Travis is Failing without showing a reason - mysql

Question

I am trying to build my project through travis-ci, but unknown error is happening when travis tries to test the project through mocha. i know the issue is not with mysql since the connection is there and scripts are working.
I am testing using
- ts-node/register
- Mocha
- Chai
- Chai-http
- mySQL (using pool)
The test is working fine locally, but on travis it is failing. i am thinking that it might be something with ts-node/register, in travis.
1 - i have tried remove the test completely and the build was fixed. but when i try to test it fails miserably.
