//! Gated Tests
//!
//! Each gated benchmark registered by [`super::register_benchmarks`] has a "real" counterpart
//! here. When the controlling feature set is enabled in the [`super::TestConfig`], the real
//! benchmark (and its input, if it too was gated) is registered instead of the gated stub. This
//! mirrors how a downstream crate uses `cfg_if!` to swap a gated placeholder for the compiled
//! benchmark once the relevant Cargo feature is turned on.
