  Alternatively, a second argument may be passed which is an element as the
  DOM context to search within.

  @method findAll
  @param {String} CSS selector to find elements in the test DOM
  @param {Element} context to query within, query from its contained DOM
  @return {Array} An array of zero or more HTMLElement objects
