Welcome to RBCS, Inc.
Can it really be that 2012
is already half over, and that summer is upon us? It's been a busy year so
far at RBCS, and we're looking forward to the rest of 2012 to be the
This newsletter starts
with some information on our complimentary webinar series. This month
marks our third anniversary of the webinars, and interest continues to
grow. We have our schedule in place for the rest of the year now, and I
think you'll find it interesting.
What will we think of
next? How about a slew of e-books? We have a special section in our
store for e-books now. You'll find many of the expected titles there,
e-book versions of our popular paper books. But you'll also find some
special e-book only versions. These are compact, value-oriented books that
can help you beef up your testing and quality. More information
Back in March, I was in
New Zealand. Why? Well, in addition to being in a beautiful country
with spectacular wine, I was there to attend the ISTQB General Assembly meeting.
While there, I gave an interview on testing in general, and the value of
the ISTQB program specifically. We've got a link to that short interview
Do you have confidence in
the products you are testing? Why? Why not? Can you measure
confidence? Can you communicate about confidence to others? You can
find a quick article on this latest topic in this newsletter.

I've got to say? Don't like it? Want to discuss it? Send an
e-mail to firstname.lastname@example.org, with the keyword "BLOG" in the subject line, and let me know your
thoughts. As time allows, I'll get to these e-mails, and we can discuss
your ideas and mine. Time has been a bit tight lately, but summer might
prove a good time to catch up on the blog. I hope you'll
join me there.

Confidence along the Dimensions of Test Coverage
When I talk to senior project and product stakeholders
outside of test teams, confidence in the system-especially, confidence that it
will have a sufficient level of quality-is one benefit they want from a test
team involved in system and system integration testing. Another key
benefit such stakeholders commonly mention is providing timely, credible
information about quality, including our level of confidence in system quality.
Reporting their level of
confidence in system quality often proves difficult to many testers. Some
testers resort to reporting confidence in terms of their gut feel. Next to
major functional areas, they draw smiley faces and frowny faces on a whiteboard,
and say things like, "I've got a bad feeling about function XYZ." When
management decides to release the product anyway, the hapless testers either
suffer the Curse of Cassandra if function XYZ fails in production, or watch
their credibility evaporate if there are no problems with function XYZ in
If you've been through
those unpleasant experiences a few times, you're probably looking for a better
option. In the next 500 words, you'll find that better option. That
option is using multi-dimensional coverage metrics as a way to establish and
measure confidence. While not every coverage dimension applies to all
systems, you should consider the following:
- Risk coverage: One or more tests (depending on the level of risk) for each
quality risk item identified during quality risk analysis. You can only
have confidence that the residual level of quality risk is acceptable if you
test the risks. The percentage of risks with passing tests measures the residual
level of risk.
- Requirements coverage: One or more tests for each requirements specification
element. You can only have confidence that the system will "conform to
requirements as specified" (to use Crosby's definition of quality) if you test
the requirements. The percentage of requirements with passing tests measures the
extent to which the system conforms.
- Design coverage: One or more tests for each design specification element.
You can only have confidence that the design is effective if you test the
design. The percentage of design elements with passing tests measures design
- Environment coverage: Appropriate environment-sensitive tests run in each
supported environment. You can only have confidence that the system is "fit for
use" (to use Juran's definition of quality) if you test the supported
environments. The percentage of environments with passing tests measures
- Use case, user profile, and/or user story coverage: Proper test cases for
each use case, user profile, and/or user story. Again, you can only have
confidence that the system is "fit for use" if you test the way the user will
use the system. The percentage of use cases, user profiles, and/or user stories
with passing tests measures user readiness.

we had an actual physical storefront and not our virtual store, there would
barely be room to move! We have been adding products every week. Our
two categories that have grown the most since the last newsletter are our
e-books department and our virtual boot camp department.
last week we added two e-books to our E-book category! All of our e-books
are available in Epub or Kindle format.

virtual boot camp lineup is also growing! Boot camps combine a one day
virtual classroom immersion in the Foundation or Advanced syllabus with two

your own organic vegetables isn't just good for you, it's also good for the
environment. Most conventional produce is grown hundreds or even thousands of
miles away and requires significant energy to ship to you. Plus, you avoid
consuming pesticides typically used to grow non-organic produce.
