| 43 | ```coffee
|
| 44 | describe 'karma tests with chai', ->
|
| 45 |
|
| 46 | it 'should expose the Chai assert method', ->
|
| 47 | assert.ok('everything', 'everything is ok');
|
| 48 |
|
| 49 | it 'should expose the Chai expect method', ->
|
| 50 | expect('foo').to.not.equal 'bar'
|
| 51 |
|
| 52 | it 'should expose the Chai should property', ->
|
| 53 | 1.should.not.equal 2
|
| 54 | should.exist 123
|
