Overview of this book

The book is based on the author`s experience in leading and transforming large test engagements and architecting solutions for customer testing requirements/bids/problem areas. It targets the testing practitioner population and provides them with a single go-to place to find perspectives, practices, trends, tools, and solutions to test applications as they face the evolving digital world. This book is divided into five parts where each part explores different aspects of testing in the real world. The first module explains the various testing engagement models. You will then learn how to efficiently test code in different life cycles. The book discusses the different aspects of Quality Analysis consideration while testing social media, mobile, analytics, and the Cloud. In the last module, you will learn about futuristic technologies to test software. By the end of the book, you will understand the latest business and IT trends in digital transformation and learn the best practices to adopt for business assurance.

Java performance tuning tools

There are many tools available in the market to analyze and monitor Java applications that help us to find which part of the code should be optimized. Some of them are as follows:

  • NetBeans profiler for analyzing java application
  • JAMon, Java Application Monitor
  • GCViewer, which visualizes verbose garbage collection data generated by Sun and IBM Java Virtual Machines (JVM)
  • HPjmeter , which is specific to Methods/Object
  • HPjtune—JVM

NetBean profiler for analyzing Java applications

The NetBeans profiler is a powerful tool that provides important information about the runtime behavior of an application. The NetBeans profiler helps in tracking the following things:

  • Thread state
  • CPU performance
  • Memory usage
  • Object creation
  • Method creation

Thread state

Threads (Timeline) shows the current and historical thread state, updated as the application runs.

Threads (Details) shows a summary of the thread state information for a single thread.

Refer to the following screenshot:
