Setting IP Address in unit test to pass the ipRestrictions middleware

[snowfluke]

Hi, thank you for the amazing works.

I just wondering how can I set an IP Address in the app.request() in unit test using bun:test.
Because I've got an error stating that:

src/test/index.test.ts:
4 |   const server = getBunServer(c);
5 |   if (!server) {
6 |     throw new TypeError("env has to include the 2nd argument of fetch.");
7 |   }
8 |   if (typeof server.requestIP !== "function") {
9 |     throw new TypeError("server.requestIP is not a function.");
              ^
TypeError: server.requestIP is not a function.
      at getConnInfo (/home/ppu/ocr-bun/node_modules/hono/dist/adapter/bun/conninfo.js:9:11)

My test is fairly simple one:

// index.test.ts
  test("GET /", async () => {
    const res = await app.request("/", {}, MOCK_ENV);

    expect(res.status).toBe(200);
  });

// index.ts 
app.use(
  "*",
  ipRestriction(
    getConnInfo,
    {
      denyList: [],
      allowList: ["127.0.0.1", "::1", "*"]
    },
    async (remote) => {
      throw new UnauthorizedError(
        `Your IP Address (${remote.addr}) is blocked`
      );
    }
  )
);

Solve by adding server object to the mock_env and passing it as third argument in app.request():

const MOCK_ENV = {
    server: {
      requestIP: () => {
        return {
          address: '127.0.0.1',
          family: 'foo',
          port: '123'
        }
      }
    }
}

No, the error is solved but to test by setting mock ip address to test ipRestriction middleware is still unknown
