Throwing error with Jest and react-test-renderer

[lucasbento]

I'm experiencing a few problems on trying to use this package with Jest and react-test-renderer, these are my files:

// setup.js
const mySchema = `
type User implements Node {
  id: ID!
  _id: String
  myself: Boolean
  name: String
  nick: String
  email: String
  active: Boolean
}
`;

const networkLayer = new RelayMockNetworkLayer(mySchema);

RelayStore.reset(networkLayer);

// MyComponent.spec.js
import 'react-native';
import React from 'react';
import renderer from 'react-test-renderer';

import MyComponent from '../MyComponent';

describe('<MyComponent />', async () => {
  it('should render without blowing up', async () => {
    const result = renderer.create(<MyComponent />);

    expect(result.toJSON()).toMatchSnapshot();
  });
});

Throws this:

Must provide a schema definition.

I changed the version of graphql-tools to use 0.11.0 which throws:

I think this project need an update, it hasn't been updated in 8 months. I'd suggest you first try to make your schema work with mockServer, if that works it means I need to update this project to support the latest graphql tools

Thank you for answering back!

It actually seems to work with mockServer but it throws an error on relay-mock, the stacktrace that I sent is not very clear, the errors start here:

  sendQuery = queryRequest => {
    const query = queryRequest.getQueryString(); // <-- here
    const variables = queryRequest.getVariables(); // <-- and here

    return this.server.query(query, variables).then(({ data }) => queryRequest.resolve({ response: data }));
  };

what version of relay are you using?

[lucasbento]

0.10.0.

this example repo https://github.com/sibelius/relay-integration-test

has a working version against a real graphql server

I'll try to modify it to test against a mocked server as well
