The article demonstrates extracting test runner logic from the main program block into callable procedures, separating result collection from output generation, and introducing a test_results_t type to encapsulate test execution data. Key improvements include making run_test_suites a pure function that returns results, creating a separate handle_test_results subroutine for output, and tracking passed/failed/total test counts. ## Full article daily.dev links to this article rather than hosting it.
