The Manta Testautomation for Radio Access Network (RAN) project aims to deliver end-to-end device testing for 4G and 5G RAN environments, focusing on automated regression testing with various RAN vendors.

The Mobile RAN Testcase Automation (MANTA) solution is designed to efficiently execute automated regression tests whenever new software, features, or hardware changes are introduced in the RAN network. All test cases and code are managed in the Magenta CI/CD infrastructure.Test execution is driven by GitLab pipeline runners, which trigger testcase jobs either on OMCs and Radio Nodes via CLI commands or on the Test Automation Framework (TAF) platform for comprehensive User Equipment (UE) performance tests. This approach ensures repeatability, scalability, and integration into modern DevOps workflows.

Through high automation, MANTA supports rapid validation cycles, improving deployment quality and operational efficiency. The project enables seamless collaboration with RAN vendors to ensure robust, future-proof mobile network deployments.
