Provides the ability to specify a different element query mechanism other than querySelector and querySelectorAll. An example of the usage with Georgegriff/query-selector-shadow-dom looks like this: import { querySelectorAllDeep, querySelectorDeep } from 'query-selector-shadow-dom'; configure({ queryElement: querySelectorDeep, queryAllElements: querySelectorAllDeep, }) After this line, a query will also drill into the shadow dom of elements on the page Why: In our project, we are using a design system build with web components (via stenciljs), and different projects in different frameworks (lit, react, vue) want to use this library. The corresponding pr can be found here: testing-library/dom-testing-library#1054
