Next Generation Java Testing or Cisco Wireless LAN Security

Next Generation Java Testing: TestNG and Advanced Concepts

Author: Cedric Beust

Enterprise Java developers must achieve broader, deeper test coverage, going beyond unit testing to implement functional and integration testing with systematic acceptance. Next Generation Java^™ Testing introduces breakthrough Java testing techniques and TestNG, a powerful open source Java testing platform.

Cédric Beust, TestNG's creator, and leading Java developer Hani Suleiman, present powerful, flexible testing patterns that will work with virtually any testing tool, framework, or language. They show how to leverage key Java platform improvements designed to facilitate effective testing, such as dependency injection and mock objects. They also thoroughly introduce TestNG, demonstrating how it overcomes the limitations of older frameworks and enables new techniques, making it far easier to test today's complex software systems.

Pragmatic and results-focused, Next Generation Java^™ Testing will help Java developers build more robust code for today's mission-critical environments.

This book

• Illuminates the tradeoffs associated with testing, so you can make better decisions about what and how to test
• Introduces TestNG, explains its goals and features, and shows how to apply them in real-world environments
• Shows how to integrate TestNG with your existing code, development frameworks, and software libraries
• Demonstrates how to test crucial code features, such as encapsulation, state sharing, scopes, and thread safety
• Shows how to test application elements, including JavaEE APIs, databases, Web pages, and XML files
• Presents advanced techniques:testing partial failures, factories, dependent testing, remote invocation, cluster-based test farms, and more
• Walks through installing and using TestNG plug-ins for Eclipse, and IDEA
• Contains extensive code examples

Whether you use TestNG, JUnit, or another testing framework, the testing design patterns presented in this book will show you how to improve your tests by giving you concrete advice on how to make your code and your design more testable.

Cisco Wireless LAN Security

Author: Krishna Sankar

Expert guidance for securing your 802.11 networks

• Learn best practices for securely managing, operating, and scaling WLANs
• Comprehend the security-related technological underpinnings of WLANs
• Explore new security protocols in 802.11i and WPA and learn how they prevent attacks
• Review centralized deployment models for wired/wireless integration
• Deepen your knowledge of defense by understanding the tools that attackers use to perform reconnaissance and to attack authentication and encryption mechanisms
• Understand how to design secure WLANs to support enterprise applications with the new standards and practices detailed in this book
• Reference the next generation authentication standards and protocols
• Find out about mobility, hotspots, and campus wireless networks
• Grasp Open Authentication, MAC-based authentication, shared key authentication, EAP authentication protocols, WEP, WPA, and 802.11i

Cisco Wireless LAN Security is an in-depth guide to wireless LAN technology and security, introducing the key aspects of 802.11 security by illustrating major wireless LAN (WLAN) standards that can protect the entire network. Because a WLAN is less effective as an isolated piece of the network, this book emphasizes how to effectively integrate WLAN devices into the wired network while maintaining maximum security.

Cisco Wireless LAN Security covers the spectrum of WLAN security, including protocols and specifications, vulnerabilities and threats, and, especially, deployment patterns and design guidelines. With a unique combination of theory and practice, this book addresses fundamentalwireless concepts, such as WEP, and innovations, such as EAP, switching, and management. Each chapter includes detailed illustrations, checklists, design templates, and other resources. You will also find generic wireless deployment patterns based on real-world customer installations and functional examples of architecture, design, and best practices.

Whether you currently design, configure, implement, and maintain WLANs or simply want to explore wireless security issues, Cisco Wireless LAN Security has everything you need to understand how to create a seamlessly secure, impenetrable 802.11 network.

This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
