Arunika is the K6 prebuilt script to do the integration test from json file. So you don't need to create one by one test script in Javascript. That's take a lot of time my brother! Start build the json file then run it with K6.
Make sure you have installed the K6. For anyone who don't know about how to install K6, check their official documentation
I'm working on the documentation, for now, you can check the example/dummy.json as an guide. The point is, you just need to fill what inside the dummy.json with your own needs.
If you have done the json file, run it by this command
k6 run -e SCENARIO_PATH=path/to/your.json run.js
or if you want to add more log, just add --http-debug="full" after the run.js, so it become
k6 run -e SCENARIO_PATH=path/to/your.json run.js --http-debug="full"
or if you want to use the run.sh you can use
./run.sh path/to/your.json
