This page explains how to develop the experimental Node.js-based Orion server. See Orion/Node/Getting started for an introduction.

Running the tests

Our unit tests are written against the Mocha test framework.

From the org.eclipse.orion.client/modules/orionode directory, just run the command:

 npm test

This will invoke Mocha and produce console output showing which tests passed and failed. Orion-Node-Developing-testrun.png


If you didn't install the Mocha package globally (or if you want to pass custom arguments to Mocha), run this instead:

 ./node_modules/mocha/bin/mocha [debug] [options] [files]

To make this easier, you can install Mocha as a global npm package (npm install mocha -g), and then invoke it as simply mocha from a command shell.

Writing more tests

When you're prototyping a new feature, writing unit tests for it is always a good idea. Here's how to write a test:

  1. Create a new file my_tests.js in the org.eclipse.orion.client/modules/orionode/test/ directory.
  2. Write your tests in the file. Here are two resources to help you get started:
  3. Run the tests (see instructions above).
    • You don't have to register your new tests with the framework; it will discover anything in the test/ directory automatically.

Helper data or classes should go in test/support/.

Minification for speed and profit*

The client code can be minified. This greatly reduces load times when accessing the server. See Orion/Releng Builds for instructions.
