Master StudioAssist: A quick guide to summarizing and explaining code in Katalon Studio


As a software testing professional, you know that efficiency is key. Whether you're reviewing your team's code or trying to understand complex test scripts, having a tool that simplifies these tasks can be a game-changer. Enter StudioAssist, an invaluable feature in Katalon Studio that can help you summarize and explain code easily. In this guide, we'll walk you through two essential use cases: generating a code summary and explaining your web test script. Let’s get started.

Code Summary: Quickly Understand Your Code

Imagine you're reviewing a colleague's code and want to get a quick overview before diving into the details. Or maybe you need to write a concise summary but are pressed for time. StudioAssist’s "Explain code" feature can handle this in just a few seconds.

Here’s how you can do it:

Step 1: Prompt Setup: 
Above your script, add the prompt, for example: Provide a summary of what this piece of code does, in 3 sentences.


Step 2: Highlight and Right-Click

Highlight the prompt, right-click, and select StudioAssist > Explain code.


Step 3: Review the Summary

StudioAssist will generate a summary like this: 


For a more detailed explanation, you can simply select the code and choose Explain code. This time, StudioAssist will break down the code line by line:
