In this article, I shall demonstrate a simple way we can integrate k6 with XRAY/Jira.
Sometime back I was assigned a task to write a performance test for an API that was expected to handle quite several requests. For this reason, we needed a good tool which would be faster to pick up and easier for any QA engineer to contribute.
Having used load impact in the past, I was quite familiar with K6. These are the main reasons why we chose k6 over the other performance testing tools:
Uses Javascript: Most of the QA/Developers in my team were familiar with javascript, therefore, this made it easier to pick up as there was no need to learn a new language
Open-source: This means, no payments are required to use the tool, and the community is very active.
CI/CD: Integrating k6 with our CI/CD pipelines was straightforward
I can continue discussing the advantages of choosing K6, but I will write a new post specifically about that.
After completing our test framework, we wanted our test results on Jira. Since we were already using XRAY, we needed a solution to convert the k6 JSON report to x-ray format. I couldn't get any solution that worked with our case at that time, So I had to come up with a solution. k6 made it easy by allowing me to get all metrics after the test lifecycle through the handleSummary() function, I only needed to pass the object to my implemented script and convert it to any desired format. But first, let me describe briefly the handleSummary() function.
K6 handleSummary()
This is a function in K6 used to generate custom summary reports after a load test has been completed. This function allows you to define how the summary data should be formatted and where it should be saved.
This is an essential feature that can be used to get all the metrics with different options. These options are stdout, XML, and JSON.
For this, we only needed to create a script to take in the data object from the handleSummary function.
Below is the script to convert the data object from k6 to a simple XRAY format report:
How to Setup the generator Helper Script for k6 and Xray Integration
Clone the repo to your desired location:
Preferably, create a folder inside the main project.
Example:
helper, src, report
This will help you manage the imports well without issues:
Prerequisites
Before you begin, ensure you have the following installed on your machine:
Usage
If your k6 tests are organized in groups, and each group title corresponds to a test case on Xray, you can use the generator script to create a JSON file compatible with Xray.
Example
The image below from Xray docs shows test cases with keys CALC-01 and CALC-02.
In your k6 test script, you can name the group titles as CALC-01 and CALC-02. The script will search for these group names and assign the test results to the respective test cases on Xray.
group('CALC-01', function() {
// test code
});
group('CALC-02', function() {
// test code
});
Output
The script generates a JSON file compatible with Xray, saved in the same directory as the script.
Clone the repo
git clone https://github.com/skingori/k6-json-xray.git
How to Setup the Script
We will use the handleSummary function provided by k6 and textSummary from our generator.js script to generate the JSON file. The handleSummary function takes in a data object, which we pass to getSummary to modify into an Xray-compatible format.

Change open your execution script and add the following lines:
import { getSummary } from "./generator.js";
import { textSummary } from "https://jslib.k6.io/k6-summary/0.0.1/index.js";
I am using the ./generator.js directly as it was in the same folder as my script. Let's assume you were using helper this should be:
import { getSummary } from "./helper/generator.js";
Add the end of your code adds the handleSummary function:
export function handleSummary(data) {
return {
stdout: textSummary(data, { indent: " ", enableColors: true }),
"summary.json": JSON.stringify(getSummary(data, "CALC-2062", "CALC"), null, 2)
};
}
Our function getSummary will convert the data object to x-ray format and save the output to summary.json file
Why are we using textSummary?
To have a printed output on the console, we need to import textSummary from k6 JS utility library
But this may not apply to everyone if you don't need any stdout report, you don't have to import the textSummary
Example
import http from 'k6/http';
import { sleep, group, check } from 'k6';
import { getSummary } from "./generator.js";
import { textSummary } from "https://jslib.k6.io/k6-summary/0.0.1/index.js";
export const options = {
vus: 10,
duration: '30s',
};
export default function() {
group('CALC-01', function() {
const resp = http.get('http://test.k6.io');
check(resp, {
'status is 200': (r) => r.status === 200,
});
sleep(1);
});
group('CALC-02', function() {
const resp = http.get('http://test.k6.io');
check(resp, {
'status is 200': (r) => r.status === 200,
});
sleep(1);
});
};
export function handleSummary(data) {
return {
stdout: textSummary(data, { indent: " ", enableColors: true }),
"summary.json": JSON.stringify(getSummary(data, "CALC-2062", "CALC"), null, 2)
};
}
Note: You can eliminate
stdout: textSummary(data, { indent: " ", enableColors: true }),line if you don't want to importtextSummary
handleSummaryworks by default and it's usually called at the end of the test lifecycle.
Running the Script
To run the script, use the following command:
k6 run script.js -e TEST_PLAN_KEY="CALC-2345" -e TEST_EXEC_KEY="CALC-0009"
The TEST_PLAN_KEY and TEST_EXEC_KEY are used to identify the test plan and test execution on Xray.

Output
The above script will produce the following report under summary.json
{
"info": {
"summary": "K6 Test execution - Mon Sep 09 2024 21:20:16 GMT+0300 (EAT)",
"description": "This is a k6 test with a maximum iteration duration of 4.95s, 198 passed requests and 0 failures on checks",
"user": "k6-user",

"finishDate": "2024-09-09T18:20:16.000Z",

},
"testExecutionKey": "CALC-0009",
"tests": [
{
"testKey": "CALC-01",

"status": "PASSED"
}
]
}
