In my application, I am utilizing the Google Maps JS API for autocompletion and geocoding. To load the API, I am using the Google Maps JS API Loader package from NPM. During end-to-end testing with Cypress, I attempted to mock the API for testing purposes but encountered challenges in making it functional.
I have abstracted the API functionality into a separate module. Here is a simplified version of how it is loaded and initialized:
import {Loader} from "@googlemaps/js-api-loader";
let loading: Promise<typeof google>;
try {
loading = new Loader({
apiKey: "private key",
libraries: ["places"],
}).load();
} catch (e) {
console.error("Failed to load Google Maps API");
}
class GoogleMapsAPI {
// Class implementation details here...
}
async function loadGoogleMapsAPI(): Promise<GoogleMapsAPI | null> {
// Load logic here...
}
This is how the API is integrated into my React app:
import React, {useEffect, useState} from "react";
import {GoogleMapsAPI, loadGoogleMapsAPI} from "../../services/google";
export default function Site() {
// React component code here...
}
When attempting to test the functionality, I encountered difficulties related to stubbing out the necessary methods for proper test execution. Despite various attempts, the desired predictions were not being returned as expected.
As I navigate through this testing process with Cypress and frontend code, I seek guidance on effectively handling stubbing and ensuring the correct functioning of the mocked API. Any assistance or insights would be greatly appreciated!
