+ <h1>Description</h1>
+ <p>This test validates that the performance.clearMeasures() method is working properly. This test creates the
+ following measures to test this method:
+ <ul>
+ <li>"measure1"</li>
+ <li>"measure2"</li>
+ </ul>
+ After creating each measure, performance.clearMeasures() is called three times. First, it is provided with a
+ name of "measureUndefined", a non-existent measure, which shouldn't change the state of the Performance
+ Timeline. Next, it is provided with a name of "measure2", after which, this measure should no longer be
+ present in the Performance Timeline. Finally, performance.clearMeasures() is called without any name
+ provided. After this call, no measures should be present in the Performance Timeline. The state of the
+ Performance Timeline is tested with the performance.getEntriesByType() and performance.getEntries() methods.
