# Description Was original asked here: https://github.com/nushell/nushell/pull/8405#issuecomment-1465062652 Make it easier to extend standard library with submodules. (For a new submodule called `xx.nu` the tests can be written in `test_xx.nu`). Test discovery is implemented. # User-Facing Changes There are no user-facing changes. # Tests + Formatting Tests are updated. There is no `nufmt` now. --------- Co-authored-by: Mate Farkas <Mate.Farkas@oneidentity.com>
