使用 sinon-ts 存根 Meteor user 和 userId

Question

我想使用 sinon-ts 存根 user 和 userId 以便我可以测试从数据库获取结果的服务器端代码。

如果我使用纯 sinon，我可以正确地存根 user 和 userId 并且测试通过。虽然它通过 Webstorm 显示 returns 方法不存在等错误，所以我认为它在 Typescript.

中表现不佳

sinon - 传球

import {Factory} from 'meteor/dburles:factory';
import {Meteor} from 'meteor/meteor';
import {resetDatabase} from 'meteor/xolvio:cleaner';
import {GiftListCollectionManager} from "../imports/api/collections/GiftListCollection";
import User = Meteor.User;
import { sinon } from 'meteor/practicalmeteor:sinon';

describe("Test", function () {
    beforeEach(() => {
        resetDatabase();
        Factory.define('user', Meteor.users, {

        });
        currentUser = Factory.create('user');
        sinon.stub(Meteor, 'user');

        Meteor.user.returns(currentUser);

        sinon.stub(Meteor, 'userId');

        Meteor.userId.returns(currentUser._id);
    });

    afterEach(() => {
        Meteor.user.restore();
        Meteor.userId.restore();
        resetDatabase();
    });

    it("Gets giftlists based on Meteor.userId()", () => {
        console.log("Gift lists")
        console.log(GiftListCollectionManager.getInstance().getGiftLists());
    })
}

我决定尝试 sinon-ts，这样我就不会显示任何语法错误。我似乎无法正确地存根 user 和 userId。

sinon-ts - 失败

import {Meteor} from 'meteor/meteor';
import {resetDatabase} from 'meteor/xolvio:cleaner';
import {GiftListCollectionManager} from "../imports/api/collections/GiftListCollection";

import * as sinon from "ts-sinon";

describe("Test", function () {

    let currentUser;

    beforeEach(() => {
        resetDatabase();
        Factory.define('user', Meteor.users, {

        });
        currentUser = Factory.create('user');

        const userStub = sinon.stubObject(Meteor);

        userStub.user.returns(currentUser);

        const userIdStub = sinon.stubObject(Meteor);

        userIdStub.userId.returns(currentUser._id);
    });


    it("Gets giftlists based on Meteor.userId()", () => {
        console.log("Gift lists")
        console.log(GiftListCollectionManager.getInstance().getGiftLists());
    })
});

我花了很多时间环顾四周，但找不到任何关于使用 sinon-ts.

对 Meteor user 和 userId 进行处理的人

获得相同结果的正确方法是什么？

更新

使用 callsFake 抛出异常

import sinon = require('sinon');
sinon.stub(Meteor, 'user').callsFake(() => currentUser);
sinon.stub(Meteor, 'userId').callsFake(() => currentUser._id);

错误

TypeError: sinon.stub(...).callsFake is not a function

Answer 1

事实证明，sinon-ts 围绕 sinon 实施了“扩展”，以使其更好地与 TypeScript 配合使用，但它仍然支持“默认”sinon 行为。

已知 function stubs 可以与 Meteor.user() 和 Meteor.userId() 一起使用，并且可以通过

访问

import sinon, { stubInterface } from "ts-sinon";

const functionStub = sinon.stub();

或通过

import * as tsSinon from "ts-sinon"

const functionStub = tsSinon.default.stub();

将此方案应用于您当前的代码将产生以下代码，该代码有望与 Meteor 的用户函数一起使用：

import {Meteor} from 'meteor/meteor';
import * as sinon from "ts-sinon";
// ... other imports

describe("Test", function () {
    let currentUser;

    beforeEach(() => {
        resetDatabase();
        Factory.define('user', Meteor.users, {

        });
        currentUser = Factory.create('user');

        sinon.default.stub(Meteor, 'user').callsFake(() => currentUser);
        sinon.default.stub(Meteor, 'userId').callsFake(() => currentUser._id);
    });

    // ... test units
});
