While implementing tests for new option
tries
on Resolver I noticed that it took at least 900ms more than it should when the timeout was > 1000.So a 1000ms timeout would actually take ~1900ms to trigger.
The reason is that the wrapper would register a timer in which callback
interval
andtimeout
was 1000ms in this case, which caused the callback to fire only after thistimeout
, leading to one moreinterval
of waiting to be fired again.In addition, this also adds missing tests for the option
tries
