How to skip unit test

[sid-ihycq]

i upgrade to ionic4 recently, but i found there is no options in the doc pointed out how to close unit test. i don't need it, it's just way too much trouble.
angular project can use "ng new my-app --skipTests=true", anyone can tell me how to skip the unit test like this?

Gonna lump this in with this issue: #3499
