Announcing AI-Powered API Test Generation in Katalon Studio

It's well known that creating API test cases can be time-consuming and repetitive. Manually adjusting web service requests and verification steps is not only tedious but also prone to errors, especially when dealing with complex systems. Today, we’re thrilled to announce a game-changing feature in Katalon Studio that will revolutionize your testing workflow: AI-powered API test generation from OpenAPI/Swagger specifications.

Why this matters

We understand the pain points you face daily. The process of creating API test cases manually is not only labor-intensive but also demands a high level of attention to detail. This new feature addresses these challenges head-on by utilizing generative AI to automate the creation of API test cases. This means you can now generate accurate and relevant test cases faster, allowing you to focus on more critical aspects of your projects.


You talked, we listened

The need for a more efficient method to create API test cases is evident. In our conversations with our user community, quality engineers expressed the necessity for automation in generating API test cases, as AI can help achieve higher test coverage and speed up the process. According to the 2023 State of the API Report by Postman, 60% of respondents are already using generative AI tools, with many reporting increased productivity. This aligns perfectly with the rising demand for AI-driven solutions in API testing.

How you'll benefit from this?

In Katalon Studio, the feature for importing OpenAPI or Swagger specifications is already popular. By integrating AI capabilities into it, we aim to make the process of generating web service requests and API test cases easier, more efficient, and more accurate.

Key features

Here’s what you can expect from the AI-powered API Test Generation feature:

1. Automatic test case generation: Simply import your OpenAPI or Swagger specifications, and let the AI do the rest. It quickly generates comprehensive test cases, saving you valuable time.


2. Endpoint selection: Choose specific endpoints for which you want to generate test cases, optimizing resource usage and focusing on critical areas.


3. Selective saving: After generation, review and select which test cases you want to save, avoiding unnecessary duplicates.


4. Notifications and updates: Stay informed about new AI features through tooltips and in-app notifications.


5. Distinguish AI-generated tests: Easily identify AI-generated test cases with distinct folder names and icons, streamlining your test case management.


Whether you’re an experienced tester or a developer looking to ensure your APIs are robust before handing them off, this new feature in Katalon Studio will significantly enhance your productivity. It’s ideal for anyone familiar with API testing and OpenAPI/Swagger specifications, looking to adopt AI-powered solutions to streamline their workflow.
