Spec-first test generation creates failing tests directly from written specifications before coding, capturing intent and reducing ambiguity. This workflow ensures tests validate intended behavior rather than overfitting to existing implementations.

Mutation testing evaluates test quality by modifying code to see if tests catch the changes. It guides improvement through five anti-pattern safeguards and generation patterns, ensuring assertions meaningfully validate behavior and preventing weak suites.

Assertion quality review evaluates and refines test assertions to ensure they meaningfully validate behavior rather than just achieving coverage. This process highlights weak assertions and applies structured guidance to improve test robustness across your suite.

Yes, spec-first testing applies directly to advocacy software with domain-focused checks for privacy constraints and safety guardrails. The workflow includes five generation patterns tailored to capture advocacy-specific behavior requirements.

The five generation patterns include implementation-first, spec-first, edge-case generation, characterization tests, and mutation-guided improvement. These patterns provide structured workflow guidance for writing, reviewing, and improving tests across different scenarios.

Use spec-first testing when you need to reduce ambiguity and prevent overfitting to existing implementations. Implementation-first suits legacy code characterization, while spec-first captures intended behavior before coding begins.
