Can't map CEF page components
I recently tried to map a CEF page on a desktop application I have installed. I can map the page itself as an object but not the individual components. So far, I've tried to run my application with ...
First step is to confirm whether this is really CEF.
How to isolate / confirm:
- Check the running processes:
- If you see msedgewebview2.exe, the app is using Microsoft Edge WebView2, not classic CEF.
- If the app loads libcef.dll, then it’s classic CEF.
- If it’s WebView2, -injectCefHook will not work (it only applies to classic CEF).
- Seeing only Chrome_RenderWidgetHostHWND and no DOM elements is expected when WebView2 is not properly configured for web testing.
Pointing in the right direction (official docs):
- WebView2 support in TestComplete (requirements and limitations):
https://support.smartbear.com/testcomplete/docs/app-testing/web/webview-two/about.html - Prerequisites for testing WebView2 apps (CDP/debug port requirement):
https://support.smartbear.com/testcomplete/docs/app-testing/web/webview-two/prerequisites.html - Classic CEF support and -injectCefHook (for comparison):
https://support.smartbear.com/testcomplete/docs/app-testing/web/cef/about.html
Summary:
If the app uses WebView2, enable WebView2/Chromium web support and ensure the app exposes a DevTools (CDP) port. If it’s truly classic CEF, then CEF injection applies — otherwise, fallback options are UI Automation or OCR.🤖 AI-assisted response
