Aesthetic Conditions:

otherwise specified.
Is all the micro-help text spelt correctly on this screen?
Is all the error message text spelt correctly on this screen?
Is all user input captured in UPPER case or lowercase consistently?
Where the database requires a value (other than null) then this
should be defaulted into fields. The user must either enter an
alternative valid value or leave the default value intact.
Assure that all windows have a consistent look and feel.
Assure that all dialog boxes have a consistent look and feel.
Validation Conditions:
Does a failure of validation on every field cause a sensible user
error message?
Is the user required to fix entries, which have failed validation
tests?
Have any fields got multiple validation rules and if so are all rules
being applied?
If the user enters an invalid value and clicks on the OK button (i.e.
does not TAB off the field) is the invalid entry identified and
highlighted correctly with an error message?
Is validation consistently applied at screen level unless
specifically required at field level?
For all numeric fields check whether negative numbers can and should
be able to be entered.
For all numeric fields check the minimum and maximum values and also
some mid-range values allowable?
For all character/alphanumeric fields check the field to ensure that
there is a character limit specified and that this limit is exactly
correct for the specified database size?
Do all mandatory fields require user input?
If any of the database columns don't allow null values then the
corresponding screen fields must be mandatory. (If any field, which
initially was mandatory, has become optional then check whether null
values are allowed in this field.)
Navigation Conditions:
Can the screen be accessed correctly from the menu?
Can the screen be accessed correctly from the toolbar?
Can the screen be accessed correctly by double clicking on a list
control on the previous screen?
Can all screens accessible via buttons on this screen be accessed
correctly?
Can all screens accessible by double clicking on a list control be
accessed correctly?
Is the screen modal? (i.e.) Is the user prevented from accessing
other functions when this screen is active and is this correct?
Can a number of instances of this screen be opened at the same time
and is this correct?
Usability Conditions:
Are all the dropdowns on this screen sorted correctly? Alphabetic
sorting is the default unless otherwise specified.
Is all date entry required in the correct format?
Have all pushbuttons on the screen been given appropriate Shortcut
keys?
Do the Shortcut keys work correctly?
Have the menu options that apply to your screen got fast keys
associated and should they have?
Does the Tab Order specified on the screen go in sequence from Top
Left to bottom right? This is the default unless otherwise specified.
Are all read-only fields avoided in the TAB sequence?
Are all disabled fields avoided in the TAB sequence?
Can the cursor be placed in the microhelp text box by clicking on the
text box with the mouse?
Can the cursor be placed in read-only fields by clicking in the field
with the mouse?
Is the cursor positioned in the first input field or control when the
screen is opened?
Is there a default button specified on the screen?
Does the default button work correctly?
When an error message occurs does the focus return to the field in
error when the user cancels it?
When the user Alt+Tab's to another application does this have any
impact on the screen upon return to the application?
Do all the fields edit boxes indicate the number of characters they
will hold by there length? e.g. a 30 character field should be a lot
longer
Data Integrity Conditions:
Is the data saved when the window is closed by double clicking on the
close box?
Check the maximum field lengths to ensure that there are no truncated
characters?
Where the database requires a value (other than null) then this
should be defaulted into fields. The user must either enter an
alternative valid value or leave the default value intact.
Check maximum and minimum field values for numeric fields?
If numeric fields accept negative values can these be stored
correctly on the database and does it make sense for the field to
accept negative numbers?
If a set of radio buttons represents a fixed set of values such as A,
B and C then what happens if a blank value is retrieved from the
database? (In some situations rows can be created on the database by
other functions, which are not screen based, and thus the required
initial values can be incorrect.)
If a particular set of data is saved to the database check that each
value gets saved fully to the database. (i.e.) Beware of truncation
(of strings) and rounding of numeric values.
Modes (Editable Read-only) Conditions:
Are the screen and field colors adjusted correctly for read-only
mode?
Should a read-only mode be provided for this screen?
Are all fields and controls disabled in read-only mode?
Can the screen be accessed from the previous screen/menu/toolbar in
read-only mode?
Can all screens available from this screen be accessed in read-only
mode?
Check that no validation is performed in read-only mode.
General Conditions:
Assure the existence of the "Help" menu.
Assure that the proper commands and options are in each menu.
Assure that all buttons on all tool bars have a corresponding key
commands.
Assure that each menu command has an alternative (hot-key) key
sequence, which will invoke it where appropriate.

list can be accessed via appropriate key / hot key combinations.

Assure that the Cancel button operates, as a Close button when
changes have been made that cannot be undone.

window, or in a particular dialog box, are present. – (i.e) make sure

assures that it is grayed out when it should not be used.
Assure that OK and Cancel buttons are grouped separately from other
command buttons.

Assure that all field labels/names are not technical labels, but

combination.
Assure that command buttons in the same window/dialog box do not have

Assure that focus is set to an object/button, which makes sense

Assure that all option buttons (and radio buttons) names are not
abbreviations.
Assure that option button names are not technical labels, but rather

Ctrl + F6 opens next tab within tabbed window

Tabbing will open next tab within tabbed window if on last field of

Banner style & size & display exact same as existing windows
If 8 or less options in a list box, display all options on open of
list box - should be no need to scroll
Errors on continue will cause user to be returned to the tab and the
focus should be on the field causing the error. (i.e the tab is
opened, highlighting the field with the error on it)
Pressing continue while on the first tab of a tabbed window (assuming
all fields filled correctly) will not open all the tabs.
On open of tab focus will be on first editable field

Alt+F4 will close the tabbed window and return you to main screen or
previous screen (as appropriate), generating "changes will be lost"
message if necessary.

Ensure all fields are disabled in read-only mode
