TypeError: Cannot read property 'launched' of undefined, on Travis #174
Description
I tried to get browserstack-runner work for my repository https://github.com/reeteshranjan/browse.js on Travis. Though running browserstack-runner locally on my desktop worked, things are failing on Travis. I have tried few things as explained below; however, the error is the same in all cases.
Please check https://travis-ci.org/reeteshranjan/browse.js/builds/227335152 for a build that failed. You'll see that an error was thrown after 2 browsers report to be passing.
I am interested in browserstack-runner for its JSON format report. I wrote a script as per the documentation here https://github.com/browserstack/browserstack-runner#usage-as-a-module, and a build using my own script bs-runner.js with code picked from above failed as well. Here is the link: https://travis-ci.org/reeteshranjan/browse.js/builds/227331984.
I had seen on this page https://www.browserstack.com/automate/travisci that BROWSERSTACK_LOCAL_IDENTIFIER variable is important, but did not see the code handling it well, so made my own copies of relevant files from browserstack-runner code to have enough changes to include this variable for just trying it out. Interestingly, one build passed and it is here: https://travis-ci.org/reeteshranjan/browse.js/builds/227338890. However; this was not a consistent behavior/result and this build failed: https://travis-ci.org/reeteshranjan/browse.js/builds/227340229. And another build that used my changed code and the bs-runner.js script failed as well: https://travis-ci.org/reeteshranjan/browse.js/builds/227339395.
NOTE: Please check the repository for .travis.yml.browserstack-runner file (as of now I have moved to testem for getting my builds to pass, so the .travis.yml file is not the right reference).
