Tests fail when the port 8086 is already in use

The testsuite should randomize the port and it should use a higher number to avoid collisions.

It looks like tests are run in parallel and at the same time they attempt to use the same port.

Version: 0.7.8

Hi!

I hope the v0.7.8.1 fixes this issue and the #223 too.
