Overview of this book

Gradle is an advanced and modern build automation tool. It inherits the best elements of the past generation of build tools, but it also differs and innovates to bring terseness, elegance, simplicity, and the flexibility to build. Right from installing Gradle and writing your first build file to creating a fully-fledged multi-module project build, this book will guide you through its topics in a step-by-step fashion. You will get your hands dirty with a simple Java project built with Gradle and go on to build web applications that are run with Jetty or Tomcat. We take a unique approach towards explaining the DSL using the Gradle API, which makes the DSL more accessible and intuitive. All in all, this book is a concise guide to help you decipher the Gradle build files, covering the essential topics that are most useful in real-world projects. With every chapter, you will learn a new topic and be able to readily implement your build files.

Testing with TestNG

Working with TestNG is similar to the JUnit integration that we discussed in Chapter 2, Building Java Projects. The very first step is to create the build file with TestNG dependencies and configure the test closure. The following build file adds the TestNG library as the testCompile dependency and in the test closure, we added a testng.xml file to execute the test cases. In this section, we will briefly discuss the use of testng.xml:

apply plugin:'java'

repositories {

dependencies {
  testCompile 'org.testng:testng:6.8.21'

test {
  ignoreFailures = true


However, you can read more about TestNG configuration at

In our example, we have created three test cases named as verifyMapSize, verifyMapNotNull, and addEvenNumbers. These test cases are grouped as Smoke and Integration test cases. If you execute a Gradle test command, all the three...
