Usage: 
  ng test <project> [options]

--code-coverage-exclude

--configuration
One or more named builder configurations as a comma-separated list as specified in the "configurations" section of angular.json. The builder uses the named configurations to run the given target. Setting this explicitly overrides the "--prod" flag. Aliases: -c
--help default:false
Shows a help message for this command in the console.
--include
Globs of files to include, relative to workspace or project root. There are 2 special cases: when a path to directory is provided, all spec files ending ".spec.@(ts|tsx)" will be included when a path to a file is provided, and a matching spec file exists it will be included instead

Karma reporters to use. Directly passed to the karma runner.

Output source maps for scripts and styles.
