User Stories

User Story 1: Email Validation

As a user, I want to verify if an email address is valid so that I can ensure it can be used for registrations or communications.

Acceptance Criteria: • Valid Format: The email address must follow the standard format (e.g., [e-mail]). • Valid Domains: Domains must include a domain name and an extension (e.g., .com, .org). • Invalid Values: • An empty string or one without @ should be considered invalid. • Emails without a domain extension should be rejected.

User Story 2: Password Strength

As a user, I want to verify if a password meets security criteria to ensure my personal information is protected.

Acceptance Criteria: • Minimum Length: The password must be at least 8 characters long. • Complexity Requirements: • At least one uppercase letter. • At least one lowercase letter. • At least one digit. • At least one special character (e.g., @, !, %). • Weak Password: A password failing any of the above criteria is considered weak.

User Story 3: Phone Number Validation

As a user, I want to verify if a phone number is valid and correctly formatted to ensure it can be used for calls or SMS.

Acceptance Criteria: • International Format: The number must include a country code (e.g., +1, +33). • Regional Validity: The number must follow the specific rules of the associated region. • Invalid Values: • Empty strings or numbers without a country code should be rejected. • Numbers containing letters or non-numeric symbols should be rejected.

User Story 4: Birth Date Validation

As a user, I want to verify if a birth date is valid to ensure it is realistic and can be used in forms or identification systems.

Acceptance Criteria: • Valid Format: The date must be in the DD-MM-YYYY format. • Realistic Date: The birth date cannot be in the future. • Invalid Dates: • An empty string or a date in the wrong format (e.g., DD/MM/YYYY, YYYY-MM-DD) should be rejected. • Impossible dates (e.g., 2023-02-30) should be rejected.

User Story 5: Credit Card Validation
