Missing Testing Features in Rust
summary
A new Rust test framework called test-r implements shared dependencies (async constructors scoped per module), a dependency matrix for generating many permutations, and dynamic test generators that act like static tests; it runs under cargo test, integrates with IDE test views (works in IntelliJ/Rust Analyzer, not VS Code), supports async tests, and is used in Golem Cloud CI. Tradeoff: output capturing, parallelism and truly global shared instances cannot all be enabled simultaneously, so the runner spawns child processes to preserve capture.
