Marathon

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 is a project that helps execute tests in the shortest time possible. Specifically it helps with stability of test execution adjusting for flakiness in the environment and in the tests and also achieves best performance using high parallelization

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.
