4. Make sure you get the latest version. On Ubuntu, use the PPA rather than the default package.
Installing node
It’s time to stop pretending we’re not in the JavaScript game. We’re doing web develop‐
ment. That means we do JavaScript. That means we’re going to end up with node.js on
our computers. It’s just the way it has to be.
Follow the instructions on the
node.js download page .There are installers forWindows
and Mac, and repositories for popular Linux distros.

Once we have node, we can install phantom:
$
npm install -g phantomjs
# the -g means "system-wide". May need sudo.
Next we pull down a QUnit/PhantomJS test runner. There are several out there (I even
wrote a basic one to be able to test the QUnit listings in this book), but the best one to
get is probably the one that’s linked from the
QUnit plugins page .At the time of writing,
its repo was at
https://github.com/jonkemp/qunit-phantomjs-runner. The only file you
need is
runner.js
.
You should end up with this:
$
tree superlists/static/tests/
superlists/static/tests/
├── qunit.css
├── qunit.js
├── runner.js
└── sinon.js
0 directories, 4 files
Let’s try it out:
$
phantomjs superlists/static/tests/runner.js lists/static/tests/tests.html
Took 24ms to run 2 tests. 2 passed, 0 failed.
$
phantomjs superlists/static/tests/runner.js accounts/static/tests/tests.html
Took 29ms to run 11 tests. 11 passed, 0 failed.
Just to be sure, let’s deliberately break something:
lists/static/list.js (ch20l019).
$
(
'input'
).
on
(
'keypress'
,
function
() {
//$('.has-error').hide();
});
Sure enough:
$
phantomjs superlists/static/tests/runner.js lists/static/tests/tests.html
Test failed: undefined: errors should be hidden on keypress
Failed assertion: expected: false, but was: true
