Here is the code in question.
define (require) ->
Backbone = require 'backbone'
require 'backbone-deferred'
class Data extends Backbone.Deferred.Model
urlRoot: 'data'
parse: (resp) ->
resp.record or resp
isValid: ->
@get 'valid'
# Newly introduced
dataUrl: ->
@get('data_url')?.replace /abc/, ''
And here is the unit test
define (require) ->
Data = require 'model/Data'
describe 'dataurl', ->
describe 'No change', ->
data = new Data id: '123', name: 'Dummy', data_url: 'https://m/a.png'
expect(data.dataUrl()).to.equal('https://m/a.png')
For some reason the test is not run by mocha.
I am using this html to drive the test

My questions are:
1) Number of test is changed at all after adding the new test. What are the possible reasons the new test is not picked up?
2) If I intentionally introduce an error in my unit test it will cause this in case of a test failure:
Warning: PhantomJS timed out, possibly due to a missing Mocha run() call. Use --force to continue.
I am sure it is related to the test but there is not enough information to diagnose the problem. How can I turn on logging or obtain additional information?
Your test case should be defined using the
itfunction instead ofdescribe(which is used to group tests)I have created this jdfiddle so you can see the difference with your original definition.
If you introduce an error in the test, if the test is not defined inside the
itfunction then it will affect the whole test run. You can check it in this other fiddle (You will notice the second test doesn't run after the error in the wrong defined test)
