How to select shadow DOM elements in ASKUI James

Shadow Domain Object Model

The W3C defines the Shadow DOM as an auxiliary tree of DOM nodes. DOM shadow subtrees are associated with an element; however, they do not appear as child nodes of the element. However, subtrees determine the scope of the element. It is possible, for example, that the IDs and styles of shadow DOM subtrees and those of the document overlap, but since the shadow DOM subtree is distinct, the IDs and styles of the shadow DOM subtree are not conflicting.

Shadow DOM basics

Even though the shadow DOM is a simple concept, there are a few nuances that make it appear more challenging than it really is. This section will discuss the essentials. 

Shadow Host

A shadow host is a node with a shadow root in the Document Object Model (DOM). Typically, scoped shadow subtrees are contained within conventional element nodes on the parent page. With the exception of the shadow root, all child nodes that reside beneath a shadow host remain available.

Roots of the spectrum

Shadow roots are components of the shadow host. Shadow roots are the nodes that serve as the root of a shadow DOM branch. DOM queries do not return shadow root child nodes, even if the query selector matches the child node. The node where a shadow root is constructed becomes a shadow host when it is built on a parent page node.

Establishing a shadow root system

The process of creating a shadow root is straightforward. After selecting a shadow host, a shadow root is created.

Enhancing the Human Factor in Test Automation

Selector-based test automation is incompatible with contemporary software development practices. That is why we evaluated thousands of user interfaces to replicate the actions of a human tester.

Askui James offers UI automation for any present or future technology — complete with plain-English test descriptions.

Anything can be automated

By replicating real-world interactions, ASKUI James enables the automation of all possible UI commands. Drag-and-drop, swipe instructions, and even color verifications are now supported.

Simulate human behavior

Our automation does not attempt to access underlying code selectors or the Document Object Model (DOM). It mimics human-like mouse movements and element clicks.

There will be no more selectors.

We detect UI elements exclusively based on visual attributes using contemporary Deep Learning technology. Screenshots suffice as input for us.

Compatible with all technologies

We offer automation across all UI technologies –.NET, Web, Native Mobile, and anything in between by simply automating visual attributes.

Conclusion

I’m sure you’ll agree that Shadow DOM is an incredible amount of power. We have proper encapsulation for the first time in history without the additional baggage associated with frames or other legacy approaches. While Shadow DOM is a difficult beast, it is one that the web platform should embrace.
