在创建表之前完成了Jest / TypeORM测试

Question

似乎我编写的测试在表创建之前被调用。 实际上，在测试中调用的计数是在创建表之前完成的，然后服务器启动并重新进行测试。

我以前没有看到这种行为，我搜索了几个小时，但没有找到任何可能导致这种情况的原因。

setup.ts

beforeAll(async () => {
    const connectionManager = getConnectionManager()
    const connection = connectionManager.create({
        type: 'postgres',
        host: 'localhost',
        port: 54320,
        username: 'test',
        password: 'test',
        database: 'bitsky_test',
        entities: ['../src/entities/*.ts'],
        logging: true,
        synchronize: true,
    })
    await connection.connect()
})

afterAll(async () => {
    await getConnection().dropDatabase()
    await getConnection().close()
})

app.ts

const version: string = '0.0.1'
const mode: string = 'Development'
const port: number = 5030

export const startApp = () => {
    dotenv.config()
    const router: Application = express()

    applyMiddleware(commonMiddlewares, router)

    router.use('/auth', authRouter())

    return router
}

createConnection().then(() => {
    startApp().listen(port, () => {
        ServerLogger.log(serverGreetings, logLevels.MISC)
        ServerLogger.log(`Version: ${version} ${mode} mode\n`, logLevels.MISC)
        ServerLogger.log(`Server running on port ${port}!`)
    })
})

测试调用的方法

const repository: Repository<User> = getRepository(User)

// Check unique email
const emailTaken: number = await repository.count({ where: { email: data.email }})

if (emailTaken) {
    return Boom.badRequest('email_already_taken')
}

// Hashing password
const saltRounds: number = parseInt(`${process.env.SALT_ROUNDS}`, 10)
const clearPassword: string = data.password
data.password = await bcrypt.hash(clearPassword, saltRounds)

// Saving user
const user: User = repository.create(data)
await repository.save(user)

// Generating token & deleting password
return authenticate(data.email, clearPassword)

测试     const app = startApp（）

describe('POST /auth/create', () => {
    it('Create a user', async () => {
        const user: IStringTMap<string> = {
            firstName: 'John',
            lastName: 'Doe',
            email: 'john.doe@bitsky.be',
            password: 'iliketrains!',
        }

        const res: Response = await request(app)
            .post('/auth/create')
            .send(user)
            .expect(200)

        expect(res.body.email).toBe('john.doe@bitsky.be')
        expect(res.body.password).toBe(undefined)
    })
})
