使用mocha和超级测试进行NodeJS HTTPS API测试 - “DEPTH_ZERO_SELF_SIGNED_CERT”

Question

I need to test an API served via HTTPS with mocha and super test (the certificate are not expired)

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

just for everyone else who is also wondering what to do. Add thison top of your test.js and you will be fine:

process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';
