Javascript 编写单元测试时createUser不是函数错误？

在编写函数的单元测试用例时，我遇到了以下错误

(0 , _service.createUser) is not a function

TypeError: (0 , _service.createUser) is not a function
    at _callee$ (https://pbz00.csb.app/src/service.test.js:43:44)
    at tryCatch (https://pbz00.csb.app/node_modules/regenerator-runtime/runtime.js:62:40)
    at Generator.invoke [as _invoke] (https://pbz00.csb.app/node_modules/regenerator-runtime/runtime.js:288:22)
    at Generator.prototype.<computed> [as next] (https://pbz00.csb.app/node_modules/regenerator-runtime/runtime.js:114:21)

我想检查它的返回值

true

或

undefined

这是我的密码

已更新

import { createUser } from "./service";
import axios from "axios";
describe("service test", () => {
  it("check abc value", async () => {
    jest.spyOn(axios, "post").mockImplementation(() =>
      Promise.resolve({
        data: {
          greeting: "hello there",
          status: {
            code: "200"
          }
        }
      })
    );
    console.log("createUser", createUser);
    let abc = await createUser();
    console.log("after createUser", abc);
    expect(abc).toBe(true);
  });
});

你把它输入错了。应该是：

从“/service”导入{createUser}；

要模拟axios模块，您可以使用：

jest
  .spyOn(axios, 'post')
  .mockImplementation(() => Promise.resolve({
     data: {
       greeting: "hello there",
       status: {
        code: "200"
       }
     }
  }))

您也可以模拟整个模块：

但它不会返回真或假..如何模拟我的请求？您知道如何检查

abc

变量值或返回值吗？这可以回答您的问题：谢谢回答。。！！请参阅更新。现在找不到axios更新代码沙盒

import { createUser } from "./service";

describe("service test", () => {
  it("check abc value", async () => {
    jest.spyOn(axios, "post").mockImplementation(() =>
      Promise.resolve({
        data: {
          greeting: "hello there",
          status: {
            code: "200"
          }
        }
      })
    );
    console.log("createUser", createUser);
    let abc = await createUser();
    console.log("after createUser", abc);
    expect(abc).toBe(true);
  });
});

import { createUser } from "./service";
import axios from "axios";
describe("service test", () => {
  it("check abc value", async () => {
    jest.spyOn(axios, "post").mockImplementation(() =>
      Promise.resolve({
        data: {
          greeting: "hello there",
          status: {
            code: "200"
          }
        }
      })
    );
    console.log("createUser", createUser);
    let abc = await createUser();
    console.log("after createUser", abc);
    expect(abc).toBe(true);
  });
});

jest
  .spyOn(axios, 'post')
  .mockImplementation(() => Promise.resolve({
     data: {
       greeting: "hello there",
       status: {
        code: "200"
       }
     }
  }))
