This function creates FreshContext which can be passed directly to fresh handlers, middlewares, routes, etc. If CreateFreshContextOptions.manifest is specified, FreshContext.params and a route to be rendered by FreshContext.render is automatically inferred from Request.url.

import { createFreshContext } from "$fresh-testing-library/server.ts";
import { handler } from "$/routes/api/users/[id].ts";
import manifest from "$/fresh.gen.ts";
import { assertExists } from "$std/assert/assert_exists.ts";
import { assertEquals } from "$std/assert/assert_equals.ts";

const request = new Request("http://localhost:8000/api/users/34");
const ctx = createFreshContext(request, { manifest });
assertEquals(ctx.params, { id: "34" });

assertExists(handler.GET);
const response = await handler.GET(request, ctx);
