I'm trying to test my chrome extension with Jasmine but I'm having trouble getting calls.length and callCount to behave as expected. Both cases return undefined.

I've included a sample of the code and the spec. Here's the rest of the code if it helps: https://github.com/DruRly/kamikaze/tree/closeIdleTab

How to reproduce:

• git clone https://github.com/DruRly/kamikaze/tree/closeIdleTab


• cd kamikaze


• open SpecRunner.html

spec/kamikazeSpec.js

describe(kamikaze, function() {

  describe(closeIdleTabs, function(){

    it(calls closeIdleTab for each tab received, function(){

      spyOn(kamikaze, 'closeIdleTab');



      kamikaze.closeIdleTabs([1,2,3]);

      expect(kamikaze.closeIdleTab.calls.length).toBe(3);

    })

  })

})

src/kamikaze.js

kamikaze = {

  ...



  closeIdleTabs: function(tabs){

    tabs.forEach(function(tab){

      test.closeIdleTab(tab);

    })

  },



  closeIdleTab: function(tab){

    if(tabTimeStamps[tab.id]){

      var secondsSinceUpdated = getSecondsSinceUpdated(tab.id)

      if(secondsSinceUpdated > (minutesUntilIdle * 60)){

        chrome.tabs.remove(tab.id)

      }

    }

  },



  ...

}
