/**
 * Intercepts all IPC requests with the given mock handler.

 * This function can be used when testing tauri frontend applications or when running the frontend in a Node.js context during static site generation.
 *
 * # Examples
 *
 * Testing setup using Vitest:
 * ```js
 * import { mockIPC, clearMocks } from "@tauri-apps/api/mocks"
 * import { invoke } from "@tauri-apps/api/core"
 *
 * afterEach(() => {
 *    clearMocks()
 * })
 *
 * test("mocked command", () => {
 *  mockIPC((cmd, payload) => {
 *   switch (cmd) {
 *     case "add":
 *       return (payload.a as number) + (payload.b as number);
 *     default:
 *       break;
 *     }
 *  });
 *
 *  expect(invoke('add', { a: 12, b: 15 })).resolves.toBe(27);
 * })
 * ```
 *
 * The callback function can also return a Promise:
 * ```js
 * import { mockIPC, clearMocks } from "@tauri-apps/api/mocks"
 * import { invoke } from "@tauri-apps/api/core"
 *
 * afterEach(() => {
 *    clearMocks()
 * })

 *  mockIPC((cmd, payload) => {
 *   if(cmd === "get_data") {
 *    return fetch("https://example.com/data.json")
 *      .then((response) => response.json())
 *   }
 *  });
 *
 *  expect(invoke('get_data')).resolves.toBe({ foo: 'bar' });
 * })
 * ```
