Reading Environment specific variables from test file Compound.js

Question

I'm working on a compound js app. In environments/test.js I have exported a variable as follows:

app.host = "http://mysite.com"

When I run the app as below:

NODE_ENV=test node .

I could access the value of host by giving app.host. Everything is fine till here.

I'm using mocha for testing. When I try to access app.host from my test file, I'm getting an error saying,

ReferenceError: app is not defined.

Any idea on how to access the variables from environment/test.js file from test/*.js files would be helpful. Thanks in advance.

Answer 1

environments/test.js

module.exports = {
  host: "http://example.com"
};

app.js

var app;

if (process.env.NODE_ENV === "test") {
  app = require("./environments/test.js");
}

console.log(app.host);

If you load the module at the top of the Mocha test it should be OK.
