How we use a mocking provider to mock data

apollo-mocking-provider.jsx

import TodoList from './TodoList';

// Specify some resolvers for this instance
const customResolvers = {
  Query: () => ({
    todoItems: [
      { completed: true },
      { completed: false },
    ]
  })
};

// TodoList uses the following query:
// query {
//   todoItems {
//     text
//     completed
//     owner { name }
//   }
// }
<ApolloMockingProvider customResolvers={customResolvers}>
  <TodoList />
</ApolloMockingProvider>
