TEST AUTHORING

The test IDE built for the AI era.

Build and maintain tests faster with Al Agent, No-code, and Full-code modes - all inside Katalon Studio, included with Katalon True Platform.

AI Agent
No code
Full code

AI Agent connects to built‑in and custom MCP servers (Jira, ADO, Notion, Asana, etc.) to auto-generate test cases, objects, and test data, while also handling debugging and ongoing execution maintenance.

AI recorders for web, mobile, and desktop turn manual runs into execution‑ready test cases in minutes, making it easy for anyone on the team to create reliable tests.

Write the full code for your tests, or just custom logic to handle complex scenarios. With or without an AI coding assistance. You're in full control.

Frequently asked questions

What is Katalon Studio?

Katalon Studio is the test-automation IDE of the Katalon True Platform for authoring, debugging, and maintaining automated tests for web, mobile, API, and desktop applications. It is the authoring surface of the Katalon True Platform, so Studio artifacts become available to Platform services when you connect.

How does AI work in Katalon Studio?

Studio uses AI to speed authoring and reduce maintenance: AI agents and local agent servers can generate and maintain tests and objects; a natural-language assistant turns plain English into test scripts or explains failures; AI recorders convert real user flows into execution-ready tests; and in-IDE intelligence (visual checks, flakiness detection, self-healing locators, smart waits, and root-cause hints) keeps suites reliable.

What types of applications can I test from Katalon Studio?

You can author tests for modern web apps (SPAs and legacy pages), mobile apps (iOS and Android — native, hybrid, webviews), REST/SOAP/GraphQL APIs, and supported desktop applications. All test types are created and managed from the same Studio workspace.

What are Agent mode, No code, and Full code in Studio?

Agent mode lets AI agents, powered by MCP servers, generate and maintain tests, test objects, and data in Katalon Studio. They can debug failures and connect to tools like Jira, ADO, Notion, and Asana so your tests stay in sync with your delivery workflow.
No code uses AI web, mobile, and desktop recorders to transform manual runs into automated, execution‑ready test cases, making it easy for anyone on the team to create reliable tests.
Full code gives you full scripting flexibility with AI‑assisted coding for complex logic, custom libraries, integrations, and advanced frameworks.

Is Katalon Studio suitable for beginners and non‑coders?

Yes. Studio is designed for teams of mixed skill levels. Non‑technical users can rely on Agent mode and no‑code recorders, while Ask mode explains scripts, suggests fixes, and helps new users learn as they go. Advanced users can still drop into code at any time.

Where can I run tests I author in Studio?

Run and debug tests interactively in Studio. For larger or automated runs, the same authored tests can be executed in CI/CD pipelines or on Platform-managed cloud execution. The test files you author are preserved across these options, so you do not need to rework tests to scale.

Can I run tests locally, in the cloud, and in CI/CD?

Yes. You can:

Run and debug tests locally in Katalon Studio.
Scale execution across cloud browsers, OSs, and mobile devices with TestCloud.
Run headless or distributed executions on‑prem or in your own cloud using Runtime Engine.
Plug into CI/CD systems like Jenkins, GitHub Actions, GitLab CI, Azure DevOps, and others.

Where are my projects and how does Katalon Studio support collaboration and governance?

Studio projects live where you choose: locally, in Git, or on shared storage. Studio supports team collaboration through shared libraries, object repositories, and branch-based development. The Platform adds enterprise governance features — SSO, role-based access control, audit logs, and configurable retention — while your project ownership and files remain under your control unless you opt to sync them.
