Format and field rules
A split form normally places 1846 Cedar Avenue on Line 1 and Apt 4B on Line 2. A single-line address can append the unit after the street.
Do not place the apartment number in City or ZIP Code. Automation should map values to the form model instead of pasting one complete address everywhere.
Recommended test cases
Cover normal input, boundary input, and deliberately invalid input as separate cases.
- Test Apt, Unit, and Suite labels
- Cover an alphanumeric unit such as 4B
- Check the Line 2 length limit
Scope
This guide explains development-test formatting. It does not provide a delivery, identity, or payment verification result.
