Gradle Goodness: Specify Spock As Test Framework At Initialization

Since Gradle 2.11 we can specify the test framework to use when we initialise a project with the init task. There is a new option for this task: --test-framework. By default JUnit dependencies are added, but if we specify the value spock the Spock libraries are included in the dependencies section of our build.gradle file.

Let's run the init task to create a Java project with Spock as test framework:

$ gradle init --type java-library --test-framework spock

Let's see the contents of the build.gradle file that is generated:

/*
 * This build file was auto generated by running the Gradle 'init' task
 * by 'mrhaki' at '2/12/16 8:54 AM' with Gradle 2.11
 *
 * This generated file contains a sample Java project to get you started.
 * For more details take a look at the Java Quickstart chapter in the Gradle
 * user guide available at https://docs.gradle.org/2.11/userguide/tutorial_java_projects.html

// Apply the java plugin to add support for Java
apply plugin: 'java'

// Apply the groovy plugin to also add support for Groovy (needed for Spock)
apply plugin: 'groovy'

// In this section you declare where to find the dependencies of your project
repositories {
    // Use 'jcenter' for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
}

// In this section you declare the dependencies for your production and test code
dependencies {
    // The production code uses the SLF4J logging API at compile time
    compile 'org.slf4j:slf4j-api:1.7.14'

    // We use the latest groovy 2.x version for Spock testing
    compile 'org.codehaus.groovy:groovy-all:2.4.5'

    // Use the awesome Spock testing and specification framework even with Java
    testCompile 'org.spockframework:spock-core:1.0-groovy-2.4'
    testCompile 'junit:junit:4.12'
}

Notice in the dependencies section that the Groovy and Spock dependencies are added.
