+### Code Coverage
+For code coverage reports integration, I have shown example using Codecov and Coveralls as both are pretty popular and easy to integrate with the travis.
+
+* Codecov -  Just add [this line](https://github.com/GouravRusiya30/SpringBootRestAPI/blob/master/.travis.yml#L5) in the [.travis.yml](https://github.com/GouravRusiya30/SpringBootRestAPI/blob/master/.travis.yml) which will send the jacoco report to the codecov console
+
+* Coveralls - Need to add [coveralls plugin](https://github.com/GouravRusiya30/SpringBootRestAPI/blob/coverall-integration/build.gradle#L3) and [jacoco report path](https://github.com/GouravRusiya30/SpringBootRestAPI/blob/97df783623e5c35696451c580cc7895d17c0743a/build.gradle#L52) in the build.gradle file. Also need change in [.travis.yml](https://github.com/GouravRusiya30/SpringBootRestAPI/blob/97df783623e5c35696451c580cc7895d17c0743a/build.gradle#L52) instead of codecov to use coveralls
