chore(base.lua): refactor test result printing and cleanup

Refactor the code to extract the test result printing logic into a separate function, `print_result_line`, to improve readability and reduce code duplication. This change aims to enhance maintainability by consolidating similar print statements and ensuring consistent display of test results across the script.
