The extractEmails() method scans a string and identifies all substrings that match a standard email pattern. It returns a list of email addresses found in the input text. This method is designed to be: Case-insensitive Robust for common email formats Safe (returns empty array if no matches found) All extracted emails are normalized to lowercase to ensure consistency and avoid duplicates caused by case differences.

The test provides a string containing more than one valid email address and ensures that the function returns all detected emails in the correct order as an array.
It confirms that:
Multiple email patterns within a string are correctly matched
Emails are extracted accurately without missing any valid entries
The output format is consistent (array of strings)
