Description

This test validates that the performance.measure() method is working properly. This test creates the following measures to test this method:

"measure_no_start_no_end": created using a measure() call without a startMark or endMark provided
"measure_start_no_end": created using a measure() call with only the startMark provided
"measure_start_end": created using a measure() call with both a startMark or endMark provided
"measure_no_start_no_end": duplicate of the first measure, used to confirm names can be re-used
After creating each measure, the existence of these measures is validated by calling performance.getEntriesByName() (both with and without the entryType parameter provided), performance.getEntriesByType(), and performance.getEntries()

PASS window.performance.getEntriesByName("measure_no_start_no_end")[1].duration is approximately correct (up to 20ms difference allowed) 
PASS window.performance.getEntriesByName("measure_no_start_no_end", "measure")[0] returns an object containing the "measure_no_start_no_end" measure in the correct order, and its value matches the "measure_no_start_no_end" measure returned by window.performance.getEntriesByName("measure_no_start_no_end") 
PASS window.performance.getEntriesByName("measure_start_no_end", "measure")[0] returns an object containing the "measure_start_no_end" measure in the correct order, and its value matches the "measure_start_no_end" measure returned by window.performance.getEntriesByName("measure_start_no_end") 
PASS window.performance.getEntriesByName("measure_start_end", "measure")[0] returns an object containing the "measure_start_end" measure in the correct order, and its value matches the "measure_start_end" measure returned by window.performance.getEntriesByName("measure_start_end") 
PASS window.performance.getEntriesByName("measure_no_start_no_end", "measure")[1] returns an object containing the "measure_no_start_no_end" measure in the correct order, and its value matches the "measure_no_start_no_end" measure returned by window.performance.getEntriesByName("measure_no_start_no_end")
