Repro steps.

Later integration of Karma test into agular-cli environment and forgotten test-key-value in .angular-cli.json leads to an very hard to find error. ng test outputs the error:

Desired functionality.

An error which shows what is really missing. so====> ... "polyfills": "polyfills.ts", ----> "test": "test.ts", <----- "tsconfig": "../tsconfig.json", ...

Mention any other details that might be useful.
