<code>data</code> Attributes for Testing
Read OriginalThe article discusses a testing strategy for web components where internal state or attributes (like href, variant, size) are lifted from the shadow DOM and exposed as stable data-* attributes on the component's root element. This makes tests more declarative, resilient to internal implementation changes (e.g., switching CSS frameworks or dropping web components), and avoids the fragility of directly querying the shadow DOM.
