<h1>Description</h1>
|
|
<p>This test validates that the window.performance.timing attributes change when a page is reloaded.</p>
|
|
|
|
<p>This page should be loaded with a green background frame below. The frame will be automatically reloaded
|
|
and then verified that the window.performance.timing attributes have been updated to the new reloaded navigation timings.</p>
