*** What is the best way to test a website?

The internet track at Quality Week this year provided a lot of information.
Would recommend "Notes From the Front Lines:  How to Test Anything and
Everything on a Web Site" by Ted Fuller if you didn't get a chance to attend.
Most software testing practices apply.  Change control, bug tracking, release
management, triage, spec reviews, etc...  Special cases do exist - web testing
tools different (link checkers, code validators, load testing, multi-user,
peak or event driven), unique browsers & configurations, security,
reliability, usability, and performance.

It's important to identify what product is that you're testing.  Then develop
test plan.  Pitfalls to watch out for - don't make assumptions because it's
just a web page, it still adds up to bugs and data loss.  Cost of bad quality
with a web application can be on a much higher scale.  With "normal" software,
the user might call customer support.  Whereas an outage with a web
application can cost thousands of dollars per minute.  It's good to have a
test plan to address this possible financial damage.  The traditional model
doesn't hold in web environment, for example with production drops.  End to
end transaction-based process needs more attention for web-based applications.

If you have a web page where user identity is critical to correct delivery of
content, traverse links inside and outside of site to see if you can find a
place where the users' identity can be lost. Knowing user expectations are key
as is sizing the hardware appropriately.  Usability important, it needs to be
easy to use. Content is important.  Not that much different to test
reliability than conventional software program.

Lots of vendors selling test tools, check out their products to help test your
web application.

*** I have no prior experience in QA/Testing, but I am our only tester.  Where
do I start?

Acquire understanding or knowledge about what you've been given to test.  Make
sure to ask - "What do you want to know?"  In the end you don't want your
customer to be unhappy.  Insist that others in the organization be specific
about what they want out of the role.

Find out how users are going to use the system.

Seek out the customer.  Who is the intended customer?  Where they live, what
is their domain?

Set expectations on what you plan to accomplish since you'll probably have a
one to many relationship with development organization.

Ask what you're doing as the only tester with no experience.

Get a hold of some of the good available books like Testing in the Real World.
Determine worst possible situation and exercise that.

*** How do I pass an ISO9000 audit?

Document process thoroughly and accurately.  Individuals will come in to test
how you're doing the process.  Educate the people in your organization on what
you've documented so that there's consistency.  There are some negatives to
it; one being it takes a lot of time.  In this particular example, it took two
staff weeks.  It can also inhibit process improvement since once the audit is
approved it can be hard to change.

One panelist suggested that this is the wrong question and gave an example of
a time when a professor gave out the final exam questions at the beginning of
the course.  Many of the students focused on just getting answers to those
questions without attempting to gather any other knowledge throughout the
course.

The ISO9000 audit should be a by-product of what they're really up to.

*** What's the best software inspection method?

Requirements.  If you do something up front it has more impact.  The greatest
contributions are made by getting a bunch of diverse people together and have
them each do the inspection.  Had a lot more value doing this versus having
folks come together in a meeting and building consensus.

Not as necessary to have face-to-face meetings as people thought.  Software
inspections can be quite effective when people are dispersed across the
country.

There are several competing software inspection methods.  Not familiar with
all of them.  Activity of asking people to thing carefully about what they're
looking at.  Ask producers of software to think more carefully about what
they're producing.  Best inspection process is one that's actually done.

Really supports power of inspections.  1/2 of all errors are actually
discovered at the requirement level.  By testing the requirements up front you
can save a lot of time in testing.

Question from audience on the different levels of inspections.  Reviews are
typically with a larger audience, larger project.  The idea is you get several
people together with different points of view.

What matters is not the performance of the view but the preparation of the
reviewers.

Also important is the diversity of the reviewers

The real question is:  What are you actually looking for?

*** Does test automation really work? If not, why not?

Yes

Maybe or sometimes.  A lot of things can be automated, a lot of things
couldn't possibly automated.  The important question is:  "What are you trying
to do?"  If you know that, then you can decide if automation will help you.
This question is vague.

I'm a big proponent of test automation.  Important consideration is expected
life of the test suite versus expected labor.  Test automation can be buggy
and is never as easy to do as you might think.  It may take months and months
of work before it is usable.  Doing tests over and over and over without
automating them is just plain stupid.

Question is:  "What is appropriate to automate?"  Use appropriate technology
for appropriate tests.


Is it true that testers are usually uneasy about whether the testing executed
was enough or not? For this seems like setting an "Exit Criteria" is the way
to go. Let me hear in detail about this "Exit Criteria".

Any good tester should feel uneasy when you are about to ship.  Every time I
have been around ship mode I have been second-guessing, it comes with the
territory.  As far as exit criteria, does a checklist help me to feel better?
No, but all along in the product we should have milestones with certain exit
criteria.  You can know how much testing was done and how many changes were
made.  Important questions can be answered like:  What is the mean time
between failure?  Are we checking the developers?  But at the end game there
is a judgment process that is inevitable.  The triage process is critical.  It
considers cost of delay, risk, cost of change, etc.  If you have Exit
Criteria, make sure you communicate to your test team that you might waive
part of your criteria.

There is very little chance you will have a 100% assurance on anything.  Make
sure that your client understands that there is no such thing as exhaustive
testing.  Agree on the degree of assurance for the different factors.  Do not
take on a task that says there are no bugs in the product.  Make reasonable
requirements, and create a test plan that stands a good chance of meeting
those requirements.

Set Priorities.  User test, and use that as an exit criteria.  This can help
to fill in documentation.  Focus on whether you have met customer needs.

*** Whatever happened to "mutation testing"?

This was an idea developed where you take a set of test cases, and for that
set determine the validity of those cases.  To do this, you'd take the
program, create all these mutants, run the data through the mutants, and see
what percentage of the data ran through and returned something different.  If
> 90%, then the test data was probably pretty good.

There are still folks doing research in this area.  There is a conference
going to be held this year.

People who were behind the technology were making outlandish claims about its
usefulness, which hurt its credibility and satisfaction.

Quality of test data sets (test cases) can be tested.If you want to know about
one thing, look at its dual.

If you want to know what a function is, look at the function inputs and
outputs.

As time has gone on, people have tended to forget about it.  The upcoming
conference may bring it into the forefront.

          Real World Strategies for Improving the Test Process

                             By Marco Dekkers
                          ProductManager Testing
                         KZA kwaliteitszorg B.V.

                         e-mail: mdekkers@kza.nl

Test is no longer consider a four-letter-word in modern software
development organizations (although technically it is). With the increased
interest in structured testing the subject of improving the test-process
has also become a valid point of discussion. To support efforts in this
field several models for test-process improvement have been developed in
recent years. In addition to providing a theoretical reference for
improving the process, these models also strive to inform the user on
practical issues regarding effective ways of implementation.  Examples of
these models include the Test Improvement Model, Test Organization
Maturity, Testability Maturity Model, Test Process Improvement and the
Testing Maturity Model. One thing most of these models have in common is
that they draw a parallel with the SW-Capability Maturity Model (SW-CMM).
An other common factor is that most of them were developed after 1995.
Although organizations can benefit from using of one or more of these
models, there are significant drawbacks when using them. Examples of these
include:

    * Questionnaires used to ascertain the maturity of the test-process
      sometimes contain an excessive number of questions

    * Typically behavior is diagnosed and not the effects of that
      behavior. For instance, problems organizations are faced with are
      not included in the diagnosis

    * Improvement suggestions are generic and have to be tailored to
      specific circumstances. Most models do not offer any assistance
      towards this end

    * Organizational goals are not taken into account in some models

To achieve the benefits of test-process improvement this article offers
some real-world advice on how to plan, execute and evaluate an improvement
program. Models are viewed as tools that can be used to the organization's
benefit, if used with care. Some general advice on the use of models
includes: use the model as a checklist not as a guideline, focus on
organizational problems not on applying the advice contained in models,
focus on measurable goals and not on maturity levels and above all be
critical.

Based on several years of experience in the field of testing and test-
process improvement, KZA has developed a set of best practices.  Together
these lay the foundation for an effective strategy regarding test-process
improvement.

Before the KZA approach is discussed, it is important to establish in
which circumstances test-process improvement is desirable. One relevant
consideration is whether IT and the quality of software play an important
role in the success of the organization. If not, putting effort into
improving the test-process is not likely to be of particular relevance.

Generally speaking IT plays a central role in most modern organizations,
so in most cases the answer to this question will be "yes".  An other
important factor is whether the organization is willing and able to
change. Willingness typically only exists if there is general awareness of
(the impact of) problems resulting from deficiencies in the test-process.
Also goals have to be stated clearly (as will be discussed in the next
paragraph) and the expected benefits have to outweigh the costs.

The starting point is the formulation of goals the organization wishes to
achieve. These should be specific, measurable, acceptable for the parties
involved, realistic and placed within a specific timeframe. The goals for
test-process improvement should be in line with, and contribute towards
reaching, business goals. Next the current state of affairs is assessed
using a short questionnaire. This focuses not only on behavior but also on
the problems the organization is faced with. Interviews are used to
develop a more complete understanding of the situation.  After it has
become clear what the goals are and the current situation has been
assessed, attention is shifted to identifying possible solutions. During
this phase it is of particular importance to involve members of the
organization. A consultant facilitates the process, but lets others
generate as much ideas as possible. Improvement suggestions are then
checked against a set of criteria.

Examples of these criteria include:  actions should contribute towards
reaching the goals, adequate resources can be made available and
management and workers are willing to support the proposed measures.
Improvement suggestions that satisfy the criteria are then discussed with
representatives of the organization. This can lead to valuable adjustments
(improvements) and significantly contributes towards acceptance. The next
phase consists of drawing up an action plan and gaining management
approval. A cost/benefit calculation is necessary to make the business
case for test-process improvement.  After the plan has been approved a
project manager is put in charge of an improvement team, which is made up
of members of the departments involved. A critical success factor is
effective communication with all layers of the organization. Change
management skills and techniques are also of vital importance since
resistance to change is likely to increase during the implementation
phase. Effective communication regarding the goals and activities,
training, support and negotiation are the keys to success. In order to
establish the effectiveness of the process improvement effort results are
evaluated both on a periodic and an event-driven basis. This may lead to
corrective actions.

In closing I would like to give some general advice. In contrast to
widespread notions, testing is not conducted in a vacuum. If possible not
only the test-process, but the entire software development process has to
be improved upon. This will prevent sub-optimization from occurring. Also
be sure to incorporate "quick wins" in your action plan so results are not
only achieved "down the line", but rather can be demonstrated in the short
term. This will improve your chances of not only gaining, but also
maintaining management and workforce support.  Involve as many people as
possible in order to gain the necessary commitments. Be sure the
improvement team does not become a separate entity, separated from the
rest of the organization by a virtual brick wall. Widespread involvement
stimulates awareness, commitment and increases the chances of effective
implementation (in that order).

The approach described here is neither perfect nor revolutionary. It does
however work in the real world. Try it for yourself and let me know what
you think of it.

Currently efforts are under way to describe our approach towards test-
process improvement in more detail. During this process the approach will
be refined and adjusted to incorporate as many best practices and insights
as possible, therefore I'd be grateful to receive your feedback. I am very
interested in finding out what challenges you have been faced with when
trying to improve the test-process and how you have dealt with them.
Hopefully, with your help, we can further develop our approach and share
the results in a future issue of QTN.
