AI for software testing
Free prompts that decide what to test before you merge, find the case your feature prompt forgot, and name the check to run. Paste into Claude, ChatGPT, or Cursor.
Most testing trouble is not writing assertions. It is knowing which cases matter and why a test lies. These prompts work from the feature prompt, the diff, or the failing log and give you a list you can act on.
Which one to use
- 01 · Coding & Vibe CodingMediumTest Plan from the PromptPaste the prompt you used to vibe-code a feature. Get the checks to run before merge, including the case that prompt forgot.When to use itUse it right after you vibe-code a feature, when the happy path works and the cases you never mentioned are untested.When to skip itIt writes the checks, not the test code. Ask your coding agent to implement the cases once you agree with the list.
- 02 · Coding & Vibe CodingMediumDiff Risk ReviewerRead a vibe-coded diff for behavior risk: what changed, what can break, and which check to run before you push.When to use itUse it when Cursor or Claude just wrote a change you did not type yourself and you need to know which behavior moved before you push.When to skip itIt is not a style linter and it does not know your production traffic. If the diff touches payments or auth, a human reviewer still signs off.
