How to locate a component in nested shadowroots -- polymer in electron

[seth]

Hi everyone!  I'm just dipping into TestComplete and I'm not having much luck figuring this particular issue out.  My project is a polymer/redux front end thats wrapped in Electron.  I'm trying to write some automated tests but am having a problem digging buttons and other components buried within nested shadowroot nodes.

I have enabled support for web components in Web Testing and I can get properties for objects that are one shadowroot deep, but cannot get any properties for objects deeper than that first shadowroot node.  The result I get back is that the object doesn't exist, though it most certainly does exist and function for the user.

Good morning Sonya and thanks!  I actually found that NameMapping is useful but the nameMapping engine doesn't always locate the object and assign a name.  I've found mini work arounds but I think as I have to get deeper into the document, those workarounds won't work anymore.

My best workaround so far is to match the properties CustomObjectTypelook with innerHTML under the Chrome properties in Advanced view within Object Spy.  This also requires me to search for the parent object by FullName, which gets a little ugly.  If there is a better, faster, smarter way, I'd love to hear it  🙂

There's a lot of setup and other information here:

Have you been through all this?

Hi,

Also the https://support.smartbear.com/testcomplete/docs/app-testing/web/web-components/shadow-dom.html help article describes Shadow DOM support in TestComplete. I believe you've already read it, haven't you?

I did not work with (multi-level) shadow DOM, so can suggest nothing better at the moment but to contact Support via the https://support.smartbear.com/testcomplete/message/ form and ask them if multi-level shadow DOM is supported in TestComplete.

Shadow DOM is a new DOM feature that helps you build components. Shadow DOM lets you place the children in a scoped subtree, so document-level CSS The host has a property called shadowRoot that refers to the shadow root. child-element renders its light DOM children inside this div --> <slot id="child-slot">.
