Login to https://travis-ci.org with Github and navigate to https://travis-ci.org/profile

Enable travis support for your project listed there.

You can configure tests with two environment variables:

• WORKING_DIR -- working directory to run meteor from
• PACKAGES -- list of package names or directories to test, separated by ;, by default ./; specfiy empty string to test all packages
• TEST_COMMAND -- you can specify a custom command to run, instead of default meteor, it gets all the arguments meteor would; this is useful if you want to do some more pre- or post-processing
• METEOR_RELEASE -- you can specify the meteor release to run the tests with.

If you would like to specify more arguments (such as --settings), create a simple shell script and pass the path to TEST_COMMAND.

Create the following travis.sh (name not important):

#!/bin/sh
meteor "$@" --settings test/settings.travis.json

Add the following environment variable to your .travis.yml:

env: TEST_COMMAND=./travis.sh

Be sure to set the executable flag on your new script:

$ chmod +x travis.sh
