如何检查数组和类型？

Question

const userOverviewType = new GraphQLObjectType({ 
    name: 'dayOverviewData', 
    fields:() => ({ 
     users: { 
      type: new GraphQLList(user), 
     }, 
    }), 
}); 

我想在chai中测试这个对象类型。我的测试是：

expect(userOverviewType.getFields().users.type).to.deep.equals([ user ]); 

测试失败：

1) User userOverviewType Should have a days field of type GraphQLList: 
     AssertionError: expected [user] to deeply equal [ user ] 
      at Assertion.assertEqual (node_modules/chai/lib/chai/core/assertions.js:485:19) 
      at Assertion.ctx.(anonymous function) [as equals] (node_modules/chai/lib/chai/utils/addMethod.js:41:25) 
      at Context.<anonymous> (src/test/station.server.spec.js:133:65) 

如何才是正确的代码？

Answer 1

柴测试的类型是错误的。正确的测试是：

expect(userOverviewType.getFields().users.type).to.be.an.instanceof(graphql.GraphQLList); 
expect(graphql.getNamedType(userOverviewType.getFields().users.type)).to.deep.equals(userData.user);
