Hi mstoykov,
I try to do load testing with k6, but I meet below issues I want to confirm with you, I am not sure it is whether is bug or design, could you help me to answer it? thanks.
I write two request, one is get request and another one is post request, as below code,
Script output displays “http_req_failed” is 25 % failed rate,
My question1 : I just has one VUS and two api request, and why it is actually has 4 http_reqs, and has 25% failed rate. Note: script run successfully.
question 2: Will the K6 code default to multiple attempts until the request succeeds when the request fails?
question 3: Why is it that there are actually four requests when two requests are written in the code? My virtual user is 1.
import http from "k6/http";
import { check, sleep, fail } from "k6";
import { Rate, Trend, Counter } from "k6/metrics";
let username = "username";
username = encodeURIComponent(username);
let password = "password";
password = encodeURIComponent(password);
const credentials = `${username}:${password}`;
let response;
export default function () {
response = http.get(
`hide here`,
{
auth: "ntlm",
}
);
check(response, {
"0. check the get site api was 200": (res) => res.status == 200,
});
if (response.status != 200) {
console.log("error: message: sites get response not 200" + response.status);
}
response = http.post(
`url-> because of security, so I hide here',
{
headers: {
accept: "application/json, text/plain, */*",
"content-type": "application/json",
"sec-ch-ua":
'" Not A;Brand";v="99", "Chromium";v="102", "Microsoft Edge";v="102"',
"sec-ch-ua-mobile": "?0",
"sec-ch-ua-platform": '"Windows"',
auth: "ntlm",
},
}
);
// sleep(2.9);
check(response, {
"1. check the post issues api was 200": (res) => res.status == 200,
});
//console.log(response.body + response.status);
if (response.status != 200) {
console.log("post issues api not 200" + response.status);
}
}
console output:
