Add TravisCI support

[desyncr]

• Use cram https://pypi.python.org/pypi/cram
• Create .travis.yml
• Update test suite for new commands (ie, update)

I don't if it is what you need, but here is what I came with: this.

It use your version of zcram.
Travis would probably handle

pip install cram

---

I still believe we could use bats.
I did not quite look either zcram or cram, but I feel a shell-based TAP protocol would be the rigth thing for zpm.
I can provide bats test file if you want to give it a try.

First, sorry for delaying bunch of -seemenly simple- tasks for so long, I've been quite busy lately and I've been behind work for some time. I'm gonna try to catch up in this weekend.

Second, I have some experience using cram and I find it quite useful not only for testing -functional, regression- but also for documentation because of how tests are implemented.
I haven't found a similar tool written in shell. I believe it should not be a requirement though.

By the way:

• We are gonna tests against current zsh in debian (5.2 I believe), we'll need to apt-get install zsh
• We are gonna use cram, so yes, pip install cram would suffice

Something like this: https://gist.github.com/desyncr/5cb0ac4a4f1f6439fbfe867cd9e162ad
I haven't tested it though. Possible issues with:

• missing pip
• Makefile still references zcram

[fennecdjay]

It looks like

install:
  - sudo -H pip install cram

does the job.

and the Makefile can be modified with

sed -i "s/zcram/cram/" Makefile

see this.
