Auto Authorize SSH Auth Requests on Travis CI

Question

I'm doing something in my build to get this output in my travis tests. It hangs since my test cannot accept or decline, and the test fails:

The authenticity of host 'heroku.com (50.19.85.154)' can't be established.
RSA key fingerprint is 8b:48:5e:67:0e:c9:16:47:32:f2:87:0c:1blah.
Are you sure you want to continue connecting (yes/no)? 

I had a similar problem with github.com but I changed to read only urls. Instead of dealing with this problem for every x.com that hosts a git repo, is there a way to have travis just auto authorize any auth request via ssh that is made? I can do this locally via something like this: http://debuggable.com/posts/disable-strict-host-checking-for-git-clone:49896ff3-0ac0-4263-9703-1eae4834cda3 is it possible to set something like that up on Travis?

Ok, think i figured it out. One option is to add those lines to your ~/.ssh/config in a before_script like this:

before_script:
  - echo -e "Host heroku.com\n\tStrictHostKeyChecking no\n" >> ~/.ssh/config
  - echo -e "Host github.com\n\tStrictHostKeyChecking no\n" >> ~/.ssh/config

Seems to do the trick.
