Running Jasmine Tests With PhantomJS

Jasmine + PhantomJS I finally got to mess around with PhantomJS and Jasmine, and couldn’t find a resource that gives clear, concise, accurate information, without language specific or build tool specific coupling, so I decided to write it myself. Fortunately, it is way simpler than I thought.


PhantomJS is a standalone, cross platform command line application which does not require any specific server environment or programming language support.

Running the Tests

In order to run our jasmine test suite on the command line, all we need is:

Once we got these, all we have to do is run the following command: phantomjs /path/to/run-jasmine.js http://localhost/js/test/unit/ It doesn’t take more than a few seconds(!) and we are provided with the test results.

This is it. Now, lets run it with our build tool.

* For the purpose of this article, lets assume PhantomJS is installed on the system, our jasmine runner is located at /path/to/run-jasmine.js and our jasmine test suite is located at http://localhost/js/test/unit/

Hooking with Build Tools

GNU Make

Adding the following target to Makefile and running make js_unit_test should do the trick:

	@phantomjs /path/to/run-jasmine.js http://localhost/js/test/unit/

Rake (Ruby Make)

Adding the following task to Rakefile and running rake js_unit_test should do the trick:

task :js_unit_test do
  exec 'phantomjs /path/to/run-jasmine.js http://localhost/js/test/unit/'

Apache Ant

Adding the following target to build.xml running ant js_unit_test should do the trick:

<target name="js_unit_test" description="Runs Javascript Unit Tests">
    <exec executable="phantomjs" failonerror="true">
       <arg line="/path/to/run-jasmine.js" />
       <arg line="http://localhost/js/test/unit/" />


Adding this to any build tool should be as simple as it gets. The script will exit with 0 code on success, and 1 on failure, which is what most build tools need to know.


Following three simple steps enables us run our unit tests on a real WebKit based browser from the command line - no programming required. This method is NOT specific to AMD test suites. The URI could have a file:// scheme rather than http://
