Fixture-Driven Testing Strategy

API parity is ensured by defining test fixtures once in a canonical Rust implementation and reusing them across Python, Node.js, Ruby, and Java bindings. This validates that all language wrappers produce identical output for the same input.

Fixture-driven testing is a strategy that leverages a canonical Rust implementation to generate and consume JSON or YAML fixtures. It ensures shared codebases have consistent test behavior across multiple language bindings.

You can share test fixtures by programmatically generating them from your canonical Rust implementation into reusable formats like JSON and YAML. These shared fixture files are then consumed by all language bindings.

Yes, automated fixture generation from the canonical Rust implementation reduces test duplication. You execute a cross-language test parity script to verify consistency across all language bindings without writing separate tests.

The best way is using a canonical Rust implementation to generate shared JSON or YAML fixtures. This guarantees that Python, Node.js, and Ruby wrappers for your library all produce the exact same output for the same input.

No dependencies are required. The strategy uses scripts and references to generate JSON and YAML fixtures from a canonical Rust implementation, consuming them across Python, Node.js, Ruby, and Java bindings without extra dependencies.
