(Incomplete) list of WebEngine features, and how to test for them. Actively maintained list is available on a dedicated documentation page: Qt WebEngine Features
Chromium DevTools
Version: Qt 5.4.0 onwards
Description: Ability to inspect and debug layout and performance issues of any web content.
Documentation: Qt WebEngine Developer Tools and Debugging with WebEngine
How to test: Launch a QtWebEngine app with command line option --remote-debugging-port=[your-port] and use any QtWebEngine-based example browser (from the same version) instance to connect to http://localhost:[your-port]. See documentation for details. Also, widgets' based simplebrowser[1] and quicknanobrowser[2] examples implement opening devtools in a separate view through context menu.
WebRTC
Version: Qt 5.4.0 onwards
Description: Real-Time Communications (RTC) capabilities via simple APIs
Documentation: WebRTC usage
How to test: Set up a webcam / microphone. Open e.g. https://test.webrtc.org/ in simplebrowser[1] for simple test of supported capabilities. Also https://www.webrtc-experiment.com/RecordRTC/ is good to just test screen recording.
HTML5 Geolocation
Version: Qt 5.5.0 onwards
Description: Javascript Geolocation API with QtLocation as a backend
Documentation: HTML5 Geolocation
How to test: QtLocation should be built before QtWebEngine. Using simplebrowser[1], go to http://html5demos.com/geo, and allow the page to find your position. Note that on Windows you need an external GPS receiver connected, see QtPositioning documentation.
Fullscreen
Version: Qt 5.6.0 onwards
Description: Support for viewing content in fullscreen mode.
Documentation: Fullscreen API support
How to test: Use either specialized videoplayer[3] example or just quicknanobrowser[2] and go to youtube.com or vimeo.com and pick any video. Click on the full screen icon to go into fullscreen mode.
Drag & Drop
Version: Qt 5.7.0 onwards
Description: Support for HTML5 drag and drop.
Documentation: Drag and Drop support
How to test: Try any HTML5 drag and drop demo. E.g. this, that or maybe even yon, or w3schools one. Dragging files into the browser is not part of HTML5 but also works. Try also to invoke context menu of simplebrowser[1] or quicknanobrowser[2] and click 'Save page', which will land an offline copy of a page into default downloads directory. Then just drag this file back to browser from a system file explorer. That should open an offline page through file url.
Printing to PDF
Version: Qt 5.7.0 onwards
Description: Support for printing a web page to a PDF file.
Documentation: Print to PDF file
How to test: Use html2pdf[4] and printme[5] examples to test the feature.
HTML5 DRM video
DRM Protected, widevine plugin
Version: Qt 5.7.0 onwards
Description: Support for viewing DRM protected videos.
How to test: QtWebEngine should be built with proprietary codecs enabled (pass '-proprietary-codecs' to configure when building qt). Try and view videos at. e.g. http://demo.castlabs.com/, http://ssdemo04.swankmp.net/ or https://shaka-player-demo.appspot.com/demo/.
Local Storage
Description: Support for HTML5 local storage.
How to test: It seems currently there are only auto-tests in qtwebengine/tests/auto/widgets/qwebenginepage, and no manual tests or examples.
WebGL
Description: Support for HTML 5 WebGL
How to test: Visit http://webglsamples.org/ or https://threejs.org/examples/ and try available demos.
WebSockets
Description: Support for HTML 5 WebSockets
How to test: Try simple online test echo server https://www.websocket.org/echo.html
PPAPI / PDF Viewer
Version: Qt 5.13.0 onwards
Description: Support for PPAPI plugins, and PDF viewer in particular
Documentation: [1]
How to test: Launch SimpleBrowser, QuickNanoBrowser, and make sure that 'Plugins' are enabled. Load a PDF directly by URL, and indirectly embedded in HTML
