node.js - Use different database for the npm test phase -

environment: heroku, node.js - express, testing mocha.

how can configure heroku launch npm test node_env="test" , invoke server ("node server.js") node_env="production" .

this means need 2 server invocations - once testing (where connect test db) , once production (where connect production db)

i want use different db in "npm test" phase since tests create fake data.

here how test like:

var supertest = require("supertest"); var should = require('chai').should(); var config = require('../server/config');  var server = supertest.agent(config.baseurl);  describe("user controller", function () {     describe("http verbs", function () {          it("get", function (done) {               console.log(config.dburl);               console.log(config.baseurl);               server.post("/api/user") {                   .send(utils.createmockeduserplainobject())                   .end(function(err, res) {                    server.get("/api/user/list")                     .expect("content-type", /json/)                     .expect(200) // http response                     .end(function (err, res) {                         // http status should 200                         res.status.should.equal(200);                         res.body.should.have.length(1);                          done();                   });               })           });     }); }); 

well,

its seems magic lies inside supertest.

replace:

var server = supertest.agent(config.baseurl); 

with:

var app = require('../server');  var server = supertest.agent(app);
