Chapter 68: angular-cli test coverage test coverage is defined as a technique which determines whether our test cases are actually covering the application code and how much code is exercised when we run those test cases. Angular CLI has built in code coverage feature with just a simple command ng test --cc Section 68.1: A simple angular-cli command base test coverage If you want to see overall test coverage statistics than of course in Angular CLI you can just type below command, and see the bottom of your command prompt window for results. ng test --cc // or --code-coverage Section 68.2: Detailed individual component base graphical test coverage reporting if you want to see component's individual coverage of tests follow these steps. 1. 2. 3. npm install --save-dev karma-teamcity-reporter Add `require('karma-teamcity-reporter')` to list of plugins in karma.conf.js ng test --code-coverage --reporters=teamcity,coverage-istanbul note that list of reporters is comma-separated, as we have added a new reporter, teamcity. after running this command you can see the folder coverage in your dir and open index.html for a graphical view of test coverage.

You can also set the coverage threshold that you want to achieve, in karma.conf.js, like this. coverageIstanbulReporter: { reports: ['html', 'lcovonly'], fixWebpackSourcePaths: true, thresholds: { statements: 90, lines: 90, branches: 90, functions: 90 } }, GoalKicker.com – Angular 2 Notes for Professionals 220
