Those are my firstimpressions of Meter, a testing tool l've recently fallen in love with -not blindlyWith this book, I share with you my experience with JMeterWhen I was first assigned to use JMeter to perform testing on a particular webapplication I went all out looking for anything on JMeter. Despite plenty of onlinemanuals, article and newsgroup posts printed or e-books were nowhere to be foundSo, when one of the editors of Packtpub approached me with this idea of writinga book on JMeter, I could hear myself saying: Had there been a book on JMeter, Iwould have bought one at any cost. Since no one has written any, why not i writeone? After much contemplation and work, here is the result- what you are readingright nowWhat The book is aboutThis book is about using basic testing tools in JMeter that support software load andregression test automation Meter can be used to test static and dynamic resourcesover a wide range of client/server software(e.g. web applications). For simplicitythis book will focus on a narrowed aspect of Meter while demonstrating practicaltests on both static and dynamic resources of a web application. As this small book isan introductory reference, it is ideally designed to pave the path for the reader to getmore detailed insight on JMeter, and what more it can do beyond this referenceWhat This book coversChapter 1: Automated TestingThe reader who is already automating their tests may want to skip this chapter. Ittakes a quick look at the need to automate testing and whether automation suits allneeds of testing. It provides a quick look at and evaluation of test automation
