Automated website
accessibility testing can be a very useful process.
It often reveals many issues which would take a human
tester many times longer to uncover. It’s a bit like
using a spell / grammar checker on a long article. But,
just as a human editor is essential in any serious writing,
hands on testing essential in any serious usability
testing effort for the handicapped. Below are the steps
we take beyond automated accessibility tests.
Consultation – Understanding Your Accessibility
Goals What are your reasons for conducting
accessibility testing? What, exactly, do you hope to
achieve? Goals may range from just making sure that
the basics are covered to wanting to win awards for
accessible site design. We help you define your expectations
and turn them into our deliverables.
Planning and Scripting To reach your
goals you need a plan. This includes both high level
planning like which screen readers do you want used,
how many test experts do you want to run the scripts,
and should all pages be tested or just some representative
ones? It also includes specific sets of steps taken
to test conduct tests, known as test scripts.
Recruiting We will test your web presence
with visually impaired specialists who are familiar
with both good and bad web design from their own daily
web use. They are also experts at using screen reader
technologies. If your test plan calls for it we will
also recruit visually impaired target audience testers
– people who represent your potential clients. These
will not be web experts – they will be ordinary web
users.
Conducting the Accessibility and Usability
Tests For most websites, accessibility and
usability testing is conducted over a one to two week
period. However, we never test with multiple testers
concurrently so depending on a client’s needs, the testing
phase can be a bit shorter or significantly longer.
After the data from each tester has been compiled and
they have written their reports, all testers meet to
discuss their findings.
Reporting We provide reporting on
each phase of the project. There is a Goals report which
the client signs off on before moving on to the Planning
phase. The Test Plan and any Scripts are presented for
sign-off prior to actual testing. There can, on client
request, be a Recruiting report. And of course, the
final reports in which we detail the objective results
of testing, the subjective comments of the testers,
and any additional insights from the final meeting.
Both positive and negative issues are reported on. And
there is practical advice on how to improve any negative
issues.
Re-Testing and Reporting Following
any work on the website to resolve accessibility issues
reported on, we can retest the website. This is a recommended
but optional phase and can be a re-running of all previous
tests and scripts or simply a verification test to see
that recommendations were implemented successfully.
Reporting on this phase depends on the scope of testing.

testing for over 10 years.
In 2005 he launched Page Accessibility Labs (PAL) in
order to broaden the world of possibility for handicapped
web users. PAL utilizes the unique skills and experiences
of visually impaired test specialists to ensure complete
test coverage.
PAL specializes in web accessibility and usability
testing.
