Currently we support Windows 10 and Windows 8.1. Support for Mac OS is very near.
Currently we support Chrome, Firefox, IE11. Support for Safari and Edge is very near.
Outomated is designed to be the single source of truth for all your e2e tests. Outomated keeps the source code, run history, screenshots, previews and all debug information that are always available. Since e2e tests are different from unit tests and don't test implementation paths but the expected behavior, in our opinion it is ok to keep them separately.
Not yet, but should be available in 8 to 10 months.
