Versions.

node --version v6.10.1 npm --version 3.10.10 macOS (Sierra)

Repro steps.

1. npm run test (which runs ng test --environment=local) This works fine (tests run successfully, using the specified environment).
2. change a .spec test file This fails - it tries to re-run tests due to the change, but this time the environment is NOT used, instead the defaults environment.ts is used (which in our case leads to an error because it does not exist. Even if it did exist, it still is a bug as the proper environment is not being used).

The log given by the failure.

Desired functionality.

The environment.local.ts specified by the --environment flag is used ALL the time, not just on the first run. Which thus leads to a successful test watcher that will auto re-run tests on changes without breaking, as it does now.

Mention any other details that might be useful.

+1 This also affects the ‘serve’ command: ng serve --env=local works for the first time but on any file change ‘watch’ re-builds using the default environment.ts
