Mocha Lazy BDD

Example Spec

var expect = require('chai').expect;

describe('mocha-lazy-bdd', function() {
  
  describe('lazy', function() {
    
    lazy('value', function() {
      return 'i am lazy';
    });
    
    it('returns the specified value', function() {
      expect(this.value).to.eq('i am lazy');
    });
    
  });
  
});

See this project's specs for more examples.

Installation and Usage

mocha -u mocha-lazy-bdd

mocha-lazy-bdd's Issues

invalid interface error running with karma from gruntfile

I'm getting Uncaught Error: invalid interface "lazy-bdd" when running grunt karma after a clean installation. I'm hoping you might understand this problem better than me but i'll give it shot!

I've got

karma: {
    unit: {
        configFile: 'karma.config.js',
        client: {
          mocha: {
            reporter: 'html', // change Karma's debug.html to the mocha web reporter
            ui: 'lazy-bdd'
          }
       }
    }
 }

in my Gruntfile config

I've gotten it to work by just adding 'lazy-bdd' into the mocha.js file and it works but is not a sustainable solution.
