【问题描述】:
我的测试正常通过,但我不断收到 UnhandledPromiseRejectionWarning。关于如何解决这个问题的任何想法? 我尝试了很多解决方案,但似乎都没有。
node:32535) UnhandledPromiseRejectionWarning: Error: expect(received).toMatchObject(expected)
Matcher error: received value must be a non-null object
Received has value: undefined (node:32535) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:32535) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
这是我的测试文件:
jest.mock("./http");
const { fetchAllUsersData } = require("./http");
test("Data returned from server should be a list of users ", async () => {
fetchAllUsersData()
.catch((errorMessage) => expect(errorMessage).toThrowError(Error))
.then((usersRetrieved) => {
let users = usersRetrieved[0];
let userModel = {
id: 1,
first_name: "Peggy",
last_name: "Poppins",
email: "mpoppins0@squidoo.com",
ip_address: "192.54.212.191",
latitude: 34.003135,
longitude: -117.7228641222,
};
expect(users).toMatchObject(userModel);
});
});
这是我在 mock 文件夹中的文件:
const fetchAllUsersData = () => {
return Promise.resolve({
data: [
{
id: 1,
first_name: "Merry",
last_name: "Poppins",
email: "mpoppins0@squidoo.com",
ip_address: "192.54.212.191",
latitude: 34.003135,
longitude: -117.7228641,
},
{
id: 15,
first_name: "George",
last_name: "Foreman",
email: "gforeman@clear.com",
ip_address: "12.564.124.521",
latitude: 23.592254,
longitude: 125.454227,
},
],
});
};
exports.fetchAllUsersData = fetchAllUsersData;
