test-patterns

Write and run tests across languages and frameworks. Use when setting up test suites, writing unit/integration/E2E tests, measuring coverage, mocking dependencies, or debugging test failures. Covers Node.js (Jest/Vitest), Python (pytest), Go, Rust, and Bash.

Test Patterns

Write, run, and debug tests across languages. Covers unit tests, integration tests, E2E tests, mocking, coverage, and TDD workflows.

When to Use

Setting up a test suite for a new project
Writing unit tests for functions or modules
Writing integration tests for APIs or database interactions
Setting up code coverage measurement
Mocking external dependencies (APIs, databases, file system)
Debugging flaky or failing tests
Implementing test-driven development (TDD)

Node.js (Jest / Vitest)

Setup

# Jest
npm install -D jest
# Add to package.json: "scripts": { "test": "jest" }

# Vitest (faster, ESM-native)
npm install -D vitest
# Add to package.json: "scripts": { "test": "vitest" }

Unit Tests

// math.js
export function add(a, b) { return a + b; }
export function divide(a, b) {
  if (b === 0) throw new Error('Division by zero');
  return a / b;
}

// math.test.js
import { add, divide } from './math.js';

describe('add', () => {
  test('adds two positive numbers', () => {
    expect(add(2, 3)).toBe(5);
  });

  test('handles negative numbers', () => {
    expect(add(-1, 1)).toBe(0);
  });

  test('handles zero', () => {
    expect(add(0, 0)).toBe(0);
  });
});

describe('divide', () => {
  test('divides two numbers', () => {
    expect(divide(10, 2)).toBe(5);
  });

  test('throws on division by zero', () => {
    expect(() => divide(10, 0)).toThrow('Division by zero');
  });

  test('handles floating point', () => {
    expect(divide(1, 3)).toBeCloseTo(0.333, 3);
  });
});

Async Tests

// api.test.js
import { fetchUser } from './api.js';

test('fetches user by id', async () => {
  const user = await fetchUser('123');
  expect(user).toHaveProperty('id', '123');
  expect(user).toHaveProperty('name');
  expect(user.name).toBeTruthy();
});

test('throws on missing user', async () => {
  await expect(fetchUser('nonexistent')).rejects.toThrow('Not found');
});

```bash
# Jest

# Add to package.json: "scripts": { "test": "jest" }

# Vitest (faster, ESM-native)
npm install -D vitest

```javascript

export function divide(a, b) {
  if (b === 0) throw new Error('Division by zero');
  return a / b;

  expect(user).toHaveProperty('name');
  expect(user.name).toBeTruthy();

test('throws on missing user', async () => {
  await expect(fetchUser('nonexistent')).rejects.toThrow('Not found');
