Example using GraphQL and React Native for Testing

[Freire71]

Hi, I'm trying to integrate MirageJS in a existing React Native app that uses Apollo Client as it GraphQL client.
Using MirageJS for development works great, however inside test files I'm having some troubles to make it work.
Could you please provide an example for a React Native app that uses the GraphQL package?

Still having the same issue, It would be great to have an example talking about how to make it work for testing :)

Hi, I've found why my code was not working for testing, I've needed to add global.FormData = class FormData {} on jest.setup.js. This line of Pretender throws because FormData in undefined
whatwg-fetch is used because Apollo client is using the React Native implementation of fetch API but it does not exists for Node env.
This my final version of the jest.setup.js file

import 'whatwg-fetch';
global.self = global;
global.XMLHttpRequest = require('xmlhttprequest').XMLHttpRequest;
global.FormData = class FormData {};
