Using Personas to Improve Testing Too often testers are thrown into the testing process without direct knowledge of the customers' behaviors and business process. As a tester, you need to think and act like a customer to make sure the software does-in an easy-to-use way-what the customer expects. By defining personas and using them to model the way real customers will use the software, you can have the complete customer view in designing test cases. Get the basics of how to implement customer personas, their limitations, and ways to create tests using them. See examples of good bugs found using personas while learning to write bug reports based on them.
- What you need to know to develop customer personas
- Use customer personas for designing test cases
- The types of bugs found by using personas but missed by other techniques

Managing Agile Test Departments What is the impact of agile methods on test departments and testers? How do you manage testing in an agile test department? Robert Martin, an early adopter and proponent of agile development practices, discusses his experiences and recommendations for how to organize and run an agile test department. He describes the principles, practices, tools, and metrics that are important to successful test management within agile development. Agile methods change the role of test departments from verification to specification. With agile methods, you develop tests before the code, and the tests become the detailed requirements documentation. This paradigm shift has a profound impact on both the test team and the programming team. Learn about the test management problems that often arise in making the transition to agile development and common solutions that address these issues.

Asia as a Test Outsource Center Outsourcing testing software projects to countries in Asia is a trend that is here to stay. You have a growing number of choices for an outsourcing country in Asia-India, China, Taipei, Korea, and others. Although India currently dominates the scene and both Taipei and Korea have historically provided excellent quality, though at a higher cost, China is quickly moving to become the leader with even lower billing rates and a large number of experienced and educated engineers. In this session, Jacob Hsu offers an overview of the Asian outsource scene including the latest trends and data. Take away a checklist of best practices for successfully outsourcing product testing to Asia, including how to manage distributed testing teams, how to overcome language/cultural issues by country, and what types of testing should (and should not) be outsourced offshore.

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?

Getting Started with Test Driven Development Test-driven (or test first) development (TDD) is an excellent method for improving the quality of software applications. It forces the programmer to focus on ensuring that the behavior of the objects at the lowest level of the system is appropriate. It also provides a mechanism to ensure that future source code changes do not break existing behaviors. Using C++ as the example language, Robert Walsh presents an overview of test-driven development, available TDD testing frameworks, and a demonstration of a project started from scratch using TDD. You can apply these concepts to other languages, including Java and Visual Basic. Learn how to overcome the initial hurdles many developers experience when starting out with TDD.
- An introduction to test-driven development using C++ as the example language
- The testing frameworks available for TDD
- Programming tasks that are difficult to implement using TDD

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.

GUI Usability Design and Validation with Paper Prototypes Usability testing of early GUI designs with paper prototypes validates that you are building the right applications for your customers. This low-cost, high-impact practice allows you to rapidly evolve the GUI interface and find many design bugs early in the development process before coding begins. With this process, you can get external customers and internal users actively involved in designing and testing the GUI with tools they can easily manipulate. Based on project experiences at The MathWorks, Inc., you will learn how to move from the paper prototype to a coded GUI and a set of automated tests. In addition, you will learn to develop user documentation while working back and forth between the GUI and the test plan to clarify design choices.
- Involving everyone in GUI design early in the project
- User tasks and scenarios as the basis for GUI validation

Refining Requirements with Test Cases Requirements are supposed to be the basis of most test cases, but can you use test cases to define what the system needs to do--to improve or to actually become the requirements? To some degree, your development process dictates the opportunities you have for test cases to define or refine requirements. However, everyone can benefit from test case writing techniques to identify missing requirements, surface ambiguous statements, and expose implied requirements early in the process. Find out how Tanya Martin-McClellan produces test cases that accurately reflect the requirements, as they are understood at the time, and conducts team reviews to find the gaps and misunderstandings. Although more time is spent writing and rewriting test cases, less time is spent later discussing requirements.
- Find the vaguely defined parts of the requirement definition
- A template of implied requirements you can customize
