πŸ’– unit_diff β€” the manual page, but make it slay πŸ’–

okay bestie, so this is unit_diff.1(1) from the Debian GNU System, and honestly? it's a lil baby of a manpage but it's so useful. sit down, grab a strawberry, let's go πŸ“βœ¨


🌸 NAME 🌸

unit_diff β€” a command-line filter that diffs the results you expected against the results you actually got, so you can see exactly what's wrong. no cap. πŸ”


πŸŽ€ SYNOPSIS πŸŽ€

./TestMyProject.rb | unit_diff

that's it. that's the whole vibe. you pipe your test output into it and it tells you the tea. β˜•πŸ’…


✨ DESCRIPTION ✨

unit_diff is a command-line filter that diffs expected results from actual results and lets you quickly see exactly what is wrong. it's giving "diagnostic bestie" energy β€” it doesn't run your tests, it just takes the output and shows you the receipts. πŸ§ΎπŸ’€

⚠️ heads up, queen: minitest 2.2+ provides an enhanced assert_equal that obviates the need for unit_diff. so if you're on a newer minitest, you might not even need this anymore. still iconic though. πŸ‘‘

and if you want even more details, go peek at /usr/share/doc/ruby-zentest/ β€” that's where the lore lives. πŸ“šπŸ¦‹
