Dispatch:mocha-phantomjs - TypeError: Cannot call method 'push' of undefined on Windows



I’m trying to run some mocha tests on the command line with the dispatch:mocha-phantomjs package. It’s not working however with the following errors:

  • When I run meteor test --once --driver-package dispatch:mocha-phantomjs no tests are run and meteor exits after starting:
PS E:\meteor-projects\simple-todos-react> meteor test --once --driver-package dispatch:mocha-phantomjs
[[[[[ Tests ]]]]]

=> Started proxy.
=> Started MongoDB.
=> Started your app.

=> App running at: http://localhost:3000/
   Type Control-C twice to stop.

PS E:\meteor-projects\simple-todos-react>
  • If I try to keep it running without the --once flag I get the following error:

Not sure why it’s failing. I’m just following the Meteor guide on testing. I did find out that the other driver practicalmeteor:mocha has conflicts with dispatch:mocha-phantomjs when they are both installed so I removed the former but no luck it seems :frowning:. BTW I’m on windows if that makes a difference.

Any ideas? Cheers in advance.

ERROR Tutorial tests section: practicalmeteor:mocha. TypeError: Cannot call method 'push' of undefined

I’ve just tried this on a linux box and it actually worked. My main machine is windows so I imagine this is the problem sadly. Is there a way to perhaps get more detailed logging?

In the meantime I have raised a bug against the package. Will update it with this info.


I have it working on my boilerplate you want to see if it occurs there? Use the angular branch since it has more elaborate tests. Part of my build is to remove the practicalmeteor:mocha package and add dispatch:mocha-phantomjs until their integration issues get resolved (or when @Sanjo fixes https://github.com/xolvio/meteor-jasmine/issues/335 meteor-jasmine to work in CI environments)


Thanks @trajano. So there is where we get to have fun :stuck_out_tongue:

It does indeed work (mostly) when practicalmeteor:mocha is installed suggesting there’s a further dependency. However when this package is present there’s a conflict issue causing an error during runtime:

This issue was raised here - https://github.com/DispatchMe/meteor-mocha-phantomjs/issues/7

When I removed the practicalmeteor:mocha from your boilerplate the same original issue occurs on my windows machine where nothing is posted and nothing is run.

Fun one!


Oh ya I remember that issue. Don’t run dispatch:phantomjs on Windows :slight_smile: I I openned https://github.com/DispatchMe/meteor-phantomjs-tests/issues/1 regarding that myself. I did put a PR https://github.com/DispatchMe/meteor-phantomjs-tests/pull/2 regarding the issue and waiting on @aldeed to review If you want to do it manually go to your AppData\local\.meteor\... and change the file specified by the issue. I don’t have it at the moment since I cleared off my meteor installation and I don’t use CI locally at the moment.


Ahh nice one. So it’s an issue with the phantomjs package! Obvious now I look at it again.

Just to confirm is it this file? AppData\Local\.meteor\packages\dispatch_phantomjs-tests\0.0.4\os.windows.x86_32\server.js?


I guess there are two issues here. The one above due to Windows and the other that the test doesn’t even run without the practicalmeteor:mocha package installed (again on Windows)

However on linux it runs fine without the practicalmeteor:mocha package… So confusing :confused:


Practical meteor mocha will have issues with phantom js dispatch regardless whether it is windows or Linux. So make sure only one is installed.

Also there is a PR regarding not using practical meteor for the chai and sinon for the guide I have created but I have not committed any time to fix the todo sample app. Though my boilerplate already does not use any practical meteor specific


Has been merged woo hoo, eliminates the platform problem, unfortunately when I did my test I got another error that is resolved by the following PR


Haha. Yeah I saw the merge today. Will now wait on the other PR :stuck_out_tongue:

With the new version though I still don’t seem to be having much luck. It still doesn’t run any tests with only dispatch driver installed:

PS E:\app> meteor add dispatch:mocha-phantomjs

Changes to your project package version selections:

dispatch:mocha-core         added, version 0.0.1
dispatch:mocha-phantomjs    added, version 0.1.1

practicalmeteor:mocha-core  added, version 0.1.4

PS E:\app> meteor test --once --driver-package dispatch:mocha-phantomjs

PS E:\app>


Actually I just got it working by uninstalling both drivers and specifically installing practicalmeteor:mocha and then dispatch:mocha-phantomjs in that specific order.

Currently dispatch tests will run but practical tests won’t. The page is just empty and the tests get ignored. I think this is already known though.


Odd I am using practicalmeteor:mocha on Windows with no issues (though the dispatch:mocha-phantomjs must not be installed) You can try it it from https://github.com/trajano/meteor-boilerplate just run meteor npm test and access http://localhost:3100/ for a more elaborate test use the angular branch
