开玩笑超时错误：测试超时超过 5000 毫秒

Question

我已经为控制器创建了一个单元测试用例，并在运行测试用例时模拟请求、响应和下一步，它会抛出笑话超时错误。

谁能帮我解决这个问题。

员工.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 }

员工.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)
    });
});

对我有用的一种方法是将超时值增加到适合您需要的数字； 在此示例中为 60 秒：

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

对于 CRA 用户，我们可以将

jest.setTimeout(ms)

放入

setupTests

文件中，以增加全局超时，以防其他测试因相同原因失败。
