【中文标题】用 Apollo-server 和 Prisma 2 开玩笑【英文标题】：Jest with Apollo-server and Prisma 2 【发布时间】：2020-10-10 16:11:48 【问题描述】：我想知道如何将 JEST 与 Prisma 2 一起使用？
当我执行我的简单测试时，我遇到了一个奇怪的错误：
npm run test

> env-cmd -f ./env/.env.test jest --watchAll

A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --runInBand --detectOpenHandles to find leaks.

我使用以下命令启动测试：
npm run test
来自 packages.json 的 Jest 配置：
"scripts":
"test": "env-cmd -f ./env/.env.test jest --watchAll"
,
"jest":
"globalSetup": "./tests/jest/globalSetup.js",
"globalTeardown": "./tests/jest/globalTeardown.js"
,
server.js
...
const server = new ApolloServer(
typeDefs,
resolvers,
context(request)
return
prisma,
request,
,
)
export server as default
./tests/jest/globalSetup.js
require("@babel/register")
const server = require("../../server").default
module.exports = async () =>
global.httpServer = await server.listen( port: 4000 )
./tests/jest/globalTeardown.js
module.exports = async () =>
await global.httpServer.server.close()
user.test.js
import "cross-fetch/polyfill"
import ApolloBoost, gql from "apollo-boost"
import PrismaClient from "@prisma/client"
const prisma = new PrismaClient()
const client = new ApolloBoost(
uri: "http://localhost:4000",
)
/* beforeEach(async () =>
await prisma.user.deleteMany()
) */
test("Should create a new user", async () =>
// console.log(prisma)
const createUser = gql`
mutation
createUser(
data:
name: "Test"
email: "test@example.com"
password: "Password123"
)
token
user
id
`
const response = await client.mutate(
mutation: createUser,
)
const exists = await prisma.user.findOne(
where:
id: parseInt(response.data.createUser.user.id, 10),
,
)
// expect(exists.email).toBe("test@example.com")
)
突变有效，但我无法执行 prisma.user.findOne...

【问题讨论】：
【参考方案1】：我在this repo 中使用 Prisma 添加了集成测试。您可以在prisma 文件夹中找到设置，在tests 文件夹中找到测试。
【讨论】：
感谢@Ryan 的回答！我尝试测试我的数据库（例如，如果数据库中存在插入）不仅响应以上是关于用 Apollo-server 和 Prisma 2 开玩笑的主要内容，如果未能解决你的问题，请参考以下文章

我不能在 apollo-server 中创建一个 rest API 吗？
