 You might face [build timeout issue on Travis](https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received) if runner takes more than 10 minutes to run tests. 
 
 There are 2 possible ways to solve this problem: 
-  1. Run a script which does `console.log` every 1-2 minutes. This will output to console and hence avoid Travis buildtimeout
-  2. Use `travis_wait` function provided by Travis-CI. prefix `browserstack-runner` by `travis-wait`

-We would recommend using `travis_wait` function. It also allows you to configure wait time (ex: `travis_wait 20 browserstack-runner` this will extend wait time to 20 minutes). Read more about `travis_wait` [here](https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received)
