Testing your express(a) app

Testing can be done in many ways, with or without a test framework. Here's just an easy testframework-agnostic, linux way to test your app.

package.json

Add the 'test' command in the script-section of your package.json:

"scripts":{
  "test": "for i in test/*; do [ -x $i  ] && [ ! -d $i  ] && { printf '\n<▶ '$i'\n\n' && ./$i || exit 1;  }; done;"
}

app.js

In your expressa main-file (app.js e.g.), search for app.listen(), and modify it like this:

module.exports = { 
  expressa:expressa, 
  express:express, 
  app:app, 
  server: app.listen(port, function(){
    console.log("listening on "+host)
    if( module.exports.onServerReady ) setTimeout(module.exports.onServerReady, 500 )  // fire tests if any
  })
}

test/tests/mytest.js

#!/usr/bin/env node                                                                                                                                                                                                                
var app      = require('./../../app.js')     
var expressa = app.expressa

var run = function(done){
  // do mocha stuff here etc and call done()  
}

app.onServerReady = run.bind(this, function(){
  app.server.close()
  process.exit(0)
}) 

Dont forget to chmod 755 test/tests/mytest.js in the console

That's it!

Now just run npm test or ./test/tests/mytest.js and your test(s) will run
