Testing Guidelines

Learn about our testing strategies and quality assurance processes.

Testing Philosophy

Our testing approach follows the testing pyramid:

1. Unit Tests (70%)
2. Integration Tests (20%)
3. E2E Tests (10%)

Unit Testing

Component Testing

import { render, screen } from '@testing-library/react';
import { Button } from './Button';

test('renders button with text', () => {
  render(<Button>Click me</Button>);
  expect(screen.getByText('Click me')).toBeInTheDocument();
});

Hook Testing

import { renderHook, act } from '@testing-library/react-hooks';
import useCounter from './useCounter';

test('increments counter', () => {
  const { result } = renderHook(() => useCounter());
  act(() => {
    result.current.increment();
  });
  expect(result.current.count).toBe(1);
});

Integration Testing

API Testing

describe('UserAPI', () => {
  it('fetches user data', async () => {
    const user = await UserAPI.getUser(1);
    expect(user).toEqual({
      id: 1,
      name: 'John Doe'
    });
  });
});

E2E Testing

Cypress Tests

describe('Login Flow', () => {
  it('successfully logs in', () => {
    cy.visit('/login');
    cy.get('[data-testid="email"]').type('user@example.com');
    cy.get('[data-testid="password"]').type('password123');
    cy.get('[data-testid="submit"]').click();
    cy.url().should('include', '/dashboard');
  });
});
