The following features are not supported when working with CEF, Electron, JxBrowser, NW.js, or Microsoft Edge WebView2 apps:

• Navigate and Learn

• Drag and Drop

• Active Screen

• Web options (Tools > Options > GUI Testing tab > Web node)

• Low-level recording

On JxBrowser, running tests on multiple tabs or windows is not supported.

The following objects and methods are not supported when working with CEF, Electron, JxBrowser, NW.js, or Microsoft Edge WebView2 apps:

• * about://* pages

• * chrome://* pages

• Browser dialog boxes (like Alert, Confirm, Prompt)

• Modal or modeless dialog boxes

• WebFile test objects

• ViewLink test objects

• WebAgGrid and WebUIGrid objects

• WebXML test objects

• Browser methods

  Note: On CEF applications, the following browser methods are not supported: 

  OpenNewTab, Close, ClearCache, DeleteCookies, CloseAllTabs, FullScreen, Maximize, Minimize, DialogExists, HandleDialog, Quit, Restore

  All other browser methods are supported only when running tests.

Only standard, bitmap, and text/text area checkpoints are supported.

While recording, if a page navigation script is displayed after the page is fully loaded, and you continue to record directly, you may end up with errors in your script.

To ensure that the correct script is recorded with no errors, wait until the navigation step is fully recorded before continuing.

If your navigation step is not recorded at all, add it manually.

Electron only:

When spying on two Electron windows that have identical sizes and titles, resize one of the windows before spying and adding objects.

This enables UFT One to uniquely identify each window.

When working with Web extensibility-based test objects, including UFT One's Web 2.0 Add-in test objects, highlighting does not always highlight the expected area.

UFT One supports applications in the Electron framework only when run in sandbox mode.

For example, launch your application with the --enable-sandbox command.

To enable UFT One to recognize objects in a CEF application:

By default, UFT One expects the windows class name of the application's web element container to begin with Chrome_WidgetWin.

To support cases that don't start with Chrome_WidgetWin: Modify the HKEY_CURRENT_USER\Software\Mercury Interactive\QuickTest Professional\MicTest\Packages\WebPackage\Settings\CEFWindowClassPrefix registry key value. Enter the windows class name prefix used in your application's web element container.

When working in localized versions of UFT One, connecting to an application that includes CEF, Electron, or JxBrowser objects using localhost may result in errors.

In such cases, use the 127.0.0.1 IP address instead.

Microsoft Edge WebView2 does not enable automatically playing audio and video files. Therefore, when you run the WebAudio.Play and WebVideo.Play methods for the first time on a Microsoft Edge WebView2 application, these methods do not work.

Workaround: Before running the WebAudio.Play and WebVideo.Play methods, manually play the audio or video files on the application first.

You may need to end the WebDriverHost.exe, chromedriver.exe, or msedgedriver.exe processes manually in the following situations:

• If UFT One was connected to an incorrect port

• If the application was not closed correctly.

In such cases, you must end these processes manually to avoid unexpected behavior when working with the CEF / Electron / JxBrowser / NW.js / Microsoft Edge WebView2 application.

Tip: Add the WebUtil.DetachRemoteDebugging method to your test to end these processes during the test. Define the method with the application's IP address and port.

For more details, see the WebUtil object in the Utility section of the UFT One Object Model Reference for GUI Testing.

The following features and objects are not supported when working with PhantomJS apps:

• Highlight in Application

• Navigate and Learn

• Add Objects to Local button in the Object Spy
