開玩笑超時錯誤：超過 5000 毫秒的測試超時

Question

我為 controller 和 mocking 創建了一個單元測試用例，請求、響應和下一個在運行測試用例時拋出了開玩笑超時錯誤。

任何人都可以幫我解決這個問題。

員工.controller.ts

import { Request, Response, NextFunction } from 'express';
import { employeeService } from './employee._service';

const empServices = new employeeService();

module employeeController {
    export async function getEmployee(req: Request, res: Response, next: NextFunction) {
        try {
            const result = await empServices.getEmployee();
            res.send(result);
            return result;
        }
        catch (err) {
            console.log(err);
            res.statusCode = 200;
            res.send("error in getEmployee: " + err);
        };
    };
}
export { employeeController }

員工.controller.spec.ts

import { Request, Response, NextFunction } from 'express';
import { employeeController } from '../employee.controller';
import { employeeService } from '../employee._service';

describe("should return pong message", () => {
    const service = new employeeService();
    it("should return pong message", async () => {

        const mockRequest: any = {
            body: jest.fn(),
            params: jest.fn()
        };

        const mockResponse: any = {
            json: jest.fn(),
            status: jest.fn(),
        };

        const mockNext: NextFunction = jest.fn();

        const spy = jest.spyOn(service, 'getEmployee').mockResolvedValueOnce([]);
        const comments = await employeeController.getEmployee(mockRequest, mockResponse, mockNext);
        expect(comments).toEqual([]);
        expect(spy).toHaveBeenCalledWith()
        expect(spy).toHaveBeenCalledTimes(1)
    });
});

錯誤截圖

謝謝

一種對我有用的方法是將超時值增加到適合您需要的數字； 在本例中為 60 秒：

beforeEach((): void => {
    jest.setTimeout(60000);
    ...
  });

對於 CRA 用戶，我們可以將jest.setTimeout(ms)放在setupTests文件中，以在其他測試因相同原因失敗的情況下全局增加超時。
