Chapter 11: Travis CI UI Logging and Debugging

1. Yes whenever you merge a pull request in GitHub, Travis CI will automatically kick off another build.
2. No it doesn't, but you will see labels for the before_install and install lifecycle events as well as some other lifecycle events.
3. You will need to use Docker to pull down an image and you can find the full list of Docker images here (https://docs.travis-ci.com/user/common-build-problems/#Troubleshooting-Locally-in-a-Docker-Image).
4. Yes, but you will need to email [e-mail] and then request whatever specific repositories you want to have debug mode enabled for. Additionally you will need to make a call to Travis API with the corresponding job id to trigger a build in debug mode.
