Sauce Labs is proud to announce support for Mac OS X, iOS, and Android in their automated and manual testing tools. This allows developers to test websites on mobile devices with ease, using Selenium 1 or WebDriver. Testing on iOS requires specifying the platform as 'Mac 10.6' and selecting an orientation, while Android tests can be run with a similar process but require a different platform and device type capability. With these new features, developers can now run tests on multiple platforms, including mobile devices, making it easier to ensure their websites are compatible across various devices.
