SAFe emphasizes Building Quality In. We will take a deep dive into how this looks from a testing organization’s perspective and what does a SAFe implementation mean for Testing/QA professionals. We will map SAFe’s approach to best practices in the “”Agile Testing”” world. We will look at examples from the real world of how traditional testing organizations shift left and evolve towards continuous testing. Learning Objectives and Key Takeaways: Understand how best practices from the “”Agile Testing”” world map to SAFe’s context Learn ideas and patterns for evolving Testing/QA’s role during a SAFe implementation Understand how Test-Driven looks like and how techniques like Acceptance-Test-Driven-Design/Behavior-Driven Development can empower testers as well as improve the flow on SAFe agile teams. See how SAFe’s principles can be used to guide the evolution towards a lean/agile testing organization

comfortable to
release quarterly and
anxious to release
every two weeks. “ “Now releasing every
two weeks is natural. We
are anxious when we
can’t do it [due to holiday
freeze]”

5. But how does the typical Testing
organization leader feel when
seeing the Continuous Delivery
Pipeline vision?

8. The result - only a limited amount
of feedback is early and effective
• A major amount of issues are
discovered only in the “end game”
• finding defects late increases the
cost to fix them exponentially
• The result – the need to do a long
“end game” to accommodate fixing
them, retesting, and even that
turns out not to be enough in some
cases when the complexity of the
big bang “end game” is
overwhelming.

9. Self-Assess – Continuous Testing Dimension
• Individually assess where you are:
1. Sit – All testing happens towards end of release.
2. Crawl – Some testing happens by Testing team in follow up sprints.
Most still towards end of release.
3. Walk – Majority testing happens inside the Agile teams.
Considerable amount still happens before release.
4. Run – Minimal deployment/release-testing is needed – IP iteration
isn’t heavily used for Testing/Hardening
5. Fly – All testing is run continuously. System is always ready for
deployment/release.

#2 - Apply systems thinking
#3 - Assume variability; preserve options
#4 - Build incrementally with fast, integrated learning cycles
#5 - Base milestones on objective evaluation of working systems
#6 - Visualize and limit WIP, reduce batch sizes, and manage queue lengths
#7 - Apply cadence, synchronize with cross-domain planning
#8 - Unlock the intrinsic motivation of knowledge workers
#9 - Decentralize decision-making

First step forward - Achieve Agile Testing Flow
at the Story AND Feature/Epic/Iteration level
Add Feature/Epic level
testing
1. Add Feature/Iteration level
testing. Avoid the long wait
while minimizing costs
2. left-shift more and more testing through
automation, enabling teams using
environments/tools/knowhow and more.
The 3-level Test Strategy
Pyramid -
Story, Feature/
Iteration, Release
Tools, Simulators and environments
available to developers during
development enabling them to build
the software in consideration of the
real world environment

12. Optimize Testing
Batch Sizes
• For each testing type:
– Create the economic
batch size tradeoff
curve
– Figure out Ideal batch
size without further
investment
– Identify enablers that
would enable shifting
batch size to the left
and improving overall
economics

13. The Test Automation Pyramid
• Most expensive automation to develop, run &
maintain, so minimize!!!
• Move majority of E2E testing coverage to
Service/API layer
• QTP/UFT/Selenium/PerfectoMobile/etc.
UI
• “The Workhorse” of enterprise agile
testing
• Created by testers & developers on
agile teams supported by
frameworks/guidance by
Automation CoE
• soapUI, etc.
Acceptance
(Service/API)
• Leverage Agile Teams
developer testing to
reduce coverage needs
• Ability to automatically
detect (through
coverage tools etc.)
what is covered

14. Self-Assess – Test Automation Pyramid
• Individually assess where you are:
1. Sit – Most regression testing is actually manual. There’s some UI based coverage
but can’t keep up.
2. Crawl – Majority of the regression test suite is based on UI-level automation. It is
hard to maintain, slow-running, and brittle – often fails without reason and
requires lengthy analysis. (Semi-Automated)
3. Walk – Inverted pyramid – Developers are writing unit tests for new code that
reduces some need for other coverage for that code, Some API testing exists, Still a
lot of UI based coverage. Some manual testing is needed beyond the automation
pyramid.
4. Run – Tube – Similar amount of coverage coming from each area. Minimal manual
testing still needed.
5. Fly – Upside pyramid with no manual regression testing required and fully
automatic and reliable continuous testing integrated into continuous integration.

Developer verifies the story passes the
team “ready for story testing” criteria:
• Code is “in the build”
• The acceptance tests for this story
pass in the dev env
• Good code coverage using
automated unit tests
• Sanity test passes
Developer marks story
as dev done, ready for
testing
Development done means the acceptance
tests already pass

Tester pulls story into
testing
• Tester finds significantly fewer defects
• Product Owner is happier with how the
story works & finds fewer surprises.
• Both as a result of deeper alignment
achieved in the specification workshops
with ATDD scenarios.

pull more stories into
coding

24. Self-Assess – Test-First Dimension
• Individually assess where you are:
1. Sit – Test design, execution, and automation happens after software is designed,
when interfaces are stable. Story/Iteration Definition of Done doesn’t include
testing
2. Crawl – Test design and execution is included in definition of Done and executed by
the Agile team – test design for each story happens after the story is build/coded.
3. Walk – Test design happens in parallel to defining/building the story. Feedback
from test design can sometimes influence software functionality/design choices.
4. Run – Test design happens FIRST and is always used as feedback/guidance when
defining the story.
5. Fly – Test design happens FIRST and is used to create mini-stories each focusing on
one small slice/scenario that can then be designed and built and tested very quickly
by the team enabling fast effective flow

28. Self-Assess – Test-First Tooling Dimension
• Individually assess where you are:
1. Sit – relying on record&play techniques and cannot support test-first.
2. Crawl – Developers can automate during/before development using APIs.
3. Walk – Whole team can automate significant amounts of coverage
during/before development using a combination of APIs to the system
under test and an ATDD/BDD tool enabling non-developers to create
scenarios.
4. Run – ATDD/BDD tooling runs all functional testing, is integrated into CI,
and is also used for some of the non-functional tests.
5. Fly – We’re super awesome at this, we do it all the time, we’re not willing
to ever go back!

30. Testers need to provide a different kind of
value within an agile team/organization
• Being Champions of the
Product and the
Customer/User.
• Specializing in
Performance/
Security/Load/etc.
• Shining light on where to
focus quality efforts by
analyzing risk probability
and Impact.

31. • QA - Accountable to Quality:
By Enabling it rather than Owning it
• Focus on elaborating scenarios to help guide the
team as well as advanced and exploratory tests –
especially for the riskier stories
• Automation development and execution – a team
responsibility – Developers typically handle the
majority of the automation development
• ATDD/BDD tools enable QA people to guide the
team and enable automation without being
coders themselves.
Agile Tester as Test/QA expert rather than
automation engineer

33. Self-Assess – The Agile Tester Dimension
• Individually assess where you are:
1. Sit – Testers are in a different organization on different teams.
2. Crawl – Teams get allocated ”half a tester”
3. Walk – Agile Teams include testers that focus on that team and can
really support Test-First efforts.
4. Run – Agile Testers cover the majority of testing work including
some of the more specialized test types
5. Fly – Teams look up to their testers to guide the way towards
quality – test-first isn’t just a process it is the way the teams think
and behave.
