Perfecto integrates with and supports the IDEs, device platforms, and test frameworks specified here.

Note: The Perfecto UI requires a resolution of at least 1366 x 768 pixels. Resizing windows may have unexpected results.

With the latest version of Perfecto, automation testing is supported on the device platforms listed in this section.

Important: Based on the deprecation policy, Perfecto no longer supports older versions of the mobile OS. For details, see Suspension of support policy | Mobile device OS.

Perfecto supports iOS versions 10 to 14.5 Beta 7. For details about support limitations, see iOS Support Updates.

Perfecto supports Android versions 6 to 11 GA + "Security Update". For details about support limitations, see Android Support Updates.

In addition to a large set of mobile devices, the Perfecto Continuous Quality Lab provides a set of desktop-web environments for testing web applications. The web environments are characterized by:

  • Operating system, such as Windows 8.1 or MacOS Sierra
  • Browser version, such as Chrome v62, Firefox v58, or Safari v10
  • Screen resolution to support testing responsive web applications
  • Browser location setting, either US EastAP Sydney, or EU Frankfurt

The web device is presented to the test script as a virtual machine, hosted by the Perfecto CQ Lab. Normal initialization for the latest version combinations of the VM is approximately 7-10 seconds.

Supported platforms

Use the browserVersion capability to select the version of the browser to configure in your desktop web device.

You can follow the browser version roadmaps at the following links:

  • IE and Edge browsers are configured to disable the popup blocker.
  • Some Windows versions run on Windows Server, as listed above.
  • Chrome version 82 was skipped by Google. It is not available.
  • Edge version 82 was skipped by Microsoft. It is not available.

Due to Microsoft licensing issues, its Microsoft Server counterpart is supplied when you request a desktop edition. This does not affect the view or the input needed in the capabilities, but it entails the usage of slightly different libraries.

Screen resolutions

  • 1024x768 (default)
  • 1280x1024
  • 1366x768
  • 1440x900

Mac web sessions are created using physical Mac machines installed at your Perfecto CQ Lab.

Note: Mac web sessions may require longer initialization than Windows-based web sessions.

Perfecto's Selenium web testing is supported according to the lists below.

  • Except for Visual Analysis commands, Perfecto's extensions are currently not supported for desktop web testing.
  • When creating a session with the platformName capability set to Mac, the location capability is mandatory.
  • Mac web sessions are created on real machines. This limits their number and type to the Mac machines installed on-site (CQ Lab).

The following operations are not currently supported on devices with the specified configurations:

That latest Perfecto version supports Selenium/Appium automation scripts based on the following server and client versions:

iOSAndroidDesktop webVirtual devices

Client: 5.0.4 - 7.3.0

Server: 1.20.2*

Client: 5.0.4 - 7.3.0

Server: 1.20.2


Server: 1.12.0 or later. For best performance, we recommend that you work with version 1.15 or later.

Client: Versions compatible with the Appium server version


Client: 3.6 - 3.141.59

Client: 3.6 - 3.141.59


  • Windows 7: 3.4.0, 3.8.1
  • Windows 8 and 10: 3.4.0, 3.8.1, 4.0.0
  • macOS: 3.4.0, 3.14.0, 3.141.59

Client: Versions compatible with the Selenium server

Client: Versions compatible with the selected Appium client version

* As a best practice, we recommend that you select only the version of the Appium client to use and let the natural dependency and compatibility between Appium server and Selenium client versions take care of the rest. If you need to select a specific Selenium client, you must make sure that the client version is compatible with the selected version of the Appium client.
