Test-driven development implementation translates a behavioral specification into working code by reading the spec, existing source, and tests, then generating code that passes those tests. It enforces the RED-GREEN workflow's third step to ensure functional style and strict type discipline.

The RED-GREEN workflow for TypeScript pipeline implementation is a test-driven process where tests are written first, followed by source code implementation. This step specifically handles the third phase, replacing 'Not implemented' stubs with functional code guided by the spec and test constraints.

Generating functional TypeScript code that passes existing tests requires carefully reading the behavioral spec, source contracts, and dependencies. The process enforces a non-invasive, code-only implementation approach, ensuring strict type discipline and functional programming principles are met.

Yes, existing tests and a behavioral spec are required before code implementation begins. The process strictly prevents implementation until tests are ready and the spec exists, requiring a status update to implementing before replacing stubs with working code.

Enforcing strict type discipline during spec-driven implementation is achieved by applying a non-invasive, code-only process that reads source contracts and dependencies thoroughly. This ensures the generated TypeScript code satisfies both the behavioral specification and functional programming requirements.

Test-driven spec implementation prevents coding before tests are ready to enforce a disciplined RED-GREEN workflow. This ensures the final code strictly aligns with the behavioral specification and passes all existing tests without invasive modifications to the source.
