## Firefox
Automated testing works for Firefox with Linux and Windows and Mac, using both Selenium 1 and (preferably) Webdriver.
Automated testing works with Firefox on Linux, Windows and Mac using Webdriver.
## Safari
Automated testing works for Safari on Windows, using Selenium 1. Webdriver does not provide a driver for Safari. See [http://code.google.com/p/selenium/issues/detail?id=599](http://code.google.com/p/selenium/issues/detail?id=599)
It is currently the fastest driver, the most convenient to use and it requires
no specific configurations or workarounds.
For details, see [http://code.google.com/p/selenium/wiki/FirefoxDriver](http://code.google.com/p/selenium/wiki/FirefoxDriver).
## Opera
Automated testing works with Opera on Linux, Windows and Mac using Webdriver.
Note that MathJax support for STIX fonts is disabled for that browser, so you
can only use TeX fonts. On Windows, use Opera >= 11.60 to avoid issues with the
program files directory being unwritable. Otherwise it is one of the fastest
driver and one of the most convenient to use.
For details, see [http://code.google.com/p/selenium/wiki/OperaDriver](http://code.google.com/p/selenium/wiki/OperaDriver)
and [https://github.com/operasoftware/operadriver#readme](https://github.com/operasoftware/operadriver#readme).
## Chrome
Automated testing for Chrome works on Linux and Windows, using Selenium 1 and Webdriver. However, the Chrome driver on Linux has a serious limitation at the moment: it is not possible to take screenshots ([http://code.google.com/p/chromium/issues/detail?id=89777#c4](http://code.google.com/p/chromium/issues/detail?id=89777#c4)). Hence it is recommended to use Selenium 1 when you execute a set of tests that includes visual reftests and the faster Webdriver API otherwise.
Automated testing works with Chrome on Linux, Windows and Mac, using Webdriver.
However, the Chrome driver on Linux has a serious limitation at the moment:
[it is not possible to take screenshots](http://code.google.com/p/chromium/issues/detail?id=89777#c4).
Hence, when you execute a set of tests that includes visual reftests, you must
use the Selenium 1 API instead, which seems two to three times slower that the
Webdriver API. Otherwise, the speed should be comparable to Firefox or Opera.
To use Webdriver, a ChromeDriver server should be installed on the test machine. See
[http://code.google.com/p/chromium/downloads/list](http://code.google.com/p/chromium/downloads/list)
An additional configuration is required to use the Webdriver API: you must
install the [ChromeDriver server](http://code.google.com/p/chromium/downloads/list)
on each test machine.
For details, see [http://code.google.com/p/selenium/wiki/ChromeDriver](http://code.google.com/p/selenium/wiki/ChromeDriver).
## Internet Explorer
Automated testing works for Internet Explorer using Selenium 1 and Webdriver. However, selection of Internet Explorer's compatibility mode is not implemented yet when Webdriver is used (default mode is Quirks). See [http://code.google.com/p/selenium/issues/detail?id=2564](http://code.google.com/p/selenium/issues/detail?id=2564)
Automated testing works with Internet Explorer on Windows, using Webdriver.
However it does not have all the benefits of other drivers. For example, the
selection of the document mode is currently implemented using the Selenium 1
API and Java keyboard events. This is not really reliable but is the best we
can do until
[issue 2564](http://code.google.com/p/selenium/issues/detail?id=2564)
is fixed. Also this driver is a bit slower and only one instance at once can be
executed on a given machine.
IE9 with Selenium 1 is very slow and timeout happens too often!
To use Webdriver, you may need to do some
[specific configurations](http://code.google.com/p/selenium/wiki/InternetExplorerDriver#Required_Configuration).
To use Webdriver, you should follow the instructions in "Required Configuration":
[http://code.google.com/p/selenium/wiki/InternetExplorerDriver](http://code.google.com/p/selenium/wiki/InternetExplorerDriver)
For details, see [http://code.google.com/p/selenium/wiki/InternetExplorerDriver](http://code.google.com/p/selenium/wiki/InternetExplorerDriver).
On IE 7 or higher on Windows Vista or Windows 7, you must set the Protected Mode settings for each zone to be the same value. The value can be on or off, as long as it is the same for every zone. To set the Protected Mode settings, choose "Internet Options..." from the Tools menu, and click on the Security tab. For each zone, there will be a check box at the bottom of the tab labeled "Enable Protected Mode".
## Safari
Unlike other WebDriver classes, there should only ever be a single InternetExplorerDriver instance at once on a given machine.
Automated testing works with Safari on Windows, using Selenium 1. I got a proxy
issue on the DSI machine that prevented to test it on Mac, so I can't say
anything in that case.
## Konqueror
However Selenium 1 is slow.
An [experimental driver](http://code.google.com/p/selenium/wiki/SafariDriver)
exists but seems to have strong inconveniences like the need to
register to Apple's developer program to generate a signature for the
driver extension. Apparently, a Mac platform is needed to do so. I have not
tested this driver yet.
<del>Automated testing works for Konqueror on Linux, using Selenium 1</del>. Webdriver does not provide a driver for Konqueror.
Note that MathJax support for STIX fonts is disabled for that browser, so you
can only use TeX fonts.
**It fails with the latest Selenium version, last time I tried!**
For details, see [http://code.google.com/p/selenium/wiki/SafariDriver](http://code.google.com/p/selenium/wiki/SafariDriver)
## Opera
## Konqueror
Automated testing may work with Konqueror on Linux, using Selenium 1. However
this support seems broken with recent versions of Selenium. Also, Webdriver does
not provide a driver for Konqueror.
Automated testing works for Opera on Linux/Windows, using Webdriver. (I was also able to make Selenium 1 work with Opera, but it is better to use the Webdriver interface).
## Android
Note that MathJax support for STIX fonts is disabled with Opera, so it's preferable to use TeX fonts for testing.
Automated testing works with Android, using Webdriver. I have only tested it
using an emulator on Linux, not a real Device.
On Windows Vista and 7 the program files directory is not writable. If you run Opera 11.5x from this location you will get an error beginning "Opera has failed to access or upgrade your profile". To solve that issue, you have to install Opera in a custom location and set the OPERA_PATH accordingly. See [https://github.com/operasoftware/operadriver#readme](https://github.com/operasoftware/operadriver#readme)
The documentation says to setup port forwarding to make the android server
available at http://localhost:8080/wd/hub. However, this address seems to be
only reachable from the machine on which the emulator is running. Consequently,
I've only been able to make it work when the test runner and Android emulator
are on the same machine.
## iPhone
Similarly, the address http://localhost/ does not seem reachable from the
emulator, so I've used http://devel.mathjax.org instead to get the test suite
pages and MathJax scripts.
Automated testing for iPhone would require a Mac (and Webdriver) and thus I have not tested it yet.
See [http://code.google.com/p/selenium/wiki/IPhoneDriver](http://code.google.com/p/selenium/wiki/IPhoneDriver)
Obviously, the screen resolution is lower on a mobile, so that may be
problematic for some visual reftests. Android can however be used with larger
resolutions.
## HTMLUnit
For details, see [http://code.google.com/p/selenium/wiki/AndroidDriver](http://code.google.com/p/selenium/wiki/AndroidDriver)
HTMLUnit is a GUI-less browser which uses the Rhino JavaScript engine. Automated testing works for it on Linux/Windows using Webdriver. Obviously, visual reftest are not relevant for this configuration and thus are skipped.
## iOS
## Android
Automated testing may work with iOS, using Webdriver. It seems to require a Mac
and possibly a iOS device. I have not tested it yet.
Automated testing works for Android (on Linux), using Webdriver. I have only tested it using the emulator (not real Device).
See [http://code.google.com/p/selenium/wiki/AndroidDriver](http://code.google.com/p/selenium/wiki/AndroidDriver)
For details, see [http://code.google.com/p/selenium/wiki/IPhoneDriver](http://code.google.com/p/selenium/wiki/IPhoneDriver)

Automated testing works on Linux/Windows/Mac using Webdriver.
Similarly, the address http://localhost/ does not seem reachable from the emulator, so I've used http://devel.mathjax.org instead to get the test suite pages and MathJax scripts.
HTMLUnit is a GUI-less browser which uses the Rhino JavaScript engine. The
Selenium documentation recommends it for fast testing. Obviously, visual
reftest are not relevant for this configuration and thus are skipped. MathJax
also uses features specific to real browsers and so even non-visual tests may
fail or be irrelevant. Hence this driver does not seem really useful for our
purpose.
Obviously, the screen resolution is lower on a mobile, so that may be problematic for some visual reftests.
