Karma not running tests. Executed 0 of 0 ERROR - karma-jasmine

Question

I am trying to test in karma, yet every time I run Karma I get the same error:
$ karma start karma.conf.js --single-run

Wound up just running ng test from C:\Users\king\Desktop\_REPOS\inventivangular which generated its own karma.conf.js and everything worked.
If you are using auto-generated tests you may need to:
import { HttpClientTestingModule } from '#angular/common/http/testing'
and
imports: [HttpClientTestingModule]
