🔍 Writing and Executing Tests

Example Jest Test

const request = require('supertest');
const app = require('../src/app');

describe('API endpoint tests', () => {
  test('GET /api should return status 200', async () => {
    const response = await request(app).get('/api');
    expect(response.statusCode).toBe(200);
  });
});

🎯 Best Practices

• Modularity: Structure tests clearly to enhance readability and maintenance.
• Isolation: Use mocking to isolate tests from external dependencies.
• Clear Descriptions: Provide meaningful test case descriptions for easier debugging.
• Regular Testing: Automate test runs to detect and resolve issues promptly.
