Load Testing the MSNBC 2002 Winter Olympics Web Site

When the Canadian pairs figure skating controversy erupted during the 2002 Winter Olympics, TV viewers hit the MSNBC Web site with a fury. But the site was ready and responded without a hitch due to the carefully planned and executed load testing of the voting applications. The MSNBC site received four to five million visitors a day with sudden bursts of traffic due to breaking news. In this session, Suzanne Wagstaff reviews the process she used for planning and preparing to test the MSNBC site, revealing a performance test methodology that works for any scale Web site. Learn about hardware profiling and a process that identifies distributed and on-site risks, including software, hardware, and personnel, to ensure a successful application rollout.

Testers and Testing in the Agile Development

You have heard about agile software development techniques such as eXtreme Programming (XP), Scrum, and Agile Modeling (AM). The industry is buzzing with everything from "this is the greatest thing ever" to "it's just hacking with a fancy new name." Comments like "there is no place for testers because developers and users do the testing now" and "testers play an important role in the agile methods" are both common. Scott Ambler, an early proponent of the agile movement, explains the fundamentals, values, and principles of agile development. He describes a range of agile techniques and explores many myths and misconceptions surrounding agility. Agile software development is real, it works, and it may be an important part of your future in testing. Better testing and improved quality are critical aspects of agile software development, but the roles of traditional testers and QA professionals on agile projects remain unclear.

A Strategic Approach - "Beta the Business"

Beta testing is an industry standard practice to obtain user feedback prior to general availability of software. Have you ever considered that the Beta release can be used to validate the software's value to customers and application users? Extending the Beta concept will result in higher customer satisfaction (and higher revenue for commercial products). Also, you can employ Beta testing to evaluate not only the software product, but the distribution (and sales) process, training, customer support, and usage within your customers' environments. Far beyond just finding defects in the product, you can focus Beta testing on how well the software is meeting your customers' needs. What does that mean to the Development team and the organization as a whole? What are the risks and challenges that we face? What are the rewards?

Open Source Development Tools: Coping with Fear, Uncertainty, and Doubt

Using open source tools in a development and test environment can be a big relief for your budget. However, open source remains a foreign and often frightening concept for many developers and organizations. Today, open source options are available for all types of tools used in the development process. In this session, you will gain a better understanding of the tradeoffs between choosing open source and commercial tools. In addition, you will learn about the wide variety of open source tools available for many operating environments and how to locate the most robust ones. Danny Faught, who has actively evaluated open source tools as they have evolved over the last five years, provides an honest analysis of the benefits and difficulties you may encounter using these tools for development.

Service-Oriented Architecture - Exposed

Service-Oriented Architecture (SOA), incorporating methods for Web services to communicate dynamically, promises to significantly improve organizational operating efficiency, change the way companies conduct business, and even alter the competitive landscape. However, Service-Oriented Architecture is a strategy rather than an objective, and, like any strategy, it is of no value unless it is implemented. With illustrations from companies who today are using SOA to transform their organizations, Sharon Fay shares current practices for exposing Web services and XML to internal development teams, outsourced development, external trading partners, and customers. Learn why reuse is a key method for supporting integration of SOA implementations and how it is being accomplished. Take away a set of metrics that you can use to measure the level of SOA adoption, development productivity gains, and organizational agility.

eXtreme Architecture and Design for Test

eXtreme programming emphasizes test-first coding-you write the tests before writing the implementation code. You can apply the same approach in design when developing a complex system, including an architecture to support testing. To be successful, systems developed with agile methods must support a high level of testability and test automation. For large distributed systems, more sophisticated testing is needed to help determine which components may be contributing to failures. For such complex systems, you should architect the system for testing rather than add testing functionality as an afterthought. Ken Pugh presents a framework that employs polymorphic-style internal and external interface patterns to ease the work of testing and debugging. He also covers adding test-only functionality, test-only outputs, and test-only logging to interfaces.

Go on Offense: Prevent Web Application Security Breaches

You must successfully test your browser-based applications before hackers do the job for you! Whether you have to worry about critical business applications or government compliance issues like HIPPA (Health Insurance Portability and Accountability Act of 1996) or GLBA (Financial Services Modernization Act of 1999), security failures can cost your organization big dollars, unnecessary embarrassment, or both. Hackers have gone beyond simple exploits of open IP ports and standard applications such as Telnet, FTP, and Sendmail, turning their attention to commercial and custom Web applications. To thwart the hackers, test engineers must focus their efforts on common and uncommon security vulnerabilities within the application, including SQL injections, session hijacking, cross-site scripting, and more.

Design Testability and Service Level Measurements into Software

Design and architecture decisions made early in the project have a profound influence on the testability of an application. Although testing is a necessary and integral part of application development, architecture and design considerations rarely include the impacts of development design decisions on testability. In addition, build vs. buy, third party controls, open source vs. proprietary, and other similar questions can affect greatly the ability of an organization to carry out automated functional and performance testing-both positively and negatively. If the software or service is delivered to a separate set of end-users who then need to perform testing activities, the problems compound. Join Jay Weiser to find out about the important design and architecture decisions that will ensure more efficient and effective testability of your applications.

Take Your Iterative Development Practices to the Next Level

Whether you are using the Rational Unified Process (RUP), agile methods, spiral development, or a home grown iterative approach, there are some fundamental practices that can make a big difference. Esther Derby looks at ways to manage schedules and resources, keep progress visible, mitigate risk, and dynamically improve estimates throughout the project. After comparing and contrasting popular iterative process models, Esther offers practical, easy to implement practices to enhance your current process. You will take away some process "gems" that she has collected in her consulting practice, including: use of product backlogs for driving ownership and priorities, burn down charts, ROI measures of requirements, and ways to obtain vital feedback at every iteration.

Testing your Web Site for Privacy, Quality, and Accesibility

Today's business world relies heavily on transactions conducted through the web. Because of this, brand image and how a web site is rendered to customers has become increasingly important. A poorly functioning web site poses significant risk for web-based companies. This presentation discusses the challenges involved when testing to ensure the quality of your company's web site and to ensure that the components of the site function properly. With the ever-increasing web complexity, specific tools and processes are required to manage these challenges.

  • Discover ways to ensure that your web site reflects your privacy policy
  • Learn how to manage your web sites's links to ensure that they remain current and unbroken, and ensure that web content is accessible to users
  • Learn about specific tools and processes to test and manage your web site
