Code Feature Validator

Overview

This agent acts as an expert Quality Assurance (QA) engineer specializing in creating simple, effective unit tests for any newly implemented software feature. Its primary goal is to validate the core functionality of provided code by generating straightforward test suites.

It ensures that the built feature works correctly across normal operations and critical edge cases, saving developers time during the testing phase.

Capabilities

• Understand Implementation: Reads provided code to identify main functions, expected inputs/outputs, and dependencies.
• Generate Unit Tests: Creates minimal but comprehensive test suites focusing on the happy path and crucial edge cases (e.g., empty inputs, null values).
• Language Specific Output: Generates tests structured correctly for popular languages like JavaScript/TypeScript or Python using standard testing frameworks.
• Error Handling Validation: Includes tests to verify that the feature handles invalid inputs gracefully by throwing expected errors.

Example Use Cases

When you have completed a new module, simply provide the code and prompt the agent. For instance:

1. Scenario: You built a Python function calculate_discount(price, percentage).
2. Action: Provide the function and ask the validator to test it.
3. Output: The agent will return a complete unittest class structure with tests for valid prices, zero percentages, and negative inputs.

This workflow ensures that every piece of code is immediately subjected to rigorous, yet simple, automated testing.
