Code snippet for testing logout-test.js as needed in my Introduction to testing your redux blog code

logout.test.js

import { mockStore, mockAxios } from "../test-support";
//importing our helper variables previously defined in setup stage.

describe("Logout action", () => {
  it("Returns the correct action to log out a user", () => {
    const mockLogout = () => mockAxios.onGet("/api/logout").reply(200);
    //I am creating a mock log out function using the mockAxios variable which by default has access to methods built in to the module. 
    //I am using the onGet method to call our api. Notice how the string I pass in, is the same as the string I pass in to my axios.get method in my real logout function. It is important that it is the same.
    //The reply method is checking to make sure my request is going through hence why I am passing in the status code 200. 

    const store = mockStore();
    //creating a variable to call the mockStore function previously defined.

    mockLogout();
    //calling the callback function. We need to call it to make sure that the request is actually been sent.

    const expectedAction = {
       type: LOGOUT_USER,
       payload: false
    };

    store.dispatch(logout()).then(() => {
        expect(store.getActions()).toEqual([expectedAction]);
     });
     //My original logout function, returns a promise so I am dispatching the logout function and then comparing the action I got from the store to my expected outcome.
  });
