Mocking Passport OAuth for integration tests

Install

npm install cobbler --save-dev

Usage

Stratgies

var passport = cobbler('passport-github', {..profile..});

var server = app.listen(7331, function() {
  new WalkingDead(url).zombify(zopts)
    .when(function(browser, next) {
      browser.clickLink('[rel="login-with-github"]', next);
    })
    .then(function(browser) {
      assert.equal(browser.text("title"), "Welcome!");
    })
    .end(function() {
      passport.restore();
      server.close();
      done();
   });
});

cobbler mocks the calls to the OAuth service and redirects you to the callback url allowing you to bypass the network connections, but allows you to go through the full (most of it at least) process without mocking key functions in managing sessions, authenticated or initialization of passport.

---

If you want to simulate a successful authentication, the "profile" argument should be an object similar to what you would receive from an OAuth userProfile call. This will hit your Strategy callback and go through the normal chain of events.

var passport = cobbler('passport-github', {
  provider: 'github',
  id: 12345,
  displayName: 'John Doe'
});

To simulate a failed authentication, the "profile" argument should be false.

var passport = cobbler('passport-github', false);

Login Session

cobbler provides a way to "login as a user" without actually going through the actual login (above).

var passport = cobbler('session', '12345');

Note the first agrument string 'session' (case-sensitive). The 2nd argument should be the object that is passed to the passport.deserializeUser method. ex.

passport.deserializeUser(function(id, done) {
  User.findOne({_id: id})
    .exec(function(err, resource) {
      if (err) {
        return done(err, null);
      }
      done(null, resource);
    });
});

id would be a user.id.

---

Your passport.deserializeUser will actually be invoked

Restoring

You can restore the old functions by calling restore().

var passport = cobbler('passport-github', {..profile..});

// do the test

passport.restore();

API

cobbler, for stratgies, can be passed either the npm name eg. 'passport-github' or the exports eg. var passportGithub = require('passport-github'); or the strategy eg. var GithubStrategy = require('passport-github').Strategy;

For sessions, the first argument must be "session".

---

It should be noted that you may need to clear the require.cache of your app between tests.

TODO

• More test coverage for other Passport Strategies, especially non-OAuth strategies.
• Ability to set arguments such as accessToken, refreshToken, params
• Ability to test fail and error calls.
• Ability to set callback url code and error query params
