What is the best method for testing routes implemented with the application router in NextJS? My go-to testing tool for this is vitest

Is it possible to test routes with vitest on Next.js version 14.1.0? I have been unable to find any information on this topic.

I am looking for suggestions on how to implement these tests in my project, similar to the way I did with Jest and React Router in previous projects.

Answer №1

When discussing routes in terms of route handlers, one option is to utilize the node-mocks-http package for testing purposes. This package allows you to simulate a request sent to an endpoint. Here's an example:

// @vitest-environment node

import { expect, test } from "vitest";
import { createRequest } from "node-mocks-http";

import { GET } from "app/api/users/route";

test("User endpoint works as expected", async () => {
  const source = "/tests/login.test.ts";

  const nextUrl = new URL(source, process.env.HOST);
  const request = createRequest({ method: "GET", url: "/api/users" });
  const response = await GET({ ...request, nextUrl } as any);

  expect(response.status).toBe(200);
  // ...
});

In the above test code snippet, we demonstrate creating a simulated HTTP request and passing it directly to the route handler function without the need for an actual HTTP request.
