Testing Strategy

When to use this skill

• Building core business logic (e.g., "Calculate Group Discount").
• Before major refactors.

Tools

• Vitest: Fast, Vite-compatible runner.
• React Testing Library: For component testing (optional/high-priority items only).

Example Test

import { calculatePrice } from './pricing';
import { expect, test } from 'vitest';

test('applies 10% discount for groups > 5', () => {
    expect(calculatePrice(100, 6)).toBe(540); 
});

Instructions

• Focus: Test logic, not the UI (avoid testing that "a button is blue").
• Mocks: Mock Appwrite SDK calls locally to avoid hitting the live API during tests.
