Mock and read search parameters (for testing React)

mockSearchParams.ts

export const mockSearchParams = (params: Record<string, string>) => {
  const baseURL = window.location.href.split(/[?#]/)[0];
  const formattedParams = Object.entries(params)
    .map(([key, value]) => `${key}=${value}`)
    .join('&');
  window.history.replaceState(null, '', formattedParams ? `${baseURL}?${formattedParams}` : baseURL);
};

export const getSearchParam = (key: string) => new URLSearchParams(window.location.search).get(key);
