Test don't run due to --single-run option

Current behavior

Attempt to run tests but get:

PS C:\Users\wayne\Projects\VidLessons> npm test

> [email protected] test C:\Users\wayne\Projects\VidLessons
> ng test --single-run --code-coverage

Unknown option: '--singleRun'

Expected behavior

Tests would run, once

Minimal reproduction of the problem with instructions

1. Generate default app (named 'VidLessons' in my case)
2. cd into dir
3. npm test

Note: ng test runs; the problem is just the single-run flag that's a problem, it's not among the options listed with ng test --help

What is the motivation / use case for changing the behavior?

Should be able to test under Angular 6

Environment
