The key similarities between test automation and test orchestration are that they both aim to automate testing processes, and they share some benefits such as reducing the effort required for engineers to run tests and increasing consistency in testing. However, test orchestration is more about coordinating multiple automated tests to run in a predefined sequence, whereas test automation focuses on automating individual software tests. Test orchestration can help save even more time and effort than test automation alone by efficiently managing complex testing scenarios. It can also eliminate the need for manual management of software testing processes, allowing teams to keep pace with software delivery operations and ensure consistent and efficient release of high-quality applications.
