others) scored 100/100 on the test and rendered the test page correctly. At the time, no browser using the Presto or WebKit layout engines passed the performance aspect of the test. On 14 March 2009, Iris Browser 1.1.4, a WebKit-based mobile browser, became the first public release of a web browser to pass Acid3,[20][21] and on 7 June, iCab 4.6 for Mac OS X was unofficially announced as the first official release of a desktop browser to pass the test;[22][23] Safari 4, also based on WebKit, passed the next day,[24] although a development version had already passed the previous September.[25][26] By October, Epiphany, another WebKit-based browser, also passed.[27] In May and June, Google Chrome 2.0 and Opera Mobile 9.7 beta[28] displayed a score of 100/100, but did not actually pass; release versions of these browsers passed fully later in the year.[29] Security concerns over downloadable fonts delayed Chrome from passing.[30]

Firefox - 1st time

At the time of Acid3's release, Mozilla Firefox developers had been preparing for the imminent release of Firefox 3, focusing more on stability than Acid3 success. The resulting 3.0 release consequently gained a score of 71.[31] The performance of Firefox was improved in version 3.5, which scores 93/100, and version 3.6, which scores 94/100. At the time it was released, Firefox 4 scored 97/100 because it does not support SVG fonts, which were part of Acid3 at that time. Currently, Firefox 4 scores 100/100 because the SVG font tests were removed from Acid3.

According to Mozilla employee Robert O'Callahan, Firefox does not support SVG fonts because Mozilla considers WOFF a superior alternative to SVG fonts.[32] Another Mozilla engineer Boris Zbarsky claims that the subset of the specification implemented in Webkit and Opera gives no benefits to web authors or users over WOFF, and asserts that implementing SVG Fonts fully in a web browser is hard because it was "not designed with integration with HTML in mind".[33]

Internet Explorer - 1st time

Microsoft, developers of the Internet Explorer (IE) browser, said that Acid3 does not map to the goal of Internet Explorer 8 and that IE8 would improve only some of the standards being tested by Acid3.[34] IE8 scores 20/100, which is much worse than all relevant competitors in their versions from the test's release, and has some problems with rendering the Acid3 test page. On 18 November 2009, the Internet Explorer team posted a blog entry about the early development of Internet Explorer 9 from the PDC presentation, showing that an internal build of the browser could score 32/100 for the Acid3 test.[35]

Firefox - 2nd time

On 2 April 2010, Ian Hickson made minor changes to the test after Mozilla, due to privacy concerns, altered the way Gecko handles the :visited pseudo-class.[36][37]

Internet Explorer - 2nd time

Throughout 2010, several public Developer Previews gradually improved Internet Explorer 9's test scores from 55/100 (on 16 March[38]) to 95/100 (as of 4 August).[39][40][41] General Manager of the IE team Dean Hachamovich argues that striving for 100/100 on the Acid3 test isn't necessary or desirable. He claims the two Acid3 failures are on features (SVG fonts and SMIL animation) that are "in transition".[42]

Firefox and Internet Explorer - 3rd time

On September 17th, 2011, Ian Hickson announced an update to the Acid3 test. He claims that removing the parts of the test that check the implementation of features likely to be removed or heavily modified in future specifications will allow those specifications to change in the way they should, without regard to what Acid3 tests. As a result, the latest versions of Firefox and Internet Explorer achieved a score of 100/100 on Acid3. [43]

Criticism

The current iteration of the test has been criticized for being a cherry-picked collection of features that are rarely used, as well as those that are still in a W3C working draft. Eric Meyer, a notable web standards advocate, writes, "The real point here is that the Acid3 test isn't a broad-spectrum standards-support test. It's a showpiece, and something of a Potemkin village at that. Which is a shame, because what's really needed right now is exhaustive test suites for specifications– XHTML, CSS, DOM, SVG."[44]

"Implementing just enough of the standard to pass a test is disingenuous, and has nothing to do with standards compliance," argues Mozilla UX lead Alex Limi, in his article "Mythbusting: Why Firefox 4 won’t score 100 on Acid3." Limi argues that some of the tests, particularly those for SVG fonts, have no relation to real usage, and implementations in some browsers are created solely for the point of raising scores.[45]

Standards tested

Parts of the following standards are tested by Acid3:

Passing conditions

A passing score is only considered valid if the browser's default settings were used.

The following browser settings and user actions may invalidate the test:

Browsers that pass

The browsers listed here score 100/100 and have no obvious rendering problems. Note that a score of 100/100 indicates only that all the subtests produced the correct result, and does not indicate whether the rendering is correct or whether the subtests passed the performance aspect of the test.

Only stable, public releases are listed here (alpha and beta versions, for example, would not qualify).
