Mocha test express async middleware done not working

I'm trying to test an async middleware auth function using the done function of Mocha. However, it seems that the test completes before the done function is called in the async call. Isn't the test supposed to wait until the done callback is called?

The middlware:

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()
        }
    })
}

My test:

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)
})

You are treating done() as next(). Done is used to end the test while next is used in your middle ware

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)

})
