Writing Tests

Write effective tests using Vitest and React Testing Library.

Quick Start

Create a unit test in src/common/__tests__/utils/math.test.ts:

import { describe, it, expect } from 'vitest';
import { add } from '../../utils/math';

describe('math utility', () => {
  it('adds two numbers correctly', () => {
    expect(add(1, 2)).toBe(3);
  });
});

Run tests with npm run test.

Core Patterns

Unit Testing

Focus on pure functions and logic in src/main or src/common. Use vi.mock() for dependencies.

references/unit-testing-examples.md

Component Testing

Test React components in src/renderer. Focus on user interactions and props.

references/component-testing-patterns.md

Mocking

Use centralized mock factories for consistent testing across components and contexts.
