Katalon Studio is a comprehensive automation testing tool that enhances Selenium and Appium with a complete test automation framework. It provides project templates for organizing test cases, object repository, and keywords, and fully supports Web, Android, iOS, and API testing on all operating systems. It is easy to integrate with Jenkins, GIT, JIRA, and qTest with native plugins, and records actions on Web & Mobile to generate scripts with hundreds of built-in keywords. It runs/debugs test cases or test suites using multiple configurations and data sets, and runs tests at any step on multiple browsers and devices locally or with cloud services. It includes run-time rules to automatically handle complex execution flows, with advanced logging, debug data, screenshots, and videos. It also has customizable post-execution workflows to notify, submit bugs, or process the execution results, and dashboards, flaky metrics, and coverage execution results to improve automation strategy. It allows easy management and maintenance of tests, data, and keywords, and imports external libraries to improve the automation functions beyond Selenium and Appium limit.
