Set the value of a specified DOM attribute for the given element. For all the available DOM attributes, consult the Element doc at MDN.

setAttribute() will automatically wait for the element to be present (until the specified timeout). If the element is not found, an error is thrown which will cause the test to fail. Starting with v1.2 you can suppress element not found errors by specifying the suppressNotFoundErrors option.
