Heads Up! You're viewing the docs for v5.1, an old version of Karma. v6.4 is the newest.

Jenkins CI

Jenkins CI is one of the most popular continuous integration servers in the market today. At some point while developing your AngularJS project (hopefully early on), you might want to have automated tests run off your code versioning system. Jenkins will help you with this task. This tutorial assumes you have Jenkins already setup and running on your CI environment.

Install Prerequisites #

You need the following tools installed on your Jenkins CI server:

  • Node
  • Karma

The following Jenkins plugin is optional, but the next guidelines are based on it:

  • EnvInject - it makes things easier under certain linux distributions and user permissions.

Configure Karma #

Make the following additions and changes to your karma.conf.js file as needed:

singleRun: true,
reporters: ['dots', 'junit'],
junitReporter: {
  outputFile: 'test-results.xml'

Please note the test-results.xml files will be written to subdirectories named after the browsers the tests were run in inside the present working directory (and you will need to tell Jenkins where to find them).

Create a new Jenkins Job #

In Jenkins, start a new job for Angular/Karma with the basic settings (Name, description, parameters, source code repo to pull from, etc.)

Configure the Build Environment #

First go to the job page and click on configure. Then in the Build Environment sub-section, check the “Inject environment variables to the build process' checkbox. A few textboxes will appear and in the “Properties Content” box set the following:

$ PATH=/sbin:/usr/sbin:/bin:/usr/bin:/usr/local/bin
$ PHANTOMJS_BIN=/usr/local/bin/phantomjs #or wherever PhantomJS happens to be installed

Further down the page, in the Post-build Actions sub-section add a Publish JUnit test result report from the Post-build action drop down menu. When the textbox labeled Test report XMLs appears, enter the path to where the test-results.xml files are relative to the root of your Jenkins job workspace (you can use wildcards for this, so **/test-results.xml will find the file even if it was stored inside a browser-specific subdirectory).
