Developing Java Applications with Spring and Spring Boot

How to do it...

1. In order to add the Spock tests to our application, we will need to make a few changes to our build.gradle file first. As Spock tests are written in Groovy, the first thing to do is add a groovy plugin to our build.gradle file, as follows:

apply plugin: 'java' 
apply plugin: 'eclipse' 
apply plugin: 'groovy' 
apply plugin: 'spring-boot' 

2. We will also need to add the necessary Spock framework dependencies to the build.gradle dependencies block:

dependencies { 
  ... 
  testCompile('org.spockframework:spock-core:1.1-groovy-2.4-rc-2') 
  testCompile('org.spockframework:spock-spring:1.1-groovy-2.4-rc-2') 
  ... 
} 

3. As the tests will be in Groovy, we will need to create a new source directory for the files. Let's create the src/test/groovy/com/example/bookpub ...
