Testing meteor js/mocha with wercker pipeline hangs - meteor

Question

I've got an app I can test locally without issue using
meteor test-packages --velocity
// result
[[[[[ Tests ]]]]]
=> Started proxy.
=> Started MongoDB.
=> Started your app.
=> App running at: http://localhost:3000/
PASSED mocha : sanjo:jasmine on server => works
TESTS RAN SUCCESSFULLY
Each package.js in the app I'm testing has the following :
Package.onTest(function(api) {
api.use(['mike:mocha-package#0.5.8','velocity:core#0.9.3]);
api.addFiles('tests/server/example.js', 'server');
});
Now I'm trying to do the same via the Wercker pipeline using the following wercker.yml :
build :
box: ubuntu
steps :
# have to install meteor to run the tests
- script :
name : meteor install
code : |
sudo apt-get update -y
sudo apt-get -y install curl wget
cd /tmp
wget https://phantomjs.googlecode.com/files/phantomjs-1.9.1-linux-x86_64.tar.bz2
tar xfj phantomjs-1.9.1-linux-x86_64.tar.bz2
sudo cp /tmp/phantomjs-1.9.1-linux-x86_64/bin/phantomjs /usr/local/bin
curl https://install.meteor.com | /bin/sh
# run tests using meteor test cli
- script :
name : meteor test
code : |
meteor test-packages --velocity --settings config/settings.json
The meteor install step works fine but then the pipeline just hangs here :
[[[[[ Tests ]]]]]
=> Started proxy.
=> Started MongoDB.
=> Started your app.
=> App running at: http://localhost:3000/
Any ideas ? Am I not installing phantomjs correctly ?
UPDATE :
after discovering the DEBUG=1 flags... i run
DEBUG=1 VELOCITY_DEBUG=1 meteor test-packages --velocity
on both dev and in wercker.yml

Answer 1

Try to add --once flag into you testing command.

Answer 2

I haven't quite figured out the implementation with Mocha, but I have found the implementation using 'TinyTest'. Since I thought this would be useful for other users, I've put together a minimal example of Meteor with a few CI providers (CircleCI, Travis, and Wercker).
Of course, you'll need NodeJS installed. This varies by CI provider, but in the case of Travis CI, you'll want a configuration like this :
sudo: required
language: node_js
node_js:
- "0.10"
- "0.12"
- "4.0"
Then, assuming you're building a Meteor package, you'll effectively do the following steps in any CI environment :
# Install Meteor
meteor || curl https://install.meteor.com | /bin/sh
# Install spacejam
npm install -g spacejam
# Execute your tests
spacejam test-packages ./
