legacySession is completely broken

[coreyog]

I want to use supertest-session to test a non-Express API. In my original code, I'd have this line:

request('http://www.google.com').get('/asdf').expect(404).end(done);

I get an error along the lines of "undefined is not a function." Through a little debugging, I found that it thought request("...").get is undefined. So I opened up the module and found this in the module.exports function:

if (typeof app != 'function') {
  return deprecatedLegacySession(app);
}

deprecatedLegacySession calls:

function legacySession (config) {
  if (!config) config = {};

  // Bind session to `config`
  function LegacySession () {
    Session.call(this, config.app, config);
  }

  util.inherits(LegacySession, Session);
  assign(LegacySession.prototype, {}, config.helpers);

  return LegacySession;
}

And there's a lot of issues with this. First, config is the app string I passed in and is not used properly as the string. The function returns the inner LegacySession function, it should create a new instance of the LegacySession instead of returning the function. That doesn't matter because the LegacySession is messed up. It tries to get config.app but config is a string. The whole legacySession function should be:

function legacySession (app, config) {
  if (!config) config = {};

  // Bind session to `config`
  function LegacySession () {
    Session.call(this, app, config);
  }

  util.inherits(LegacySession, Session);
  assign(LegacySession.prototype, {}, config.helpers);

  return new LegacySession();
}

Or, an even easier solution, completely remove the if (typeof app != 'function') {...} check out of your module.exports function. Doing so means I can properly use request("http://www.google.com") as advertised.

No good at all—thanks, @coreyog, for the detailed report!

#17 adds a failing case for this issue and fixes it by tightening down the compatibility conditions. If you have a sec to verify that it addresses the issue, we'll merge and get this closed out.

It looks like that'll do the trick.

Patch is merged and pushed to npm as v1.1.2—thanks again, @coreyog, and happy testing!
