dns.promises test coverage is poor
Ref: https://github.com/nodejs/node/issues/20435#issuecomment-403959141
Experimental dns/promises
API is present in the current master
without proper test coverage.
According to the coverage report, the following functions are not tested at all:
onlookup
onlookupall
onlookupservice
createLookupServicePromise
While inspecting the experimental fs.promises
, there were also some implementation bugs found that could have been caught by code coverage, see e.g. #20407. The dns.promises
is much smaller in lines of code, but it is still possible that it contains bugs that could be noticed by extending coverage.
