+#### Code Coverage Reports
 
+Unit test coverage reports are automatically generated using the [karma-coverage][karma-coverage] plugin.
+This plugin creates an HTML code coverage report with [Istanbul][istanbul] to give you Statement, Branch,
+Function, and Line coverage statistics for your tests.
+
+* the configuration is found at 'karma.conf.js'
+* the reports are available under 'build/reports/coverage/'
