Marathonlabs

At MarathonLabs, we offer Marathon Cloud — a cloud testing infrastructure built on the Marathon test runner. It automatically provisions virtual devices to run your tests within 15 minutes. Test execution is delegated to the Marathon test runner, which manages batching, sorting, preventive retries, and post-factum retries for even distribution across the provisioned devices. Marathon is a fast, platform-independent test runner focused on performance and stability. It offers easy to use platform implementations for Android and iOS as well as an API for use with custom hardware farms and more techstacks. Marathon implements multiple key concepts of test execution such as test batching, device pools, test sharding, test sorting, preventive retries as well as post-factum retries. By default, most of these are set to conservative defaults but custom configurations are encouraged for those who want to optimize performance and/or stability. Marathon's primary focus is on full control over the balance between stability of test execution, testing performance and cost.
