NodeJS HTTPS API testing with mocha and super test -“CERT_HAS_EXPIRED”

Question

I need to test an API served via HTTPS with mocha and super test

This is a gist of the server :

...
var app = express();
var _options = {
    key: fs.readFileSync('my-key.pem');,
    cert: fs.readFileSync('my-cert.pem')
};

// Start HTTPS server
https.createServer(_options, app).listen(app.get('port'), app.get('ip'), function () {

 // ok or not logs

});

and this is the route to be tested

app.get('/hello',function (req, res) {
   res.json(200);
});

I'm trying to test with this code in test/test.js

    var supertest = require('supertest'),
        api = supertest('https://localhost:3000');

describe('Hello test', function () {

      it('hello', function (done) {

        api.get('/hello')
               .expect(200)
               .end(function (err, res) {
                                        if (err) {
                                                   done(err);
                                        } else {
                                                   done();
               }
         });
    });
});

but the test FAILs with the following error :

While using plain HTTP the test is PASSING

Answer 1

Have you taken the error message at face value already? Is the certificate you are using to test expired? Is the clock way off on the machine? Also note that TLS certificates are associated with a host name and that host name is generally not "localhost" if you want to do anything useful. Assuming it's not the obvious error of the certificate being expired, try using exactly the correct hostname when connecting to your server.
