Test Case Name: win-webcontent-jaws

Firefox Web Content on Microsoft Windows: Navigation of Web content using Freedom Scientific JAWS.

Description

This test case describes the approach and methods used to test keyboard navigation and keyboard functions in a web page displayed in the Windows version of Firefox, using the JAWS screen reader. Be sure to follow the test case setup instructions before proceeding with this test case.

The following types of functions will be tested. You can select the provided link for each to go directly to the section.

This test case is based on the IBM Web accessibility checklist, checkpoints 1, 2, 3, 5, 7, 9, and 10.

Scope of test

The goal is to test is to verify that the Firefox Web browser and the JAWS screen reader work together. The focus of this test is Web content that is displayed in the Web browser. This Web page file contains a number of common Web page elements. JAWS should read appropriate information for all elements in this page, as described in this test case.

This test might uncover Firefox bugs or JAWS bugs. Firefox bugs should be reported to the Mozilla.org bug tracking system. JAWS bugs should be reported to Freedom Scientific.

It is impossible include every combination of web page elements here, but the techniques described here can be used when testing other Web pages. This test case does not include applets, plug-ins, or multimedia content. Testers are encouraged to find live Web sites containing those elements, and test them using JAWS also.

Note: The techniques discussed in in this test case are specifically for JAWS and Firefox running on the Microsoft Windows operating system. Learning to use a screen reader such as JAWS takes time and practice. This test case attempts to help a novice use many JAWS features relating to Web page navigation. Read the JAWS Help pages and online manual for more information on how to use JAWS.

Tools required

This test case requires the use of the JAWS screen reader. Information about JAWS can be found on the Freedom Scientific Web site.

Test Case Setup

All of these files must be available for this test case. You may save them all in a file folder on your PC, or, if you have a Web server, they may all be stored in a single directory on the Web server.
  1. win-webcontent-jaws.html (This is the file you are reading right now.)
  2. groovy-longdesc.html
  3. groovyimg.jpg
  4. imgmap2.jpg

Test Case Instructions

  1. Start JAWS.
  2. Open this file with Firefox.
  3. With JAWS running, scroll down through this file within the Firefox browser and follow the instructions written in each section. Do not use the mouse during the execution of this test case.
  4. In the instructions, keystroke sequences are listed in bold type. For example: H means to press the "H" key on the keyboard, or Ctrl+H means to press and hold the Ctrl key, then press and release the H key, then release the Ctrl key.
JAWS Virtual PC Cursor mode

Note about JAWS Virtual PC Cursor Mode:

Because Web pages are essentially "read-only", JAWS uses its Virtual PC Cursor mode when reading Web pages. This mode allows you to navigate the page in a way similar to navigating a word processor document, using the Arrow keys to move forward and backward, up and down.

If you are not familiar with JAWS cursor modes, see the JAWS online documentation for more information.

Tip: You can press Insert+Z to toggle virtual cursor mode on and off. If you have somehow turned virtual cursor mode off, press Insert+Z to turn it back on.

Please note:

JAWS Configuration Manager HTML Options

Note about JAWS Configuration Manager HTML options:

JAWS provides a number of options that govern how much or how little information JAWS will speak in certain situations. To view the HTML options in the Configuration Manager:

These are the options to be used when running this test case. All of these options are default settings, so you should not need to set them manually. Even so, you should verify that these options are set before running this test.

Note: You can select additional verbosity options to increase the amount of information spoken by JAWS, if you wish.

  2. Verify that the table headers are announced as you change rows or columns.
  3. Verify that the table summary is announced when the table is encountered by JAWS.
Table 1: Simple table using column and row headers

In this table, each cell in the first row is a column header, and the first cell of each row is a row header. The table uses the "scope=" attribute to instruct the screen reader that the row and column headers are available. The table summary attribute is as follows: "This table contains 3 columns, first a country name, then the name of the capital city, then the name of the largest city."

Capital city and Largest city of select countries
Country Capital Largest City

End of Additional JAWS feature test section.

Testing Firefox Caret Browsing mode

Firefox provides a feature called Caret Browsing, where a user can navigate a Web page in a way similar to navigating a document in a word processor. Visually, you see an insertion caret (cursor) on the page, and you can use the Arrow keys to move up, down, left, and right, one line or character at a time.

Note: Caret Browsing mode is not really needed when using a screen reader such as JAWS, since the screen reader provides similar functions. However, because a user can potentially enter caret browsing mode even when a screen reader is in use, some testing of that scenario should be done. Failures in this area will not result in VPAT issues.

Follow these instructions to verify the basic functions of Caret Browsing.
  1. Press F7 to start Caret Browsing mode. Select the "Yes" button in the resulting popup (if it displays) to complete the switch to Caret Browsing mode.
  2. Use JAWS text navigation techniques to read the page while in caret browsing mode. For example:
  3. Verify Links, images, and image maps can be properly navigated with JAWS while in caret browsing mode. For example:
  4. Verify you can run JavaScripts with JAWS running while in caret browsing mode.
  5. Verify HTML Form fields and controls can be properly navigated with JAWS while in caret browsing mode.
  6. Verify HTML Frames can be properly navigated with JAWS while in caret browsing mode.
  7. Verify Tables can be properly navigated with JAWS while in caret browsing mode.
  8. Verify Additional JAWS functions work properly while in caret browsing mode. For example:
