<h2 id="example-and-usage">Example and usage</h2><p>
The below script executes a GET request on the Wikipedia homepage, checks whether the HTTP status code is 200 and if we are using the HTTP/2 protocol.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p>import http from "k6/http";
import { check } from "k6";

export default function() {
  check(http.get("https://www.wikipedia.org/"), {
    "status is 200": (r) => r.status == 200,
    "protocol is HTTP/2": (r) => r.proto == "HTTP/2.0",
  });
}
<p>The above test case can be run with the command $ k6 run http_2.js where http_2.js is the filename in which the test case is saved in.
