description	Split inline

Always split inline #[cfg(test)] mod tests { ... } blocks into co-located _test.rs files.

What to do

For each Rust source file src/foo.rs that contains an inline test block:

1. Create src/foo_test.rs with use super::*; at the top, followed by the bare test functions (no mod tests { } wrapper)
2. In src/foo.rs, replace the inline block with:

   #[cfg(test)]
   #[path = "foo_test.rs"]
   mod tests;
   

For directory modules like src/app/mod.rs, the test file is src/app/mod_test.rs.

When to use me

Use this skill when:

• You encounter a Rust source file with #[cfg(test)] mod tests { ... } inline — immediately split it
• You create a new Rust module — immediately create its _test.rs companion
• You add tests to an existing module — append to the existing _test.rs, never inline
