建议替换已过时的GraphQL测试客户端

建议使用Apollo Client来代替GraphQL Test Client。以下是一个使用Apollo Client进行GraphQL测试的示例代码：

import { ApolloClient } from 'apollo-client';
import { InMemoryCache } from 'apollo-cache-inmemory';
import { HttpLink } from 'apollo-link-http';
import gql from 'graphql-tag';

const client = new ApolloClient({
  cache: new InMemoryCache(),
  link: new HttpLink({
    uri: 'https://api.example.com/graphql',
  }),
});

client.query({
  query: gql`
    query GetUser($id: ID!) {
      user(id: $id) {
        name
      }
    }
  `,
  variables: {
    id: '123',
  },
}).then(response => {
  console.log(response.data.user.name);
});
