Known Issues - Embedded frameworks and headless browsers
This topic lists known issues when using UFT to test Web apps in embedded frameworks and headless browsers.
UFT has the following known issues when working with CEF, Electron, and NW.js frameworks.
|Earlier Chromedriver versions||
If you are using a version of the Chromium framework for your Java CEF, CEF Sharp, or AdobeCEP application that is older than 2.40, you must modify the Chromedriver version installed with UFT to match your application's version.
In the <UFT installation folder>/bin/WebDriver directory, replace the chromedriver.exe file with a the version that matches your application.
For more details, see http://chromedriver.chromium.org/downloads.
The following features are not supported when working with CEF, Electron, or NW.js apps:
|Non-supported objects and methods||
The following objects and methods are not supported when working with CEF, Electron, or NW.js apps:
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.
Only standard, bitmap, and text/text area checkpoints are supported.
|Electron objects only||
UFT supports applications in the Electron framework only when run in sandbox mode.
For example, launch your application with the --enable-sandbox command.
|CEF objects only||
To enable UFT to recognize objects in a CEF application:
Make sure that the windows class name of the application's web element container begins with Chrome_WidgetWin.
|Localized versions of UFT||
When working in localized versions of UFT, connecting to an application that includes Chromium Embedded Framework or Electron objects via the localhost may have errors.
In such cases, use the 127.0.0.1 IP address instead.
|Ending processes manually||
You may need to end the WebDriverHost.exe or chromedriver.exe processes manually in the following situations:
In such cases, you must end these processes manually to avoid unexpected behavior when working with the CEF / Electron / NW.js 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.
CEF Sharp only:
When working on CEF Sharp, spying is not supported.
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 to uniquely identify each window.
UFT has the following known issues when working with Shadow DOM.
Testing apps developed with Shadow DOM is supported only in Chrome.
Testing apps developed with Shadow DOM is supported only when the Shadow DOM open development mode was used.
The following properties are not supported:
|Web 2.0||UFT's support for Shadow DOM does not include test objects created with Web 2.0 technologies.|
UFT has the following known issues when working with PhantomJS and Headless Chrome.
|Supported Chrome versions||Headless Chrome is supported only in Chrome versions 60 or higher.|
|Recording||Recording on PhantomJS toolkits or Headless Chrome is not supported.|
|Data driving||If you are data driving your test, we recommend adding a Browser.CloseAllTabs method to the end of each iteration to prevent failures in your test runs.|
The following features and objects are not supported when working with PhantomJS apps:
|Unsupported test objects and methods||
Headlesss Chrome only:
WebAgGrid and UIGrid objects
PhantomJS / Headless Chrome:
The following test object methods and application objects are not supported:
The Mouse replay type is not supported. Use Event replay type instead.
|Running tests||Maintenance Run Mode is not supported.|
