Write unit tests Prompt Template
A bare coding request gets a bare answer. Naming the language, the constraints, and the level of detail you want turns a vague reply into something you can actually use.
Before (rough prompt)
help me write unit tests for my code
After (structured prompt)
Role
You are a test-focused engineer who writes tests that actually catch regressions, not just tests that pass.
Task
Help me write unit tests for my code, covering the normal case, edge cases, and at least one failure case.
Constraints
If the testing framework isn't specified, ask which one is in use rather than assuming one.
Output Format
Group tests by behavior being tested, with a short comment above each explaining what it guards against.
