It returns an empty array when no email addresses are found @test
It extracts emails from text with mixed content (URLs, emails, regular text) @test

test('extracts a single email address', () => {
  const text = 'Contact me at john.doe@example.com for more information.';
  const result = extractEmails(text);
  expect(result).toEqual(['mailto:john.doe@example.com']);
});

Extract multiple emails @test

const { extractEmails } = require('../src/email-extractor');

test('extracts multiple email addresses', () => {
  const text = 'You can reach us at support@company.org or sales@company.org';
  const result = extractEmails(text);
  expect(result).toEqual(['mailto:support@company.org', 'mailto:sales@company.org']);
});

No emails found @test

const { extractEmails } = require('../src/email-extractor');

test('returns empty array when no emails found', () => {
  const text = 'This text has no email addresses, just a website: example.com';
  const result = extractEmails(text);
  expect(result).toEqual([]);
});

Mixed content @test

const { extractEmails } = require('../src/email-extractor');

test('extracts emails from text with mixed content', () => {
  const text = 'Visit https://example.com or email admin@example.com and support@test.org';
  const result = extractEmails(text);
  expect(result).toEqual(['mailto:admin@example.com', 'mailto:support@test.org']);
});
