Hi @Samuel,

Apologies for the delayed response! This behavior is a result of the fact that we’re in the process of [deprecating the Mojo REPL](https://forum.modular.com/t/mojo-repl-deprecation/1158). Docstring tests were previously executed via the REPL. Going forward, we recommend instead [setting up a dedicated testing environment and a `test` action with Magic](https://docs.modular.com/max/tutorials/magic/#step-6-setup-a-test-environment) and using `magic run test.` We’d also recommend checking out [the Mojo standard library test files](https://github.com/modular/max/tree/main/mojo/stdlib/test) and [MAX examples](https://github.com/modular/max/tree/main/examples) for examples of how we recommend structuring tests.
