I get the following error when trying to run the tests:
Command failed: /usr/local/lib/node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs /usr/local/lib/node_modules/a11y/audits.js {"delay":1,"url":"http://bbc.co.uk","width":1024,"height":768} --ignore-ssl-errors=true --ssl-protocol=tlsv1 --local-to-remote-url-access=true
Audit failed
I got a similar error on initial install so I manually installed PhantomJS but still can't get any test to work.

Can you confirm what version of PhantomJS you have locally installed?
rickydazla commented
1.9.1.7
sjurlur commented
npm ls phantomjs
a11y@0.4.1 /usr/local/lib/node_modules/a11y
└── phantomjs@2.1.7
jatinsi commented
Try uninstalling phantomjs and a11y and reinstalling only a11y.
npm uninstall a11y --global
npm uninstall phantomjs --globalnpm install --global a11y
I fixed the same issue on my machine using the above step.

I’m getting this same error when trying to run a11y on certain websites, but not all. I’ve yet to find a definitive factor that predictably determines whether a11ying a site will result in this error or not. I do know that the sites where it does fail, it does so consistently.
http://bbc.co.uk, as reported by @maureeno20, gets the error. So does http://asmallbatch.co. Both of those locations have redirects, but so does http://mrkp.co and that one loads fine.
Reinstalling a11y globally does not seem to have an effect, in my case. The only version of phantomjs I have installed (globally, anyway) is the one installed as a dependency of a11y:
$ npm ls --global phantomjs
/Users/agarzola/.nvm/versions/node/v4.2.4/lib
└─┬ a11y@0.4.1
└── phantomjs@2.1.7
jonnyi commented
@agarzola Seeing the exact same issues even following the reinstallation step for a11y and phantomjs.

When I ran the command that a11y generates, I got a bit more info on what was going wrong:
/Users/bennyp/.config/yarn/global/node_modules/phantomjs-prebuilt/lib/phantom/bin/phantomjs /Users/bennyp/.config/yarn/global/node_modules/a11y/audits.js {"delay":1,"url":"http://mrkp.co","width":1024,"height":768} --ignore-ssl-errors=true --ssl-protocol=tlsv1 --local-to-remote-url-access=true

So here's some more verbose debugging info:

Hey! Look at that! that JSON string is being interpreted as an array of arguments. Let's wrap it in a single quote:

Now it looks like a dependency problem. yarn global add phantomjs-polyfill; and yarn global add accessibility-developer-tools doesn't seem to help much.
( long shot but this might also be related to ariya/phantomjs#12697 and https://github.com/addyosmani/a11y/blob/master/audits.js#L104-L109 )
