//! Integration coverage for the client window layout contract.
|
|
//!
|
|
//! Scope: exercise `layout::apply` end-to-end against a fake `swaymsg` binary.
|
|
//! Targets: `client/src/layout.rs`.
|
|
//! Why: this keeps layout policy coverage centralized in `testing/tests` while
|
|
//! avoiding source-LOC ratchet growth in the client crate.
