undefined is not a constructor (evaluating 'test.isPending()') at undefined

I can't find any follow up discussion on this issue and I'm having problem with it so I thought I open one here.

I've tried both mocha v2.5.3 and v3.2.0. These are the typical errors I'm getting

Warning: TypeError: undefined is not a constructor (evaluating 'test.isPending()')
    at undefined (phantomjs://code/bridge.js:47)

Using v1.0.2 (prior to adding the test.isPending() line) with the latest version of mocha v3.2.0 works perfectly fine though (v2.5.3 as well).
