Key Features of Katalon Studio
Unified Testing for Multiple Platforms
Execute end-to-end testing scenarios across web browsers, mobile devices (iOS & Android), desktop applications (Windows), and REST, SOAP, and GraphQL APIs from a single project. This eliminates context switching and simplifies your testing ecosystem management.
Dual-Scripting Interface
Leverage the flexibility of both codeless record-and-playback for rapid test creation and manual scripting in Groovy or Java for advanced test logic and customization. This hybrid approach maximizes team productivity and skill utilization.
Built-In AI and Self-Healing Capabilities
Utilize AI to auto-heal broken locators when application UIs change, dramatically reducing test maintenance time. Smart Wait and Visual Testing features further enhance test resilience and accuracy against flaky tests.
Comprehensive Test Management and Reporting
Organize test cases, plan test cycles, and track execution history seamlessly. Generate insightful dashboards and detailed reports with logs, screenshots, and videos to facilitate quick debugging and stakeholder communication.
Seamless CI/CD and Ecosystem Integration
Integrate directly with popular tools like Jira, Jenkins, Azure DevOps, Git, and Slack. This enables seamless test execution within your DevOps pipeline for true continuous testing and faster release cycles.
