Setup

Before one can proceed with testing accessibility, one needs to have a basic setup on his/her machine. This section will highlight the different kinds of testing and their relevant test setup.

Enabling Accessibility

To verify the accessible information accessibility needs to be enabled. Accessibility is enabled as follows,

Run “gconftool-2 -s -t boolean /desktop/gnome/interface/accessibility true”

Include 'GNOME_ACCESSIBILITY=1' in the user profile file.

After enabling accessibility, if an application is run from the command prompt, the following messages will be displayed:

Bonobo accessibility support initialized

GTK Accessibility Module initialized

ATK Accessibility Bridge initialized

Currently, accessibility is disabled in GNOME by default.

Simple Testing

A typical GNOME setup would generally suffice in this case. The testing can be manual or automated and doesn't require any specialised tools. Keyboard Navigability and Theme Compliance of an application can be verified in this form of testing.

Keyboard Navigation

Category: Simple Testing

Enable Accessibility: Optional

Test Aim

Mouse usage depends on visual feedback. Keyboard navigation is meant to be an alternative for mouse usage and facilitates visually impaired users. The aim would be to verify that every feature of an application or desktop is usable via keyboard.

Test Setup Notes

Testing can be started after a typical install of the desktop.

Tester Notes

Keep the mouse aside and see if each of the application components can be accessed and activated.
Check if all the actions that can be performed with the mouse can be performed with the keyboard too.
Check if the keyboard bindings are consistent.
For controls having a mnemonic, check if the specific mnemonic gives them focus.
Check if the keyboard shortcuts activate their respective functions. Check if all frequently done actions of the GUI have keyboard shortcuts.
Ensure that using the tab and arrow keys follows a logical tabbing order.
Verify that established conventions are used for keyboard access.

Test Cases: Keyboard Navigation

Theme Compliance

Category: Simple testing.

Enable Accessibility: Optional

Test Aim

In GNOME, all applications should be customisable in terms of colour, font and display layout. GNOME has a special set of themes available for visually impaired which are available through the theme capplet. The test aim here is,

To ensure that the desktop and the applications respect these themes.
A user should be able to override the default settings for an application or the desktop as a whole.

Test Setup Notes

Test can be started after a typical install of the desktop.
Ensure that the accessible themes are available and listed in the Theme Capplet. If it’s not available, then download it from: http://ftp.gnome.org/pub/gnome/sources/gnome-themes/.

Tester Notes

Work with an application across theme, font and size changes and ensure that the themes are respected.
Use the inverse theme and ensure that all information is available. This is equivalent to printing screen shots to a black and white printer and checking for information loss.
Work with all themes and look out for any discrepancies in the user interface of the application when themes are changed.
Check if any information is provided only through colour.
Change the font and check if the settings are maintained.

Test Cases: Theme Compliance

Testing General Principles

Category: Simple testing.

Enable Accessibility: Optional

Test Aim

Mouse interaction: Not everybody can use a mouse with equal dexterity and some users may have difficulty seeing or following the mouse pointer, it is necessary that the mouse interaction guidelines be followed.

Audio: Users who have difficulty hearing, as well as those who work with sound on the computers turned off, will be disadvantaged if the application relies on only sound to convey information.

Test Setup Notes

A typical GNOME release installed on a machine is sufficient. For sound specific testing, a sound card is required on the machine.

Tester Notes

Ensure that all mouse operations can be cancelled through the keyboard and the need for multiple mouse clicks is absent or minimal.
Check if sound is used as the only means of conveying any items of information.

Test Cases: General principles

Testing with Tools

In addition to a typical GNOME setup, one would require to enable accessibility for performing this type of testing. This kind of testing is required to test the accessible information provided by the application to the AT tools. Testing here will exercise the entire accessibility framework. Here the tester/user will be required to install these tools and spend some time getting familiar with them. These tools are:

at-poke
Gnopernicus
GOK

at-poke

Category: Tools Testing

Enable Accessibility: Yes

Test Aim

At development stage, this tool can be used to verify the accessible information provided by an application. The aim here would be to verify the accuracy and completeness of the information provided.

Test Setup Notes

The at-poke sources have to be downloaded from GNOME CVS and built. Alternatively appropriate pre-built binaries can also be used.
A README is also available for the tool at: http://cvs.gnome.org/lxr/source/at-poke/README.
at-poke will require the accessibility components to be installed in addition to the GNOME desktop install.

Tester Notes

Enable accessibility.
Start the application of interest.
Start at-poke. Verify that the application is listed in the at-poke window.
Click on the ‘poke’ button and the application widget hierarchy opens up in a separate window.
Select any widget displayed in the at-poke window. The available accessible information can be checked.
Ensure that appropriate name and descriptions is provided for a widget as per its context.
Check this for all widgets of the application.

Test Cases: at-poke

Gnopernicus

Category: Tools Testing

Enable Accessibility: Yes

Test Aim

The aim here is to test an application’s accessibility via the speech support of Gnopernicus.

Test Setup Notes

Gnopernicus can be used with the following speech synthesisers

Free TTS
Festival
DecTalk
ViaVoice

The install procedure for FreeTTS and Festival have been covered here.

To have Gnopernicus launched by default on login

create directory ~/.gnome2 if it doesn't exist yet
create file ~/.gnome2/session-manual
contents of session-manual file:

[Default]

num_clients=1

0,RestartStyleHint=3

0,Priority=60

0,RestartCommand=gnopernicus

a) Gnopernicus using Free TTS

Requisite non gnome packages- Free TTS
Instructions for installing Free TTS are available here.

b) Gnopernicus using Festival

Requisite non gnome packages- Festival.
Instructions for installing Festival are available here.
The following environment/initialisation variables need to be set. Open the .bash_profile file and add the following lines to it.
export FESTIVAL=1
export LD_LIBRARY_PATH=/gnome2_directory/lib
export GTK_MODULES=libgail:libatk-bridge

Note: Gnopernicus is available in pre-release forms in GNOME CVS. Build and installation instructions are available at http://www.baum.ro/gnopernicus.html#_Toc15444294.

Tester Notes

After the above setup, logout and login into the desktop.
Start Gnopernicus.
Test the various features in sync with an application of choice.
The focus should be to ensure that all critical features of the application are being communicated to the user through voice.

Test Cases: Gnopernicus

GOK

Category: Tools Testing

Enable Accessibility: Yes

Test Aim

An application should be usable via GOK, i.e. keyboard usage should not be needed. The aim here would be to work with an application and the desktop in general via GOK.

Test Setup Notes

GOK testing will need a typical GNOME install setup.

GOK installation instructions can be found at http://www.gok.ca/INSTALL.shtml

Tester Notes

Login into the GNOME desktop
Run GOK.
Start an application.
And try providing input to the application via a pointing device (e.g. mouse) and GOK.
Work using the auto completion and word prediction features of GOK.

Test Cases:GOK

Testing

In the following sections sample instances and detailed testcases are provided for keyboard navigation, theme compliance, general principles, at-poke, gnopericus and GOK.

Test Cases for Keyboard Navigation

Sample Instances

Keynav broken -

In glade application, the widgets from the 'Palette' cannot be selected and placed on say a window with the keyboard.
The individual icons in notification area applet cannot be traversed with the keyboard.

The Test Cases:

Test Case No	Test Case

Font_02	Verify whether objects are labeled with names that make sense when taken out of context.
Font_03	Check if the same label is used more than once in the same window.
Font_04	Check if the labels are positioned consistently. Labels should be immediately below large icons, immediately to the right of small icons and immediately above or to the left of other controls.
Font_05	Ensure that the static labels that identify other controls end in a colon. For e.g., Username: to label a text field into which the user should type their username.
Font_06	Check if labels are used that are spelled differently but sound the same. For e.g. : 'Red' and 'Read'
Font_07	Ensure that static text labels that identify other controls immediately precede those controls in the tab order.

General Principles Test Cases

Sample instance

General principles broken -

In glade, in the 'Project options' dialog, under C options, the labels 'Source File:' and 'Header File:' are repeated.
The popup menu of the individual icons in notification area applet can only be invoked through the mouse.

The Test Cases:

1) Mouse Interaction:

Test Case No	Test Case
Mouse_01	If an application depends on input from mouse button 2 or 3, provide an alternative to do the same operation through keyboard and/or button 1. For e.g. in case of the popup menus that are invoked through mouse button 2, a keyboard alternative is present. Usually all the popup menu functions are available through menu bar so that user can navigate to the menu bar or he can invoke popup menu with Shift+F10 to have the same functionality.
Mouse_02	Check if all mouse operations can be cancelled. Pressing the Esc key should cancel any mouse operation in progress such as dragging and dropping a file in a file manager, or drawing a shape in a drawing program.
Mouse_03	Verify that the application does not warp the mouse pointer, or restrict mouse movement to part of the screen.
Mouse_04	Ensure that the use of chording (pressing multiple buttons simultaneously) is avoided.
Mouse_05	Ensure that for no purpose the use of multiple (triple- or quadruple-) clicking actions is required, unless an accessible alternative method of performing the same action is provided.

2) General Principles:

Test Case No	Test Case
General_01	Verify that all application settings can be restored to their defaults.
General_02	Ensure that after installation, the application can be used without the user having to insert disk or CD at any time. Depending on user's particular disability, they may find it difficult to physically insert or change disks.
General_03	Check if the most frequently used functions are found at the top level of the menu structure. For example in gedit, 'new', 'open', 'close', 'exit' etc should not be deep in the menu structure. It might be difficult for users to remember where to find them and also time consuming to access.
General_04	Ensure that online help and manuals are available.
General_05	Check if confirmation dialogs are available to help prevent users from doing the wrong things like overwriting a file which cannot be easily undone and other mouse actions that could be done by accident.
General_06	Ensure that sound is not used as the only means of conveying any items of information. The user should be given the option to have all audio information provided in a visual way as well
General_07	Check if an option is available to turn off any animation that is used and that the animated information should be available in at least one non-animated format.
