Queries the subject element for the first descendant element with the given data-test-id
attribute and forwards it to another assertion.
If the data-test-id is not found it fails.
var element = createElement(`<section><h1>Numbers</h1><hr><ol data-test-id="numbers"><li >One</li><li>Two</li><li>Three</li></ol></section>`);expect(element, 'queried for test id', 'numbers', 'to satisfy', {children: expect.it('to have length', 3),});
If no matching element can be found you get the following error:
expect(element, 'queried for test id', 'emojies', 'to satisfy', {children: expect.it('to have length', 666),});
expected<section><h1>Numbers</h1><hr><ol data-test-id="numbers"><li>...</li><li>...</li><li>...</li></ol></section>queried for test id 'emojies' to satisfy { children:}expect.it('to have length', 666)expected DOMElement queried for first [data-test-id="emojies"]The selector [data-test-id="emojies"] yielded no results
In case the next assertion fails you will get an error looking like this:
expect(element, 'queried for test id', 'numbers', 'to have no children');
