Hey @Bryan-Roe - I've reviewed your changes - here's some feedback:

• The generate_missing_tests method doesn’t return the generated_count but main expects a result—add a return of generated_count so the final summary is accurate.
• The final print statement is dedented outside of the main function and will cause an indentation error—indent it properly within main.
