chai-passport-strategy

Helpers for testing Passport strategies with the Chai assertion library.

Install

$ npm install chai-passport-strategy

Usage

Use Plugin

Use this plugin as you would all other Chai plugins:

var chai = require('chai');

chai.use(require('chai-passport-strategy'));

Implement Test Cases

Once used, the chai.passport.use helper function will be available to set up a test case which places a Passport strategy under test.

The helper returns a wrapper on which callbacks are registered to be executed when the strategy invokes its final action function. The callbacks correspond to Passport's strategy API: success(), fail(), redirect(), pass(), and error(). If the strategy invokes an action that doesn't have a registered callback, the test helper will automatically throw an exception.

For example, a Mocha test case that tests a strategy which implements bearer token authentication:

it('should authenticate request with token in header', function(done) {
  chai.passport.use(new Strategy(function(token, cb) {
      expect(token).to.equal('mF_9.B5f-4.1JqM');
      return cb(null, { id: '248289761001' }, { scope: [ 'profile', 'email' ] });
    }))
    .request(function(req) {
      req.headers['authorization'] = 'Bearer mF_9.B5f-4.1JqM';
    })
    .success(function(user, info) {
      expect(user).to.deep.equal({ id: '248289761001' });
      expect(info).to.deep.equal({ scope: [ 'profile', 'email' ] });
      done();
    })
    .authenticate();
});
