Browser based Testing on Firefox Version 47 Now Available Inside CQ Lab

Perfecto Announces First-Day Support for FireFox Version 47

/, Responsive Web Design/Perfecto Announces First-Day Support for FireFox Version 47

With the digital market changing every day, Perfecto always aims to give digital developers and testers immediate access to the newest browser and mobile operating system releases. This accessibility makes it easy teams to quickly perform mobile and browser testing as soon as new releases are available.

Desktop browser updates for FireFox and Chrome, in particular, can be tricky. They’re often automatically updated on PCs without alerting users, and that may inadvertently cause issues with overall app’s performance. As a result, organizations that deploy web apps, mobile web apps or responsive websites (RWD) must always test on the latest, “official”, browser version before that update is automatically made.

Mozilla released a new version of the FireFox browser (Version 47), and this release has various compatibility issues with the Selenium test automation framework that prevents testing teams from executing their existing Selenium scripts against the new version. Below is an example of the errors they are seeing:

Browser Based Testing Will Prevent Testing Errors

Until the issue is resolved, customers can reduce the risks of escaped defects by using the Perfecto digital testing lab to perform remote manual testing on FireFox version 47 against various Windows OS versions, including XP, 7, and 8.1.

Mobile and Browser Based Testing from One Digital Quality Lab

The mandate for app and website developers is clear: Break down the silo between web and mobile testing. One digital quality lab will allow teams to test their mobile, web and desktop apps across multiple platforms. Team members can launch multiple mobile devices and browsers, and then automate a single test script across them – giving you the ability to see how each platform responds to the test. In addition to performing functional tests, the Perfecto lab lets you perform real-user condition testing against various environments such as user location, network type and speed, and apps running the background.
