35 Test Cases for User Interface Testing
When testing user interfaces, it is easy to overlook test cases that would be helpful for a more thoroughly tested solution. The following list identifies twenty test cases that should be considered when testing user interfaces.
20 Useful Test Cases for Testing User Interfaces
- Required Fields
If the screen requires data entry on a specific field, designers should identify the required fields with a red asterisk and generate a friendly warning if the data is left blank. - Data Type Errors
If the screen contains dates, numeric, currency or other specific data types, ensure that only valid data can be entered. - Field Widths
If the screen contains text boxes that allow data entry, ensure that the width of data entered does not exceed the width of the table field (e.g. a title that is limited to 100 characters in the database should not allow more than 100 characters to be entered from the user interface). - Onscreen Instructions
Any screen that is not self-explanatory to the casual user should contain onscreen instructions that aid the user. - Keep Onscreen Instructions Brief
While onscreen instructions are great, keep the wording informative, in layman’s terms, but concise.
