We don't add the ':' at the end of the description string, one is added
automatically by the test harness.

Thanks falken

Without ':' For Fail condition it will display like

FAIL Event constructors assert_equals: Type of ExtendableEvent should be
ExtendableEvent expected "ExtendebleEvent" but got "ExtendableEvent"

Here 'Type of ExtendableEvent should be ExtendableEvent expected
"ExtendebleEvent" but got "ExtendableEvent"' looks a single line.

I put ':' to separate 'Type of ExtendableEvent should be ExtendableEvent' and 
'expected "ExtendebleEvent" but got "ExtendableEvent"'.

Is it fine to leave as a single line, or we should separate them, may be using
','?

Added this test, we cannot set explicitly cancelable to false.

need a space after the ,

+      'FetchEvent.request.url should return the value it was initialized to:');
   }, 'Event constructors');
