This document outlines Berk Dülger's professional experience and education. It then discusses DevOps tactical adoption theory, which hypothesizes that each step towards DevOps maturity should provide visible business value to empower continued progression. Continuous testing is discussed as essential to DevOps. Both unit and UI testing are important, but at different stages - unit testing during development and UI testing once functionality is complete. For legacy systems without tests, starting with high-level UI tests provides the most coverage with least effort initially.

vs
Aldous

Brave

1984,
which
is
a
popular
dystopian
novel,
Orwell
feared
what
we
hate
will
ruin
us.
People
are
controlled

feared
what
we

will

11. DevOps
is
not
a
goal,
but
a
process
of
conMnuous
improvement

12. The
idea
here,
it
is
not
required
to
add
the
tools/processes
to
stack
from
sequenBal
beginning
to
end,
but
seeking
benefit.
DevOps
TacMcal

hypothesis
each
step
towards
DevOps
maturity
should
bring
a
visible
business
value
empowering
management
and
team
commitment
for
the
next
step.

13. The
reason
behind
the
theory
is
to
encourage(make
believe)
pracBBoners
to
apply
each
step
one-­‐by-­‐one
and
then
having
the
benefits
in
projects.
Consequently,
each
step
will
be
tested
in
terms
of
uBlity
and
proved
method
validity
for
the
further
steps.

17. A
TacBcal
AdopBon
Example
in
ConMnuous
TesMng

18. UI Testing
(End-to-End
Tests), where you
test the entire system
together to ensure it
does what it is supposed
to do under real life
conditions.
Unit Testing
aims to test small
chunks of your code
in isolation from the
rest of the world.

19. You need both of these in most of projects, but at different
times: unit testing during development (ideally from the very
beginning, TDD!!!), and ui testing later, once you actually
have some complete end-to-end functionality.
If you already have a system running, having no tests,
practically you have legacy code. Start to get the best test
coverage achievable with the least effort first, which means
high level functional(end-to-end) tests.
Adding unit tests is needed too, but it takes much more
effort and starts to pay back later.
