* Speed up testing * make notification run in the background, this recudes the test_readme time from 18s to 0.10s * reduce time for zone reload * TestServeDNSConcurrent remove entirely. This took a whopping 58s for ... ? A few minutes staring didn't reveal wth it is actually testing. Making values smaller revealed race conditions in the tests. Remove entirely. * Move many interval values to variables so we can reset them to short values for the tests. * test_large_axfr: make the zone smaller. The number used 64K has no rational, make it 64/10 to speed up. * TestProxyThreeWay: use client with shorter timeout A few random tidbits in other tests. Total time saved: 177s (almost 3m) - which makes it worthwhile again to run the test locally: this branch: ~~~ ok github.com/coredns/coredns/test 10.437s cd plugin; time go t ./... 5,51s user 7,51s system 11,15s elapsed 744%CPU ( ~~~ master: ~~~ ok github.com/coredns/coredns/test 35.252s cd plugin; time go t ./... 157,64s user 15,39s system 50,05s elapsed 345%CPU () ~~~ tests/ -25s plugins/ -40s This brings the total on 20s, and another 10s can be saved by fixing dnstapio. Moving this to 5s would be even better, but 10s is also nice. Signed-off-by: Miek Gieben <miek@miek.nl> * Also 0.01 Signed-off-by: Miek Gieben <miek@miek.nl>
