how to configure travis to allow me to use nslookup

Question

I wrote my own open source library code.

https://github.com/simkimsia/UtilityLib/

I have a function which attempts to get IP address by host.

https://github.com/simkimsia/UtilityLib/blob/master/Lib/HttpLib.php#L34

I wrote a test case for this.

https://github.com/simkimsia/UtilityLib/blob/master/Test/Case/Lib/HttpLibTest.php#L45

It passed in my localhost, but failed in Travis CI.

See https://travis-ci.org/simkimsia/UtilityLib/jobs/8874800

Basically it says nslookup not found.

How should I configure travis to allow me to use nslookup?

nslookup is not installed by default on the VMs. You can install it by adding this to your .travis.yml:

before_install:
  - sudo apt-get -qq update
  - sudo apt-get -qq install dnsutils
