Try zombie, and with cucumberjs sometimes.
npm install
npm install -g mocha
npm install -g cucumber
In one shell:
node app/app.js
to start a server.
zombiejs tests are inside test
dir.
In another shell
mocha
It will run all the zombiejs tests only.
cucumberjs tests are inside features
dir.
Run in shell:
cucumber.js
It will run the cucumber tests only.
