Agile Testing is nonsense, because Agile is Testing
Testing is an attitude which brings us to trust results based
on the fact that we can validate them. Testing is an
approach which allows us to think about how to verify we
did the right thing even before starting. Testing is a
practice which allows us to write effective tests that can be
repeated indeﬁnitely while systematically producing
consistent results.

Agile Testing is nonsense, because Agile is Testing
Agile is built around the idea of managing complex projects,
recognizing the importance of emerging results and
verifying in a very disciplined way the assumptions and
hypothesis we make as often and as thoroughly as
possible. This means testing everything we do, every
day … So if you are truly Agile, you are living testing in every
second of your life!

Testing as an Attitude...

attitude: a settled way of
thinking or feeling about
something: he was questioned
on his attitude to South Africa |
being competitive is an
attitude of mind .

Empirical Process Control

Every step performed while

only outcome can be trusted

Iterative and incremental
Stop assuming you already know what the client wants and
discover it while building it together


www.agile42.com |


I need to move from A to B faster than by
walking…


www.agile42.com |


I am not that good at staying in equilibrium,
I need something more stable…


www.agile42.com |


I am stable now, but not fast as I would
like to be, can we go faster?


www.agile42.com |


I figure I am pretty tired in the evening, and
though I like sport, I still need to be faster


www.agile42.com |


What is this?

Inspect the outcome and
learn to validate your
assumptions & hypothesis

trust that their money has been
used wisely...

Testing as an Approach...


www.agile42.com |


approach: a way of dealing with
a situation or problem: we need
a whole new approach to the
job.


www.agile42.com |


Experimenting new things, innovating, requires
dedication and commitment…

We like to learn using short feedback loops

Sometimes we succeed in
validating our hypothesis...

Sometimes we don't...

Why are we
thinking about
what to test and
how to test it
beforehand?

Testing as a Practice...


www.agile42.com |


practice: the actual application
or use of an idea, belief, or
method, as opposed to theories
relating to it: the principles and
practice of teaching | the
recommendations proved too
expensive to put into practice.

Agile Teams normally
work with User
Stories to agree
what needs to be
built and how…

good quicker

- Detail about payment are
visible
- Shipping address is visible
- I can change quantity of

User Stories do have

How do we know if this is working for us?
Necessary Condition (NC), is
what is needed in order to
fulfill the Success Factor

Goal

Represent the Goal
we want to achieve

PSF

NC

Possible Success Factor (PSF)
represent a hypothesis about a
“factor” that would allow to
achieve the Goal


Agile Strategy Map ™
www.agile42.com |


How can we make sure we are not missing
something?
To verify the hypothesis we define what
is needed in order to start a pilot aiming
at verifying the validity of the PSF#1
NC#1.1: we need to list at least 3 projects
per product area
NC#1.1.1: we need to chose projects and
define comparable dimensions such as:
business value, impact, (cost?)
NC#1.2: we need to define a sample
Portfolio funnel, and check that Teams
can deliver with the provided information

NC#1.2

Goal

PSF#1

NC#1.1

NC#1.1.1

PSF#1: we believe that by
consolidating all projects in one
Portfolio, we will be able to make
better business decisions

Ok, it worked… now what’s next?
The Pilot was successful...
The Success Factor,

NC#1.2

becomes Critical (CSF)

NC#1.1

Goal

CSF#1

NC#1.1.1

CSF#1: we have to consolidate
all projects in one Portfolio, so
that will be able to make better
business decisions

1. Testing is an attitude,
because if we embrace the
Agile Manifesto and its
principles, we have to
accelerate learning, and this
requires individual
commitment to validate
assumptions

www.agile42.com |


2. Testing is an approach, it
requires to systematically
initiate everything we do by
understanding the
constraints, the expected
outcomes, and the possible
learnings

www.agile42.com |


3. Testing is a practice,
because once we develop the
attitude and learned the
approach, we will be able to
emerge practices, which will
make us more effective at
learning

www.agile42.com |


4. Everybody makes mistake,
every mistake is an
opportunity to learn, and we
need to be ready to learn and
capitalize on that experience.
If we are not, it will be just a
failure!

www.agile42.com |


5. Testing is a Team
responsibility. Stay away from
boxing responsibilities into
roles… you will hinder selforganization and shared
commitment
