testing local https server with mocha/superagent - node.js

Question

So I see there was a pull request a few months ago for superagent to allow you to specify the CA in a request. It does not appear that the docs were updated to reflect this change, so I can't seem to figure out how to do it.
I am trying to test on my local machine a REST service which exposes both http and https endpoints. All the http ones work fine, the SSL ones....well.....not so much.
After spending all day yesterday running down certificate errors, I am 90% certain I have the server working correctly. Curl seems to think so, as does a vanilla node request object.
I assume superagent is probably creating a request under the hood - I just need to know how to pass in the CA for it.
Thanks in advance.

Answer 1

There is a usage example in their tests.
Basically:
var https = require('https'),
fs = require('fs'),
key = fs.readFileSync(__dirname + 'key.pem'),
cert = fs.readFileSync(__dirname + 'cert.pem'),
assert = require('better-assert'),
express = require('express'),
app = express();
app.get('/', function(req, res) {
res.send('Safe and secure!');
});
var server = https.createServer({
key: key,
cert: cert
}, app);
server.listen(8443);
describe('request', function() {
it('should give a good response', function(done) {
request
.get('https://localhost:8443/')
.ca(cert)
.end(function(res) {
assert(res.ok);
assert('Safe and secure!' === res.text);
done();
});
});
});

This worked for me:
...
var user = request.agent({ca: cert});
...
Full example:
var expect = require('chai').expect;
var should = require('should');
var request= require('superagent');
var fs = require('fs');
var cert = fs.readFileSync('sslcert/server.crt', 'utf8');
var validUser = { username: 'test#test.com', password: 'secret111' };
describe('User', function() {
// provide certificate as agent parameter
var user = request.agent({ca: cert});
it("/login", function(done) {
user
.get('https://localhost:3000/login')
.end(function(err, res) {
if(err) throw err;
// HTTP status should be 200
res.status.should.equal(200);
user
.post('https://localhost:3000/login')
.send(validUser)
.end(function(err, res) {
if(err) throw err;
// HTTP status should be 200
res.status.should.equal(200);
done();
// user will manage its own cookies
// res.redirects contains an Array of redirects
});
});
});
it("/", function(done) {
user
.get('https://localhost:3000/')
.end(function(err, res) {
if(err) throw err;
// HTTP status should be 200
res.status.should.equal(200);
done();
});
});
it("/logout", function(done) {
user
.get('https://localhost:3000/logout')
.end(function(err, res) {
if(err) throw err;
// HTTP status should be 200
res.status.should.equal(200);
done();
});
});
});
