Behavior Driven Development is one of the most commonly misunderstood techniques in DevOps, but it is also one of the key enablers of both an Agile culture and true continuous deployment. This talk will attempt to fill in the missing pieces on exactly what BDD is and how your teams can use it to increase communication, drive quality, and reduce waste. We will also connect the dots on why you need a test-first strategy to enable trunk-based development, continuous integration, and continuous deployment. If your business still struggles with monthly or quarterly big-batch releases, this talk will show you what your teams must do to evolve to the next stage of continuous delivery.
How to bootstrap an SRE team into your company. How to hire them, what to have them work on and how to interact with them as a team. Finally some thought on general practices to consider before your SREs arrive. There are also kitten pictures.
A high level introduction to DevOps. Explains what it is, how popular DevOps has become, why DevOps is popular, how DevOps differs from traditional approaches and some next steps to implementation.
DevOps is an increasingly useful tool for achieving business objectives, enabling your teams to work together to improve the efficiency and quality of software delivery. However, despite its growing popularity, there is still a lack of clarity over what DevOps actually means, how organizations should do it and what's the best way to get started.
DevOps 101 takes a brief look at the history of DevOps, why it started, what problems it is intended to solve and how you can start implementing it.
The slides were delivered by James Betteley, Head of Education at the DevOpsGuys in a one-hour webinar. The full recording is available here - https://youtu.be/4gC3WpbetKs?t=2s
James has spent the last few years neck-deep in the world of DevOps transformation, helping a wide range of organizations optimize the way they collaborate to deliver better software, faster.

When DevOps talks meet DevOps tactics, companies find that Continuous Integration is the make or break point. And implementing CI is one thing, but sustainable CI takes a little bit more consideration. CI is not all about releases, it is also about knowing more about how your software delivery pipeline works, it's weak points, and how you are doing over time.
Join CloudBees and cPrime as we discuss best practices for facilitating DevOps pipelines with Jenkins Workflow and reveal how the workflow engine of Jenkins CI and “Agilecentric” Devops practices together, support complex control structures, shortens the development cycle, stabilizes environments and reduces defects.

This is a practitioner’s view of testing and testing practices within an iterative development environment. We will explore the challenges of testing within such an environment and ways to better integrate the QA professional into what is inherently a developer-centric methodology. If quality is paramount, then we ought to move testing to the front of the line and test early and often. Automation lies at the heart of agility and we will look at how test automation techniques and test-first design philosophy might be applied at multiple-levels to drive quality.
This presentation includes challenges in testing, levels of testing, best practices and policies, Test Drive Design(TDD),
Behavioral Driven Design (BDD Testing), TDD v/s BDD
Building and Scaling High Performing Technology Organizations by Jez Humble a...Agile India
High performing organizations don't trade off quality, throughput, and reliability: they work to improve all of these and use their software delivery capability to drive organizational performance. In this talk, Jez presents the results from DevOps Research and Assessment's five-year research program, including how continuous delivery and good architecture produce higher software delivery performance, and how to measure culture and its impact on IT and organizational culture. They explain the importance of knowing how (and what) to measure so you focus on what’s important and communicate progress to peers, leaders, and stakeholders. Great outcomes don’t realize themselves, after all, and having the right metrics gives us the data we need to keep getting better at building, delivering, and operating software systems.

The Essentials Of Test Driven Development Rock Interview
Test Driven Development is the fastest method to get software onto the market. Being one of the most used methods in the present business world, here is why the method is essential.
ROLE OF iSAFE/iMobi IN SEAMLESS INTEGRATION OF THE DEVOPS ENVIRONMENTIndium Software
IP-led test automation framework supported by blueprint
for product development in Devops environment can
ensure automation in the true sense.
DevOps is fast becoming adopted as the environment for product
development. It facilitates closer integration of development and operations
teams, reducing the time needed to develop and deploy a product. However,
it is still in its early stages and the teams continue to work in silos due to the
different kinds of tools they need suited to their needs.
An IP-driven testing framework like iSAFE can be the bulwark on which the development, testing and operations teams can integrate more seamlessly,
as it provides one key feature needed when handling such a comprehensive
environment – traceability. The other advantages, of course, are reusability,
automated alerts and shorter testing periods, thus aiding in the quick time-to-market
needs of the organizations.
Tester’s considerations when moving towards successful CI/CDDerk-Jan de Grood
These are the slides of the tutorial I gave at QA&Testing in Bilbao on 17 October 2018
Continuous integration and deployment (CI/CD) empowers organizations to bring their solution in production fast and frequent. This interactive session will share the benefits of this concept and introduce eight conditions that need to be met in order to make CI/CD a success. After this brief introduction, we will make small groups and explore these conditions, exchange experiences and you will get an understanding what needs to be improved in your organization. Talk to your peers and learn where they stand. Of course each of the groups will share their learnings, so we all go home with an understanding of how you can benefit from CI/CD and what needs to be done to make it work.
Finally we will see what test strategy we would advise if our company would decide to move towards CI/CD and this cover we consider much more than just automate our tests…

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

• 8000x faster deployment lead time
• 50% less time spent fixing security defects
• 50% lower change-failure rate
• 21% less time spent on unplanned work and

CONTINUOUS DELIVERY
5. 9
• A development practice where developers
integrate code into a shared repository
frequently, preferably several times a day.
• In Continuous Integration, the team should
realize immediately if there are any issues
with the code that prevent it from being
deployed.
• “Continuous Integration doesn’t get rid
of bugs, but it does make them
dramatically easier to find and remove.”
– Martin Fowler
CONTINUOUS INTEGRATION
6. 10
• Ensures that code is always in a ready-to-
deploy state by automatically deploying it
to production.
• Every committed change is expected to be
deployed immediately.
• Deployed is not the same thing as released.
CONTINUOUS DEPLOYMENT

Most software systems share the following
characteristics:
• They are shipped with many defects
• The cost of changing them increases over time
• These systems will need to be replaced every 3-5
years.

TEST-DRIVEN DEVELOPMENT
Test Passes

A style of programming in which three activities
are tightly interwoven: coding, testing (in the
form of writing unit tests) and design (in the form
of refactoring).

WHAT TDD ENABLES
Photo by Ian Stauffer on Unsplash
16. • TDD can’t fix a bad design.
• SOLID design principles still need to be
followed. TDD does not replace
architecture.
• TDD, by itself, does not guarantee
alignment with acceptance criteria.
• Although if you’re doing it right, it should.
• TDD does not mean “Unit Tests”
• It’s perfectly acceptable to include some
integration testing in your TDD effort.
WHAT TDD DOESN’T DO
Photo by Ian Stauffer on Unsplash
17. 21
• You still need lengthy regression-testing cycles before each
release.
• You have frequent production issues with released code.
• Similar issues happen more than once with the same code base.
It is not enough to fix a bug.
You need to guarantee that bug is fixed
forever.
TDD PROBABLY ISN’T BEING DONE IF…

19. 23
Introduced in 2006 by Dan North and Chris
Matts to fix some problems their clients had
experienced with TDD adoption:
• Not knowing where to start
• Not knowing what to and what not to test
• Not knowing how much to test in one
attempt
• Not knowing what to call their tests
• Not understanding why a test fails
BEHAVIOR-DRIVEN DEVELOPMENT
Photo by Harshal S. Hirve on Unsplash
20. 24
The problem, they decided, was one of
language. So they created a couple of
clarifying rules:
• Test method names should be sentences
that include the word “should”
• They replaced the term “Test” with
“Specification”
• They replaced the term “Test Case” with
“Scenario
• They proposed Given-When-Then to model
appropriate test behavior

THE BDD PROCESS

Behavior-Driven Development rests on two central ideas:
THE CORE OF BDD
Ubiquitous Language so that
everyone in an organization
can focus on the problem
domain
System development driven by
Executable Specifications

25. 29
Either side will lead to improvements in your process,
but to get the full benefit, you need to do both.
THE CORE OF BDD
26. 30
Here is what BDD adds to standard TDD practice:
THE CORE OF BDD
System development driven by
Executable Specifications
• Given-When-Then pattern for
creating tests
• Testing behaviors rather than
implementations
• Test case as a sentence that
involves the word “should”
• Guaranteed alignment to
Acceptance Criteria
27. 31
Here is what BDD adds to requirements specification:
THE CORE OF BDD
Ubiquitous Language so that
everyone in an organization
can focus on the problem
domain
• Feature Mapping: requirements
discovery
• Example Mapping: creating
testable scenarios
• Three Amigos: Involving
everyone (not just developers)
in test creation
• Combining test creation with
requirements specification
28. 32
Manual Testing
Unit tests: Most of your tests
should live at this level.
Service tests: More expensive to
run and write. No need to
duplicate Unit tests.
E2E and UI tests: use sparingly.
Manual testing: final validation,
and when you cannot automate.
THE AGILE TESTING TRIANGLE
29. 33
BDD DRAWBACKS/CHALLENGES
BECAUSENOTHINGISEVEREASY
Requires a high level of collaboration with the business. Leaders cannot task out
this work and expect a status report later – they must participate in the process.
BDD will not work in a silo – you cannot outsource the tests and expect success.
Test quality matters – if your tests are bad, you will not get the benefits
31. 35
In order to achieve Continuous Delivery
and/or Continuous Deployment, your
software must always be in a releasable
state. This requires the following:
• Creating a repeatable, reliable process for
releasing software
• Automate nearly everything
• Keep everything in version control
• If it hurts, do it more often
• Build quality in!

THE DEVOPS SKILL TREE
Think of TDD and BDD like the
Animal Husbandry of DevOps.
It may not seem like much
now, but you’ll need it if you
ever want to explore outer
space.

FEATURE BRANCHING
Always in releasable state
Always Unit Tested
Trunk
Feature A
Your trunk (the “master” in Git) should be always releasable.
Every branch (including your trunk) should have a well-
understood policy associated with it.
A developer will take a branch for each feature under
development. Following TDD, this branch will be covered by
unit tests, which are also checked in with the source code.

Integration is re-tested
every day. Problems are
caught earlier. Batch size
is smaller.
Once you get to this point, you do not need any branching
45. 49
Before we all take a flying leap into the
great unknown of continuous integration,
let’s consider the situations in which
doing this won’t work.
JOURNEY TO CI
Photo by Reid Naaykens on Unsplash
46. 50
This is Bob
His new code
changes how we
accept orders.
HOW TO BREAK AN INTEGRATION
This is Gina
Her code re-
categorizes
products.
When they integrate
their code to trunk
that evening…
47. 51
Bob’s code is using the old product object code, so it breaks.
Gina’s code assumes the old order workflow, so it breaks.
The system is down. Angry emails circulate. Dogs start barking.
HOW TO BREAK AN INTEGRATION
48. 52
In order to be delivering continuous integration, we must, at a
minimum, do the following:
• Hide new functionality until it is finished.
• Allow incremental changes to be merged into trunk, even if it’s
currently in an unusable state.
• Again, this depends on TDD/BDD! The
behavior of your code must be
predictable.
HOW TO BREAK AN INTEGRATION
50. 54
At its simplest, a feature flag wraps new functionality in an if/then
structure in order to control its release.
if ( featureExists(“newOrder”)) {
// use the new order/product logic
} else {
// use the old logic
}
WHAT IS A FEATURE FLAG?
51. 55
Even better would be to create a new implementation, and to use
a factory method to control implementation at run time.
WHAT IS A FEATURE FLAG?
if ( featureExists(“newOrder”)) {
// inject the new implementation
} else {
// inject the old implementation
}
NewClass
OldClass
52. 56
TRUNK-BASED DEVELOPMENT
Trunk
Includes
Features
A and B
Feature A
Feature B
Always in deployable state
Code is checked into
trunk.
! !
Feature is switched on,
which releases it to
users. Release is
separated from
deployment.
Feature flags remove the need for branching.

”Hi! Should we wash our
hands before your
operation? What do you
think?”
BUT OUR MANAGERS WON’T LET US!
By the end of this course, you should
understand why development teams do
not need permission to implement
TDD/BDD.
• Automated test-first practices are not
not optional.
• They are a professional duty of care.
56. 65
Maintenance costs for software are between 40% to 80% of total
cost. Many companies myopically optimize for speed through
development phase but neglect the waste that this creates.
IT WILL SLOW US DOWN!
57. 66
Even though BDD feels like it’s slowing you
down, its overall, long-term effect is to speed
you up.
You literally cannot do Continuous Delivery
without solid automated testing.
According to Accelerate, test automation
predicts better IT performance when:
1. Tests are reliable: the team trusts that when
the tests pass, the software is releasable
2. The tests are created by the team, not by an
outside vendor or a siloed QA organization.
BDD’s IMPACT ON DELIVERY SPEED
58. 67
Again, the benefits of true Continuous Integration
and Continuous Deployment far outweigh short-
term costs.
• 44% more time spent on new features
• 50% higher market cap growth over 3 years
• 8000x faster deployment lead time
• 50% less time spent fixing security defects
• 50% lower change-failure rate
• 21% less time spent on unplanned work and
rework
YOU CAN’T AFFORD NOT TO USE BDD
