/**

|
* Allows you to find a DOM element based on the value of its `data-testid` attribute.
|
|
* This attribute can be used to decouple identifying dom elements for testing from
|
|
* styling (which is typically done via class selectors) or other ids which serve
|
|
* different purposes.
|
|
* See also https://kentcdodds.com/blog/making-your-ui-tests-resilient-to-change
|
|
* Inspired by https://testing-library.com/docs/queries/bytestid/
|
|
* @param {HTMLElement} container - A parent element of the DOM element to find
|
|
* @param {string} testId - The value of the `data-testid` attribute of the component to find.
|
|
* @returns The found element or null if there was no such element
