Jest 调用了模块的导入依赖链

Question

当我创建 Atom jest 实例时，我没有调用一段代码显示错误。我假设它连接了我尝试创建的 class 中导入的模块。我开始模拟错误显示的模块，每个模拟模块错误都已更改，但结果它给我带来了第一个错误。如何解决？

示例中的测试工作正常，但 Atom 的创建抛出错误。 Atom.test.ts

import { Atom } from '../flowmanager/atom/Atom';
import Bot from './Bot';

describe('Atom ->', () => {
    const atom = new Atom({ name: 'Atom name' });

    const bot = new Bot({ name: 'daniel' });

    it('getName', () => {
        expect(bot.getName()).toBe('daniel');
    });
});

Atom.ts

import emojiStrip = require('emoji-strip');
import { Message } from '../messages/Message';
import MessageRandom from '../messages/MessageRandom';
import UserInputMessage from '../messages/types/UserInput';
import ConditionMessage from '../messages/types/Condition';
import { Session } from '../../user/session/Session';
import MessageTypes from '../../constants/MessageTypes';

export class Atom {
    public data: any;

    constructor(data = {}) {
        this.setData(data);
    }

    setData(data: any) {
        if (!_.isArray(data.messages)) {
            data.messages = [];
        }
        this.data = data;

        this.data.messages = _.map(this.getMessages(), message => {
            if (_.isArray(message.messages)) {
                message.messages = message.messages.map((nestedMessage: any) => new Message(nestedMessage));
            }
            return _.get(message, 'options.random') ? new MessageRandom(message) : new Message(message);
        });
    }

    findReply(userInput: any, session: Session) {
        return _findReply.call(
            this,
            (reply: any) => {
                if (!reply.content.text) return false;
                const preparedReplyText = emojiStrip(reply.content.text.replace(/\?/g, '')).trim().toLowerCase();
                return preparedReplyText === userInput.trim().toLowerCase();
            },
            session
        );
    }

    findReplyById(replyId: any, session: Session) {
        return _findReply.call(this, (reply: any) => reply._id === replyId, session);
    }

    getNextAtomIdByReply(input: any, session?: any) {
        const reply: any = this.findReply(input, session);
        if (!reply) {
            return null;
        }

        return this.getNextAtomIdByReplyId(reply._id, session);
    }

    getNextAtomIdByReplyId(replyId: any, session: Session) {
        const reply = this.findReplyById(replyId, session);

        return _.get(reply, 'nextAtom');
    }

    getName() {
        return this.data.name;
    }

    getId() {
        return this.data._id;
    }

    getFlow() {
        return this.data.flow;
    }

    getBotId() {
        return this.data.bot;
    }

    // eslint-disable-next-line @typescript-eslint/no-unused-vars
    getMessages(session?: any) {
        return this.data.messages;
    }

    getReference() {
        return this.data.shortReference || this.data.reference;
    }

    isActive() {
        return this.data.disabled !== true;
    }

    isRoot() {
        return this.data.root === true;
    }

    needLogin() {
        return _.get(this.data, 'flow.needAuth') || _.get(this.data, 'options.needAuth');
    }

    getUserInputMessage() {
        const message = _.find(this.getMessages(), message => message.type === 'userInput');
        if (!message) {
            return null;
        }

        return new UserInputMessage(message);
    }

    getConditionMessage(session: Session, onReply = false) {
        const conditionMessage = _.find(this.getMessages(session), ({ type }) => type === MessageTypes.CONDITION);
        if (!conditionMessage || _.get(conditionMessage, 'options.condition.onReply', false) !== onReply) {
            return null;
        }
        return new ConditionMessage(conditionMessage);
    }

    canReturn() {
        return _.get(this.data, 'options.canReturn', true);
    }

    getOption(field: string) {
        return _.get(this.data, `options.${field}`);
    }

    public getEmailEvent = () => {
        return this.data.options?.emailEvent;
    };
}

按照评论中的建议，只需要模拟Atom模块中的所有导入

Jest 调用了模块的导入依赖链

Jest called chain of imported dependencies of module

typescript

unit-testing

jestjs

ts-node
