Tosca is a test automation tool developed by Tricentis, a software testing company. It is designed to help teams automate end-to-end testing for web, mobile, and desktop applications.

Tosca uses a model-based approach to testing, which means that tests are created by modeling the behavior of the application under test. This allows for easier test creation and maintenance, as changes to the model can be automatically propagated to the tests.

Tosca also includes features for test data management, test execution, and test reporting. It integrates with other tools in the software development lifecycle, such as Jira and Jenkins, to provide a comprehensive testing solution.

Overall, Tosca aims to improve the efficiency and effectiveness of software testing by reducing the time and effort required to create and maintain test cases, and by providing detailed insights into application quality and performance.
