Tests will execute after a build is executed via Karma, and it will automatically watch your files for changes. You can run tests a single time via --watch=false or --single-run.

You can run tests with coverage via --code-coverage. The coverage report will be in the coverage/ directory.

--colors enable or disable colors in the output (reporters and logs)

--log-level level of logging

--port port where the web server will be listening
