This is a JavaScript implementation of Riot.

It will run in a browser or in Rhino.

Example

Tests look like this:

Riot.run(function() {
  context('basic riot functionality', function() {
    given('some simple equality tests', function() {
      asserts('a simple truth test should return true', true).isTrue();
      asserts('isNull is null', null).isNull();
    });

    given('another context', function() {
      asserts('equals should compare strings as expected', 'test string').equals('test string');
    });

    given('a context concerned with functions', function() {
      asserts('asserts() should allow functions to be compared', function() {
        return 'test string';
      }).equals('test string');
    });
  });

  given('yet another context', function() {
    asserts('equals should compare strings as expected', 'test string').equals('test string');
  });
});

There are a few aliases to make tests (and output) read more naturally:

• context: given — Given will add “Given…” to the title in the test output
• asserts: should

Assertions

• equals – for example, asserts('description').equals('value')
• matches – matches a regex
• typeOf – aliased to isTypeOf, kindOf
• isNull
• isTrue
• raises

Riot.run

Riot.run(function() { // your tests }); just adds your tests to window.onload. If there’s already an onload handler it’ll prepend it. If there’s no window it will just run the tests.

It can also be called with no parameters to run tests defined with Riot.context. This can be used to create a set of files with tests inside a Riot.context for each file

Packaging

Packaged as a RubyGem usable via XPCOMCore-RubyGems — riotjs-xpcc.
