Updating the version of Jasmine used in karma-jasmine

Question

Questions

• How can I update the version of Jasmine used when running Jasmine via Karma using the karma-jasmine plugin?
• Will Jasmine only get updated whenever the karma-jasmine plugin integrates a newer version of Jasmine, or can I point the karma-jasmine plugin to a newer version of Jasmine?
• What version of Jasmine is installed by karma-jasmine?

Background

I've installed Karma and karma-jasmine using Yeoman as follows:

$ npm install -g generator-angular
$ mkdir myapp && cd $_
$ yo angular

Given that myapp/bower.json didn't list Jasmine as one of the Bower installed front-end packages but myapp/karma.conf.js listed Jasmine as the default testing framework, I was surprised the command grunt test worked. (The Gruntfile.js, bower.json, and karma.conf.js files were all created as part of the yo angular scaffolding process.)

Upon closer inspection of the myapp/node_modules packages, I realized that karma-jasmine doesn't point to a separate installation of Jasmine. The karma-jasmine plugin actually installs Jasmine:

▼ myapp/
  ▼ karma_jasmine/
    ▼ lib/
        adapter.js
        index.js
        jasmine.js

Given that karma-jasmine says it is an "adapter for the Jasmine testing framework," I was a little surprised that karma-jasmine didn't require us to install Jasmine separately.

Package Versions

Here are the various package versions used:

• Karma: "~0.10.8" per myapp/package.json contents
• karma-jasmine: "~0.1.4" per myapp/package.json contents
• Yeoman: "1.0.6" per npm list -g | grep yo command results
• Jasmine: Unknown but based on a few diffs, I'm almost wondering if karma-jasmine includes a customized version of Jasmine to work with Karma.

Answer 1

You can know the jasmine version you are using by running the following Spec:

describe('Test to print out jasmine version', function() {
  it('prints jasmine version', function() {
    console.log('jasmine-version:');
    console.log(jasmine.version || (jasmine.getEnv().versionString && jasmine.getEnv().versionString()));
  });
});

and then checking the karma output in your console or browser. It should be something like:

LOG: 'jasmine-version:'
LOG: '2.3.4'

The jasmine library is included in the jasmine-runner plugin as you've already found out. You can find the exact place where this file is loaded in the source code of the plugin: https://github.com/karma-runner/karma-jasmine/blob/master/lib/index.js (line 7)

You can try to modify the plugin so that an upgrade is possible and send a pull request to karma (see http://karma-runner.github.io/0.10/dev/contributing.html)

It a better option to stick to the jasmine version in karma-jasmine and update the whole package. You can use the following command to get the version of all the installed packages:

  npm ls

To get the version of the installed global packages:

  npm ls -g

To view the latest version available on CDN, use:

  npm view karma-jasmine version

Before updating, you can view all versions at the CDN using:

  npm view karma-jasmine versions

To install a specific version:

  npm install karma-jasmine@~0.2.2 

(0.2.2 is the latest available).
