# Objective - Fixes #15319 - Fixes #15317 ## Solution - Updated CI task to check for _any_ `bevy_*` crates, rather than just `bevy_internal` --------- Co-authored-by: François Mockers <francois.mockers@vleue.com>

//! A test to confirm that `bevy` doesn't regress its system ambiguities count when using [`DefaultPlugins`].
|
|
//! This is run in CI.
|
|
//!
|
|
//! Note that because this test requires rendering, it isn't actually an integration test!
|
|
//! Instead, it's secretly an example: you can run this test manually using `cargo run --example ambiguity_detection`.
