The Tasks Engineers Hate
Writing unit tests and documentation is critical for a healthy codebase, but developers notoriously hate doing it. Luckily, AI doesn't have feelings.
Because writing tests and docs is a highly patterned, predictable task, AI models excel at it.
The Unit Testing Prompt
Goal: Write a comprehensive test suite for this utility function using Jest.
Constraints:
- Include tests for standard inputs.
- Include edge cases (empty arrays, null values, extreme numbers).
- Mock any external API calls.
The JSDoc Prompt
Goal: Generate professional JSDoc comments for every function in this file.
Requirements: Include `@param` with types, `@returns`, and a brief one-sentence description of what the function actually does in business terms.
