Chai-http 请求返回未定义

Chai-http request returning undefined

下面是我的代码:

server.js

const app = express();
app.listen(port, () => {
  logger.info(`App running on http://localhost:${port}`);
});

export default app;

test.js

import server from "../../src/index.js";

chai.use(chaiHttp);

describe("GET Balance API Tests", () => {
  beforeEach(() => {
    const userBalance = mockUserBalances;
  });

  it("should return correct value", async () => {
    const res = await chai.request(server).get("/balance/user-1");
    console.log(res.status);  // this correctly returns 200
    res.status.should.equal(200);  // this throws an error stating res is undefined
  });
});

我在这里做错了什么?为什么每当我尝试做任何断言时 res 总是未定义?

因为 res.status 是“200”,我认为它不会有 should 属性。我认为正确的说法应该是这样的:

expect(res).to.have.status(200);
