Tools and requirements

• Manual Evaluation

Test procedure

During manual evaluation, when testing any form inputs that have formatting requirements (like an email address space), purposely fill out the field improperly (for instance, leave the '@' symbol out of the email field). The error message for any field that has formatting requirements must describe how to properly format the data.

Inputs that may have formatting requirements may include

• Dates (mm/dd/yyyy, mm/dd/yy etc.)
• Email
• Needing NetID@cornell.edu or just NetID
• Phone Number

(For details on valid error messages, refer to Guideline 78: Whenever an input error is detected through validation, the user is informed of the error, and what was incorrect in the input.)
