用NestJS测试mongoose模型

import { Schema, model } from 'mongoose';

export interface User {
  name: string;
  email: string;
}

const UserSchema = new Schema<User>({
  name: { type: String, required: true },
  email: { type: String, required: true },
});

export const UserModel = model<User>('User', UserSchema);

import { Test, TestingModule } from '@nestjs/testing';
import { getModelToken } from '@nestjs/mongoose';
import { Model } from 'mongoose';
import { User, UserModel } from './user.model';

describe('UserModel', () => {
  let userModel: Model<User>;

  beforeEach(async () => {
    const module: TestingModule = await Test.createTestingModule({
      providers: [
        {
          provide: getModelToken('User'),
          useValue: UserModel,
        },
      ],
    }).compile();

    userModel = module.get<Model<User>>(getModelToken('User'));
  });

  afterEach(async () => {
    await userModel.deleteMany({});
  });

  it('should create a user', async () => {
    const user: User = { name: 'John Doe', email: 'john@example.com' };
    const createdUser = await userModel.create(user);

    expect(createdUser.name).toEqual(user.name);
    expect(createdUser.email).toEqual(user.email);
  });
});
