Templates should include Travis CI configuration

[imaustink]

Using Testee to launch FireFox on Travis requires special configuration to prevent errors. A default configuration should be added to the plugin, and probably the app templates.

This is the required configureation, note the dbus installation:

language: node_js
node_js:
  - "6"
addons:
  firefox: "latest-esr"
  apt:
    packages:
      - dbus-x11
before_install:
  - "export DISPLAY=:99.0"
  - "sh -e /etc/init.d/xvfb start"

For more information about this issue, see bitovi/testee#157.

I opened a PR for this, although it may need to be updated: #265

The plugin generator has a template already: https://github.com/donejs/generator-donejs/blob/33cdf07aeacd6303abdd91572466d6effeca35ce/plugin/templates/static/.travis.yml.

Shouldn't that be in the root instead of under the static folder?

[phillipskevin]

I'm not sure why the static folder exists. The way the code works, those files cannot use template replacements (like <%= name %>) like the files outside of static can. I'm not sure why it was done this way, but we definitely shouldn't have the file in two places.
