Question

我正在尝试使用Mocha的done函数测试异步中间件auth函数。但是，似乎在异步调用中调用完函数之前，测试已完成。测试不应该等到完成的回调被调用吗？

中间件：

const AuthMiddleware = (req: Request, res: Response, next: NextFunction) => {
    const token = getToken(req)

    if (token === undefined) {
        res.status(401)
        next()
    }

    jwt.verify(token, getSigningKey, (err, decodedToken) => {
        if (err) {
            res.status(401)
            next()
        }
    })
}

我的测试：

describe("AuthMiddleware", () => {
    it("Should return 401 if token is expired", (done) => {
        const options = { headers: { authorization: "Bearer " + expiredToken } }
        const req = mockReq(options) as Request
        const res = mockRes() as Response

        AuthMiddleware(req, res, done)
        expect(res.status).to.have.been.calledWith(401)
    }).timeout(10000)
})

您将done（）视为next（）。完成用于结束测试，而下一步用于中间件

describe("AuthMiddleware", () => {
it("Should return 401 if token is expired",async (done) => {
    const options = { headers: { authorization: "Bearer " + expiredToken } }
    const req = mockReq(options) as Request
    const res = mockRes() as Response

    await AuthMiddleware(req, res, done)
    expect(res.status).to.have.been.calledWith(401)
}).timeout(10000)

}）

摩卡测试表达异步中间件不起作用
