sastestgenerator

Minimal proof-of-concept R package for preparing SAS macro validation tests from functional requirements documents (FRDs).

Current scope

The initial package can:

1. Read text-based FRDs.
2. Import SAS macro source and extract macro names and parameters.
3. Build a structured prompt for an LLM.
4. Accept an optional generator function for an ellmer integration.

frd <- read_frd("requirements.txt")
macro <- import_sas_macro("derive_flag.sas")

result <- generate_sas_tests(frd, macro)
cat(result$prompt)

# Set OPENROUTER_API_KEY in .Renviron before calling the live model.
live_result <- generate_sas_tests_openrouter(frd, macro)
live_result$parsed

PDF/DOCX parsing and generated SAS execution are intentionally outside this first POC boundary. The OpenRouter API key is read by ellmer from the OPENROUTER_API_KEY environment variable and is never stored by the package.
