# Unit Test Generator Generate unit tests for: **$ARGUMENTS** (framework defaults to vitest) ## Steps 1. **Read the target code** — Understand the function/class signature, dependencies, return types, and side effects. 2. **Identify test cases** — For each public function or method: - **Happy path** — expected inputs produce expected outputs - **Edge cases** — empty inputs, boundary values, null/undefined - **Error cases** — invalid inputs, thrown exceptions - **Type boundaries** — test with types at the edges of what's accepted 3. **Design mocks** — Identify external dependencies: - Database calls → mock the Prisma client - API calls → mock fetch/axios - File system → mock fs - Time-dependent → mock Date.now / timers - Only mock what's necessary — prefer real implementations when possible 4. **Write tests** — Follow this structure: ```typescript import { describe, it, expect, vi } from "vitest"; import { targetFunction } from "./target"; describe("targetFunction", () => { // Group by behavior, not by method describe("when given valid input", () => { it("returns the expected result", () => { const result = targetFunction("valid"); expect(result).toEqual(expected); }); }); describe("when given invalid input", () => { it("throws a ValidationError", () => { expect(() => targetFunction("")).toThrow(ValidationError); }); }); describe("edge cases", () => { it("handles empty arrays", () => {
