Integration tests does not work with call

[a9a4k]

I have the following setup in mocha:

describe('Falcor requests', function() {
  let server;
  before(function() {
    const app = express();
    app.use(routes);
    model = new falcor.Model({
      source: new HttpDataSource('http://localhost:1337/model.json')
    });
  });
  after(function() {
    server.close();
  });
  it('should retrieve deals', function() {                                             // model.get works
    return model.get(['dealsById', testDeal1.id, 'title']).
    then(res => {
      expect(
        res.json.dealsById[testDeal1.id].title
      ).to.equal(testDeal1.title);
    });
  });
it('should create a user with a call function and return its values', function() {         // model.call works
    const args = {
      ...
    };
    return model.call(
      ['users', 'create'],
      [args],
      ['email']
    ).
    then(res => {
      console.log(res, 'response');
    });
  });

All the gets are tested perfectly, however on call test throws Request not supported, pointing to the xmlhttprequest lib.

Could you please advise me on what to do?

From what I can tell, this should be perfectly fine. I think I would need to see more of the program. Could you include routes and the call function you are attempting to call? That would be grand!

I know you are suppose to use a listen function at some point with an express server. I don't see that being executed. Make sure that the routes support post as well, as call uses post.

@michaelbpaulson I have the following structure:

express-routes.js

...
router.all(
  '/model.json',
  authenticate,
  falcorExpress.dataSourceRoute(req => new ClientRouter(serverModel, req.user ? req.user.sub : null))
);
...

client-router.js

...
class ClientRouter extends Router.createClass([
  ...
  {
    route: 'users.create',
    call(...args) {
      // TODO for now it is ok, as call returns undeined,
      // but when refPaths will start working, will have to rewrite
      return this.serverModel.
        call(...args).
        map(json => toPathValues(json));
    }
  },
]) {
  constructor(serverModel, userId) {
    super();
    this.serverModel = serverModel;
    this.userId = userId;
  }
}
...

@michaelbpaulson Call actuall works, when called from the webpage, it does not work when I call from tests...

[a9a4k]

@michaelbpaulson I actually do call

return new Promise((resolve, reject) => {
            server = app.listen(1337, err => {
              if (err) {
                reject(err);
                return;
              }
              resolve();
            });
          })

at the end of the before function in mocha. I was just cutting code for it to be shorter and removed necessary stuff :)

This I have no Idea. This is a problem that I would have to debug myself to figure out. All i know is Request not supported is not a falcor error. Have you made any progress on this? @gdi2290 do you have any idea? Could this have to do with falcor-http-datasource?

@almasakchabayev Is this still a problem for you? Wanted to check in and see if there's anything we can do to help. See @michaelbpaulson's comment from 1/20.

@ktrott For some reason I could not make it work with a call. I tried to dig into the source code and I guess that problem lies in xmlhttprequest lib
