Given this test code snippet, what will be the output when the test runs?
import { render, screen } from '@testing-library/react';
import { MemoryRouter } from 'react-router-dom';
import UserProfile from '~/components/UserProfile';

test('shows user name after loading', () => {
  render();
  const nameElement = screen.getByText(/loading/i);
  expect(nameElement).toBeInTheDocument();
});
ATest passes because 'loading' text is found
BTest fails because 'loading' text is not found
CTest throws a syntax error
DTest fails due to missing MemoryRouter
Step-by-Step Solution
Solution:
  1. Step 1: Analyze render and query

    The component is rendered inside MemoryRouter, so routing context is correct. The test looks for text matching 'loading' ignoring case.
  2. Step 2: Understand UserProfile behavior

    Typically, UserProfile shows 'loading' text initially before user data loads, so the text should be present immediately.
  3. Final Answer:

    Test passes because 'loading' text is found -> Option A
  4. Quick Check:

    Loading text present = test passes [OK]
Quick Trick: Look for initial UI states like 'loading' in tests [OK]
Common Mistakes:
MISTAKES
  • Assuming user name appears immediately
  • Forgetting to wrap in MemoryRouter
  • Confusing syntax errors with runtime failures
