Better Software East 2017 - Software Quality & Testing

Has this happened to you? You try to implement a change in your organization, and it doesn’t get the support you thought it would. And, to make matters worse, you can't figure out why. Or, you have a great idea but can’t get the resources required for successful implementation. Jennifer Bonine shares a toolkit of techniques to help you determine which ideas will—and will not—work within your organization. This toolkit includes five rules for organizational change management, a checklist to help you determine the type of change process needed in your organization, techniques for...

Many teams have a relatively easy time adopting the tactical aspects of agile methodologies. Usually a few classes, some tools introduction, and a bit of practice lead teams toward a fairly efficient and effective agile adoption. However, these teams often get “stuck” and begin to regress or simply start going through the motions—neither maximizing their agile performance nor delivering as much value as they could. Borrowing from his experience and lean software development methods, Bob Galen examines essential patterns—the thinking models of mature agile teams—so you can model...

Agile teams are charged with delivering potentially shippable software at the end of each iteration. In fact, some high-performing agile teams with advanced automation can ship working software every day. They achieve regression confidence with extensive automated test suites and other advanced practices. Rob Sabourin shares automation techniques to improve story and feature testing, exploratory testing, and regression testing. Explore ways to fully integrate testing into agile delivery teams by combining test-driven development (TDD) techniques, precise test and tool selection,...

Microservices—one of the latest software architecture styles—promises to deliver benefits such as fast and easy deployment, ease of testing, fine-grained scalability, architectural modularity, and high overall agility. Unfortunately, these benefits are coupled with a lot of complexity. In this product-agnostic architecture tutorial, Mark Richards provides you with an understanding of the microservices architecture style and what hybrids and alternatives exist. This helps you make the right architecture and design decisions for your organization. Mark discusses the core concepts of the...

Tim Lister, along with five of his partners at the Atlantic Systems Guild, have compiled project patterns from their combined 150 years of consulting, and have described them in their Jolt Award winning book, Adrenalin Junkies and Template Zombies: Understanding Patterns of Project Behavior. We all talk about best practices but only a tiny minority of organizations actually practice them all. Not to worry, think of “best practices” for human health. We know all about them, but very few of us actually practice them all. Maybe if someone did arduously practice all health practices, they...

Avoiding siloed development is a tricky business. It’s so easy for agile teams to fall into the rut in which testers only do traditional testing activities, and programmers strictly do their time-worn coding activities. Rob Sabourin shares a number of examples of how testing skills can be applied to a wide variety of activities in an agile project. Testers are among the most skilled team members in story grooming, elicitation, and exploration. Risk analysis in self-organized agile teams empowers testers to drive design decisions. A tester’s affinity analysis skills help clear the way for...

As more applications are hosted on servers, they produce immense quantities of logging data. Quality engineers should verify that apps are producing log data that is existent, correct, consumable, and complete. Otherwise, apps in production are not easily monitored, have issues that are difficult to detect, and cannot be corrected quickly. Tom Chavez presents the four steps that quality engineers should include in every test plan for apps that produce log output or other machine data. First, test that the data is being created. Second, ensure that the entries are correctly formatted and...

Imagine a world where operational data is continuously flowing from applications and devices at an extremely high rate. Now imagine services intercepting this data and analyzing it real time. Sounds futuristic? It's not—it's here today. Mark Richards describes what streaming architecture is all about—what it is, when to use it, and how to implement it in a microservices ecosystem. Mark describes the overall ecosystem for streaming architecture—including a brief discussion about the differences in Apache Spark, Flink, and Hadoop—and then explains how Apache Kafka works. Using live coding...

Do your developers and testers pair—and do it in the best ways? If you can answer yes, then you are among the fortunate ones who have a trusting environment where people have confidence in their work. Unfortunately, a large number of development shops don’t practice pairing in any form. Pair programing was documented in Kent Beck’s book eXtreme Programming Explained, published in 1999. So why is it that eighteen years later many developers and testers do not practice this simple yet effective programming technique? Linda Cook addresses many reasons that people don’t pair. Drawing on...

“Testers [do|don’t] (help) [prevent|detect] problems.” Throughout his career, Damian Synadinos has encountered many variations of this phrase, which uses just a few small words to express many big ideas. It is important to understand what each word means individually to better understand the ideas they convey collectively. The study of the meaning in words is semantics. Damian begins with a brief and broad overview of semantics and some related ideas, which set the stage for deep analysis of each individual word and its potential meaning. We consider: Testers—What might this word mean in...

Developers are charged with developing software at lightning speed, often using new and unreliable technologies. Rob Sabourin shares a task-oriented method for organizing unit testing to help programmers and other team members get to consistently done working code, testing beyond the code. Rob approaches unit testing from the viewpoint of completing all the technical work required to fulfill a requirement, exercising the entire vertical technology stack and going beyond raw code. Programmers learn when and how unit test design can be implemented blending white box and black box techniques...

Docker seems to be taking the IT world by storm. But why all the excitement about yet another virtual machine technology? Because Docker is much more. Korey Earl says that Docker solves many DevOps challenges including process isolation, build once-deploy anywhere, and automated scaling without the resource overhead that comes with virtual machines. Docker can improve resource utilization, infrastructure agility, and the transition from development to operations, allowing IT organizations to support the business rather than holding it back. Join Korey as he reviews the basics of the Docker...

After predominantly being used in the build/test stage, Docker has matured and is expanding into production deployment. Similarly, microservices are expanding from greenfield web services to use throughout the enterprise as organizations explore ways to decompose their monolithic systems to support faster release cycles. Anders Wallgren says running microservices-based systems in a containerized environment makes a lot of sense—both for build and test, and from a runtime perspective in production. This makes Docker and microservices natural companions, forming the foundation for modern...

The change in mindset necessary to become a servant leader is incredibly hard for a scrum master who comes from a command and control background. As a newly minted Professional Scrum Master (PSM I), Ryan returned to his team excited and ready to get underway with a scrum adoption, but he had not fully grasped the concept of servant leadership. Instead of being a change agent, he was an impediment. Ryan’s cautionary tale is a common one. Attendees will learn about the difficulties of becoming a scrum master, how scrum team members need to embrace the scrum values to promote healthy team...

The idea of transformation can be both exciting and frightening. How do we shake off old ways of thinking? What will emerge when the transformation is complete? How will I know the transformation is finished? These are questions and challenges that many product teams face as they make the transformation to agile.

Kevin Stilwell shares his experience and techniques for shaking off old paradigms and practices to break the organizational “muscle memory” that exists in many companies. What emerges will be a high performing product team—and the reward will be well worth the effort.

Love it or hate it, the Scaled Agile Framework (SAFe) was found to be the most used framework for enterprise-level agility in Version One’s annual survey. That said, many aspects of SAFe—including effective portfolio management—are difficult for organizations to implement.

Laura Burke Olson shares Big Wall Planning, a technique that Ipreo uses to “seed” their release trains with high-priority, high-value, and balanced portfolio-level epics. Big Wall Planning engages all aspects of company leadership in deciding the product roadmaps. This is a huge challenge in organizations that...
