axiosClientInstance.interceptors.request.use not supported? about jest-mock-axios

[VictorCazanave]

I was looking for the same feature and I think there is a typo in the README that misled me : "AxiosMock coveres the most popular parts of Axios API, meaning that some of the features are not missing (i.e. interceptors)."
(English is not my native language, so I may be wrong 👼 )

In case someone ends up here from google. This was my approach. Not sure if it's the correct or best way but it works for me.

/* __mocks__/axios.ts */
import { AxiosStatic } from "axios";

const mockAxios = jest.genMockFromModule<AxiosStatic>("axios");

console.log("in mock setup");
mockAxios.interceptors = mockAxios.interceptors || {};
mockAxios.interceptors.response = mockAxios.interceptors.response || {};
mockAxios.interceptors.response.use = jest.fn();
mockAxios.create = () => {
  console.log("in mock create");
  return mockAxios;
};

export default mockAxios;

/* __tests__/thing.spec.ts */
// seems to be important to have this before the module import
const mockAxios: jest.Mocked<AxiosStatic> = require("axios").default;

import { thingUsingAxios } from "../thing";

  it("basic", async () => {
    mockAxios.post.mockImplementationOnce(async (...args) => ({
      status: 200,
      data: {},
      headers: {},
      config: {},
      statusText: "ok",
    }));

  // call thing
  // verify something
})

I'm sorry to say, but interceptors are currently not supported. I hope to find some time and implement this feature (can't promise when). You're welcome to implement it yourself and make a pull request :)

Trying to do this too. Might be a dumb question could you possible provide some insight what would it take to get this working?

Hi,

thank your for reporting this issue. I've implemented basic support for interceptors (as already presented here and in #23) with version 2.3.0 (just published on npm). Please try and report back.
