You might want to write and run automated tests for your systems.
You can use the regular Rust testing features (
cargo test) with Bevy.
To do this, you can create an empty ECS
World in your
tests, and then, using direct World access, insert whatever
entities and resources you need for testing. Create
a standalone stage with the systems you want to
run, and manually run it on the
Bevy's official repository has a fantastic example of how to do this.
