/**
* @public
*
* Validates if an element (or elements) matches a given selector.
*
* Useful for checking if an element (or elements) matches a selector like
* `:disabled` or `:checked`, which can be the result of either an attribute
* (`disabled="disabled"`, `disabled=true`) or a property (`disabled`).
*
* @example
* // <input type="checkbox" checked="checked">
* // <input type="checkbox" checked>
*
* const page = PageObject.create({
* areInputsChecked: is(':checked', 'input', { multiple: true })
* });
*
* assert.equal(page.areInputsChecked, true, 'Inputs are checked');
*
* @example
* // <button class="toggle-button active" disabled>Toggle something</button>
*
* const page = PageObject.create({
* isToggleButtonActive: is('.active:disabled', '.toggle-button')
* });
*
* assert.equal(page.isToggleButtonActive, true, 'Button is active');
*
* @param {string} testSelector - CSS selector to test
* @param {string} targetSelector - CSS selector of the element to check
* @param {Object} options - Additional options
* @param {string} options.scope - Nests provided scope within parent's scope
* @param {boolean} options.resetScope - Override parent's scope
* @param {number} options.at - Reduce the set of matched elements to the one at the specified index
* @param {boolean} options.multiple - If set, the function will return an array of values
* @param {String} options.testContainer - Context where to search elements in the DOM
* @return {Descriptor}
*
* @throws Will throw an error if no element matches selector
* @throws Will throw an error if multiple elements are matched by selector and multiple option is not set
