我当前正在使用Apollo服务器作为我选择的GraphQL服务器，并且每当我尝试运行测试时，都会出现标题中指示的错误。但是，我的服务器实现按预期工作。
import 'cross-fetch/polyfill';
import ApolloClient,{ gql } from 'apollo-boost';
const client = new ApolloClient({
uri: 'http://localhost:4000/',});
const USER = {
invalidPassWord : {
name: 'Gbolahan Olagunju',password: 'dafe',email: 'gbols@example.com'
},validCredentials: {
name: 'Gbolahan Olagunju',password: 'dafeMania',usedEmail: {
name: 'Gbolahan Olagunju',email: 'gbols@example.com'
}
};
describe('Tests the createUser Mutation',() => {
test('should not signup a user with a password less than 8 characters',() => {
const createUser = gql`
mutation {
createUser(data: USER.invalidPassWord){
token
user {
name
password
email
id
}
}
}
`
client.mutate({
mutation: createUser
}).then(res => console.log(res));
})
})
