Description

The unittest takes very long time to run (about 40 minutes on a macbook). By overriding the test.runners, it could speed up the test, especially on powerful servers. Currently, it's set to 1 by default. I would like to propose to set the test.runners by the number of CPUs dynamically. For example, runners = num_cores / 4. What do you guys think?
