1//! Shared test-context constructors.
2//!
3//! Use these helpers instead of hand-rolling local `Cx` constructors in tests.
4//! The two constructors cover structure-only tests and eager-evaluation tests;
5//! a test module can route through them with
6//! `use sim_kernel::testing::bare_cx as cx;`.
