Want to know the case for Test-Driven Development? Want to know style tips and gotchas for Testing and TDD? Let Alex Chaffee, former Mad Scientist at Pivotal Labs, tell you everything you didn't know you didn't know about testing.
Ever tried doing Test First Test Driven Development? Ever failed? TDD is not easy to get right. Here's some practical advice on doing BDD and TDD correctly. This presentation attempts to explain to you why, what, and how you should test, tell you about the FIRST principles of tests, the connections of unit testing and the SOLID principles, writing testable code, test doubles, the AAA of unit testing, and some practical ideas about structuring tests.
Unit testing has entered the main stream. It is generally considered best practice to have a high level of unit test code coverage, and to ideally write tests before the code, via Test Driven Development.
However, some code is just plain difficult to test. The cost of effort of adding the tests may seem to outweigh the benefits. In this session, we will do a quick review of the benefits of unit tests, but focus on how to test tricky code, such as that static and private methods, and legacy code in general.
Examples are in Java, but the principals are language agnostic.

The Journey to Becoming Cloud Native – A Three Step Path to Modernizing Appli...VMware Tanzu
SpringOne Platform 2016
Speaker: Alois Reitbauer; Chief Technology Strategist, Dynatrace
The cloud has transformed the way we build applications. Early adopters prove that the benefits manifest in delivering value faster to the customer, less operational costs and more productive teams. The interesting question is how to get there, especially if you cannot simply start over and get your current applications benched. Through numerous customer engagements we have learned that there is a pattern followed by companies that do this successfully. This talk show you:
-How to deploy faster without breaking things
-Start decoupling a monolith without breaking your business logic.
-Help developers build application using a new paradigm
-Dynamically scale your applications to save costs
-Manage highly dynamic larger-scale micro services without increasing operational costs
As we will walk through the journey we share learning covering challenges and possible solutions on the organizational, development and operational side. As a company that has gone through this transformation itself while onboarding over 500 new customers we have some interesting stories to share.

The ability to deliver software is no longer a differentiator. In fact, it is a basic requirement for survival. Companies that embrace cloud native patterns of software delivery will survive; companies that don’t - will not.
In this webinar, we will:
- Look at the common patterns that distinguish cloud native companies and the architectures that they employ.
- Discover that an opinionated platform, one that stretches from the infrastructure all the way to the application framework, rather than ad-hoc automation, is an essential component to an enterprise's cloud native journey.
- Show that the combination of Pivotal Cloud Foundry and Spring is the complete cloud native platform.

Pivotal Data Warehouse in the Age of Digital TransformationVMware Tanzu

In the past years of Big Data and digital transformation “euphoria”, Hadoop and Spark received most of the attention as platforms for large-scale data management and analytics. Data warehouses based on relational database technology, for a variety of reasons, came under scrutiny as perhaps no longer needed.
However, if there is anything users have learned recently it’s that the mission of data warehouses is as vital as ever. Cost and operational deficiencies can be overcome with a combination of cloud computing and open source software, and by leveraging the same economics of traditional big data projects - scale-up and scale-out at commodity pricing.
In this webinar, Neil Raden from Hired Brains Research makes the case that an evolved data warehouse implementation continues to play a vital role in the enterprise, providing unique business value that actually aids digital transformation. Attendees will learn:
- How the role of the data warehouse has evolved over time
- Why Hadoop and Spark are not replacements for the data warehouse
- How the data warehouse supports digital transformation initiatives
- Real-life examples of data warehousing in digital transformation scenarios
- Advice and best practices for evolving your own data warehouse practice
Why Domain-Driven Design and Reactive Programming?VMware Tanzu
Enterprise software development is hard.
A poorly designed enterprise software application can result in exorbitant costs and overall project failure. Traditional approaches have had difficulty with promoting good design practices, resulting in applications that don’t meet the needs of the business and are costly and difficult to change. Ultimately, this severely limits the value of these applications.
Domain-Driven Design (DDD) and Reactive Programming are design patterns that address these issues head on. Both approaches address application development complexity by breaking your big problems into smaller problems.
DDD puts the focus on the core business domain ensuring that the highest business value areas are addressed first. DDD operates on the premise that your business needs will change, and your applications need to change accordingly. Working closely together, your business domain experts and technical team can deliver apps that evolve with your business.
Reactive Programming promotes simplicity by focusing on only a few important concepts. It reduces the complexity of building a big application by viewing it as a collection of smaller applications that respond to events. The stream of events that occur as part of your business operations can instantly trigger responses from the application, making Reactive Programming real-time, interactive, and engaging.
In this webinar, we will answer five key questions:
What causes software projects to lack well-designed domains?
What is a good domain model and how does it help with reducing complexity?
What is the Reactive model and how does it help developers solve complex application and integration problems?
How can you use these techniques to reduce time-to-market and improve quality as you build software that is more flexible, more scalable, and more tightly aligned to business goals?
How can in-memory data grids like open source Apache Geode and GemFire (Pivotal’s product based on Apache Geode) fit with these modern concepts?
Are you being asked to put more cloud in your strategy? If you’re like most people, the answer is a definite yes. The word “cloud” can mean so many things, however, that making an actionable strategy is impossible. At Pivotal, we divide cloud into two distinct parts: migrating as many legacy applications into SaaS as possible and focusing on perfecting the software you build in-house that runs your business. Gartner is predicting that by 2020, 75% of applications used to support digital businesses will be built in-house. If you’re one of these companies, you’ll need to quickly evaluate how you develop and run your custom written software.
We believe that soon, every company will either be a software company or losing to a competitor who is. It’s time to focus on the craft of managing the software development life-cycle, and this brief, but dense webinar will help launch your efforts to become a software defined business.
Join us in the last installment in our series: Organization Transformation - to get the full benefit of a cloud native approach, you'll likely need to change how your organization functions and behaves: you'll have to change its culture. When software is thought of more as ongoing products instead of discrete projects, the way the IT department is managed and run changes accordingly. This last part covers the motivations for those changes and outlines how to start transforming everyday management, strategy, staffing, and operations to become a cloud native enterprise.

Pivotal Cloud Foundry: A Technical OverviewVMware Tanzu
"Do your teams release software to production weekly, daily or every hour ? Do you practice software development with tools, process and culture that can respond to the speed of market and customer changes? Agility allows you to experiment with new business models, learn from your mistakes and identify patterns that work. Deliver faster, look for feedback, gain knowledge. In every market, speed wins.
Cloud Native describes the patterns of high performing organizations delivering software faster, consistently and reliably at scale. Continuous delivery, DevOps, and microservices label the why, how and what of the cloud natives, the true digital enterprises."

How to complement TDD with static analysisPVS-Studio
TDD is one of the most popular software development techniques. I like this technology in general, and we employ it to some extent. The main thing is not to run to extremes when using it. One shouldn't fully rely on it alone forgetting other methods of software quality enhancement. In this article, I will show you how the static code analysis methodology can be used by programmers using TDD to additionally secure themselves against errors.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
