React app testing, how to test an axios post request with Jest?

Question

App.js looks like this, how would I test it with jest?

 

    handleClick = e => {
        axios
          .post(
            "https://api.openweathermap.org/data/2.5/weather?q=" +
              this.state.term +
              "&units=metric&appid=" +
              ApiKey
             
          ){...}

I know I have to create a mocking axios file and then test it like that, but it uses setState in the main App.js. I just want to test the fetch request/axios post with jest.

Just return promise of axios code check below code snippet

    // apiActions.js
    const axios = require('axios');
    
    // your api code goes here
    const fetchData = () => {
      return axios
        .get('https://jsonplaceholder.typicode.com/sample_url')
        .then(response => {
          return response.data;
        });
    };

    exports.fetchData = fetchData;

    // testSuit.js
    import fetchData from './apiActions.js';
    // your testing code goes here
    test('testing api call', () => {
    const sampleObj = {name:'',age:39....}
    fetchData().then(resp => {
      expect(resp).toMatchObject(sampleObj)
    })

Thanks for responding. In the testSuit.js, the fetchData is returning undefined, but in the apiActions.js the fetchData is assigned but it's value is never read? – Rian Coetzee Jan 28 '22 at 07:00
@RianCoetzee do you want to test the post call or get call.? – Ramusesan Jan 28 '22 at 07:43
