There is a configuration property explained on Testem readme to enable remote debugging phamtojs:
If you want to debug tests in PhantomJS, include the phantomjs_debug_port option in your testem configuration, referencing an available port number. Once testem has started PhantomJS, navigate (with a traditional browser) to http://localhost: and attach to one of PhantomJS's browser tabs (probably the second one in the list). debugger statements will now break in the debugging console.
But adding it to config/spec.json doesn't seem to have effect.
