testing-conventions 0.0.49

//! Integration tests for the `functions` and `branch` floors on the Rust
//! coverage config (#267): both keys are part of the `[rust].coverage` schema,
//! accepted by the loader's self-guard alongside `regions` and `lines`.
//!
//! Red until the floors land: today the config self-guard
//! (`deny_unknown_fields`) rejects both keys, so loading these configs errors
//! instead of parsing.
