Database Development: The Object-oriented and Test-driven Way

As developers, we've created heuristics that help us build robust systems and employed test-driven development (TDD) to improve code design and counter instability. Yet object-oriented development principles and TDD have failed to gain traction in the database world. That’s because database development involves an additional driving force-the data. Max Guernsey shows how to treat databases as objects with classes of their own-rather than as containers of objects-and how to drive database designs from tests. He illustrates a way to give these database classes the ability to upgrade old data without introducing undue risk. Max also shares how to apply good object-oriented design principles to database classes and how to enforce semantic connections between databases and clients.

Back to the Basics: Principles for Constructing Quality Software

Using an analogy to the building codes followed by architects and contractors in the construction of buildings, Rick Spiewak explores the fundamental principles for developing and delivering high quality, mission-critical systems. Just as buildings are constructed using different materials and techniques, we use a variety of languages, methodologies, and tools to develop software. Although there is no formal "building code" for software, software projects should consider-and judiciously apply-the recognized "best" practices of static analysis, automated unit testing, code re-use, and peer reviews. Rick takes you on a deep dive into each of these techniques where you'll learn about their advantages, disadvantages, costs, challenges, and more.

Cloud-based Testing: Flexible, Scalable, On-demand, and Cheaper

Cloud computing is here to stay-and it is changing the way we test software. Cloud-based testing offers flexible, scalable, and on-demand infrastructure services. And as a bonus, because the cloud offers pay-per-use purchasing options, cloud-based testing usually costs less. Tauhida Parveen describes the concept of cloud-based testing: scope, specific requirements, benefits, and drawbacks. She explains how cloud-based testing brings new capabilities and options for your testing activities-instantly creating and dismantling test environments and miming production environments in early testing. Tauhida discusses how to engineer scalable environments for load, stress, and performance testing. Then, she introduces cloud-based compatibility, cross-browser, and cross-platform testing opportunities you can exploit.

Implementing Agile in an FDA-regulated Environment

While many industries have adopted agile, the medical device industry, which develops products for life-critical applications-where quality and reliability are clearly a top-priority, remains largely stuck under the “waterfall.” Medical device firms must comply with FDA regulations that overwhelmingly suggest a controlled, phase-gated approach to software development. Unfortunately, many companies and development organizations interpret FDA regulations to require a steep waterfall. Many industry long-timers incorrectly see agile as an undisciplined style of software development. Neeraj Mainkar demonstrates how those in regulated industries can overcome these and other hurdles. At Neuronetics, he helped implement key elements of agile while fully complying with FDA regulations.

Agile Development & Better Software West 2012: Agile Testing: Challenges Beyond the Easy Contexts

Don’t let anyone tell you differently: agile testing is hard! First, we have to get over the misconception that you don’t need testers within agile teams. Then, we have to integrate testers with the developers and engender a holistic quality approach. And those are only the challenges when the going is easy! In more difficult contexts, testing in agile environments is-well, even more difficult. Bob Galen explores how to handle testing in difficult contexts-lack of test automation capabilities, agile in highly regulated environments, testing when your team is spread globally and real-time interactions are nearly impossible, and more. He describes contexts and approaches for blending existing, traditional testing techniques with their agile counterparts. With real-world examples, Bob describes how teams have achieved a good working balance between the two-for example, in test planning and quality metrics reporting.

STARWEST 2012 Keynote: State-of-the-Art Cloud Testing: Experiences with Bing Search

The cloud is penetrating every technology organization and almost every software product or service. The cloud affects everything inside development, bringing profound changes to how engineers build, test, release, and maintain software and systems.

STAREAST 2012 Keynote: What Managers Think They Know about Test Automation—But Don’t

Managers play a critical role in the success or failure of test automation. Although most testers and some test managers have a realistic view of what automation can and cannot do, many senior managers have firm ideas about automation that are misguided—or downright wrong.

STAREAST 2012 Keynote: Evaluating Testing: The Qualitative Way

Testers and managers have wrestled with the problem of evaluating software products and testing efforts, often using approaches derived from manufacturing, construction, and physical sciences. These approaches have been partially successful because software products aren't physical products.

Testing in an SOA Environment

Testing Web applications built with service-oriented architecture (SOA) is not the same as testing any other GUI-based application. Testing teams encounter major challenges including errors due to unexpected changes in internal and external services, compliance verification requirements, industry-specific standards, security issues, and more. To address these challenges, teams must adopt new testing methodologies that focus on ensuring the quality of services (QoS) deployed under the SOA development framework. Join Sanjeev Padasalgi as he explains how to plan and deploy a complementary SOA testing framework that addresses compliance, governance, and overall QoS issues. Supporting functional, security, performance, and regression testing, this SOA testing framework addresses Web services testing throughout the development and delivery lifecycle.

Testing and Quality Beyond the Requirements and Code

Many organizations institute testing and quality improvement initiatives focused on testers, developers, and software managers. One stakeholder often ignored in these efforts is the user-your customer. To dramatically improve overall product quality, you must purposefully include the user in your testing efforts. Lanette Creamer illustrates this anecdotally with some important bugs missed, which would not be found even with 100% test and code coverage. Find new ways to collaborate with users and learn how to adopt a customer-based focus on integration and functionality. Explore ideas that will help you consciously “zoom out” to see important gaps in your test coverage. Learn specific techniques to help you and your team find bugs that lurk outside the requirements and beneath the code.
