[英]MongoDB connetion will not close in Jest afterAll()
這是我的設置和拆卸方法的當前 state:
beforeAll(async () => {
// await populate();
try {
await client.connect(() => console.log("Connection opened"));
const db = client.db('trallo');
const cards = db.collection('cards');
const hello = {
title: "Hello",
description: "Goodbye"
};
const card = await cards.insertOne(hello);
const todo = {
title: "Todo",
cards: [card.insertedId]
}
const inProgress = {
title: "In progress",
cards: []
}
const done = {
title: "Done",
cards: []
}
const lists = db.collection('lists');
const list = await lists.insertMany([todo, inProgress, done]);
const dummy = {
title: "Dummy",
lists: Object.keys(list.insertedIds).map(key => list.insertedIds[key])
}
const boards = db.collection('boards');
const board = await boards.insertOne(dummy);
} finally {
// Ensures that the client will close when you finish/error
await client.close(() => console.log("Connection closed"));
// done();
}
});
afterAll(async () => {
// await deleteAll();
try {
await client.connect(() => console.log("Connection opened"));
const db = client.db('trallo');
const cards = db.collection('cards');
await cards.deleteMany({});
const lists = db.collection('lists');
await lists.deleteMany({});
const boards = db.collection('boards');
await boards.deleteMany({});
} finally {
// Ensures that the client will close when you finish/error
await client.close(() => console.log("Connection closed"));
// done();
}
});
我試過增加超時時間,在連接打開和關閉的地方四處移動,在測試和設置/拆卸中都傳遞了一個“完成”回調,到目前為止沒有任何效果。
這是運行 jest 時我得到的:
RUNS functional-tests/homepage.test.js
測試套件:1 個失敗,總共 1 個測試:1 個失敗,總共 1 個快照:0 個總時間:1.218 秒,估計 6 秒運行所有匹配 /functional-tests/i 的測試套件。
Jest 檢測到以下 2 個打開的句柄可能會阻止 Jest 退出:

嘗試編寫測試,就像連接到數據庫時在 Jest 文檔中所做的一樣,可能會有所幫助: https://jestjs.io/docs/mongodb
因此,而不是(我假設client
是MongoClient
的new
實例):
beforeAll(async () => {
try {
await client.connect(() => console.log("Connection opened"));
const db = client.db('trallo');
// ...rest of the code
嘗試等待MongoClient
並像這樣立即連接:
describe('Your test', () => {
let connection;
let db;
beforeAll(async () => {
try {
connection = await MongoClient.connect("YOUR_MONGO_URI");
db = await connection.db("trallo");
// ...rest of the code
