Revision 89ba9443f1d80b2bea3a33477b1ac53585fbb16d authored by jimevans on 16 March 2018, 14:46:32 UTC, committed by Andreas Tolfsen on 16 March 2018, 14:46:32 UTC
When the context element is `document.documentElement`, and an attempt is made to find elements from that context element using an XPath of `..`, a snapshot is returned containing the `document` object. While this is apparently the correct behavior for XPath, the WebDriver spec says that if the object in the snapshot is not an element, we should return an error with error code "invalid selector." The test_parent_htmldocument test in both find_element_from_element.py and find_elements_from_element.py expect a success in this case. This commit changes the tests to correctly expect an error from the driver.

<h1>Description</h1>
<p>This test validates that the performance.measure() method is working properly when navigation timing
attributes are used in place of mark names. This test creates the following measures to test this method:
<ul>
<li>"measure_nav_start_no_end": created using a measure() call with a navigation timing attribute
provided as the startMark and nothing provided as the endMark</li>
<li>"measure_nav_start_mark_end": created using a measure() call with a navigation timing attribute
provided as the startMark and a mark name provided as the endMark</li>
<li>"measure_mark_start_nav_end": created using a measure() call with a mark name provided as the
startMark and a navigation timing attribute provided as the endMark</li>
<li>"measure_nav_start_nav_end":created using a measure() call with a navigation timing attribute
provided as both the startMark and endMark</li>
</ul>
After creating each measure, the existence of these measures is validated by calling
performance.getEntriesByName() with each measure name
