Running spock unit tests with Maven

Question

On a previous project I used the Spock testing framework to unit test my Java code. I found this really productive so I am trying to add Spock tests to my current project which uses Maven as its build tool (The previous project used Gradle). While I can get Maven to compile my Spock tests (using groovy-eclipse-compiler), I am unable to get Maven to run the tests.

I've made a simple example to demonstrate my problem with 2 files:

• pom.xml
• src/test/java/ASpec.groovy

Contents of pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">     <modelVersion>4.0.0</modelVersion>     <groupId>my.group</groupId>     <artifactId>my-artifact</artifactId>     <version>0.1-SNAPSHOT</version>      <dependencies>         <dependency>             <groupId>junit</groupId>             <artifactId>junit</artifactId>             <version>4.10</version>         </dependency>             <dependency>             <groupId>org.codehaus.groovy</groupId>             <artifactId>groovy-all</artifactId>             <version>2.0.8</version>             <scope>test</scope>         </dependency>         <dependency>             <groupId>org.spockframework</groupId>             <artifactId>spock-core</artifactId>             <version>0.7-groovy-2.0</version>             <scope>test</scope>         </dependency>     </dependencies>      <build>         <plugins>             <plugin>                 <groupId>org.apache.maven.plugins</groupId>                 <artifactId>maven-compiler-plugin</artifactId>                 <version>3.1</version>                 <configuration>                     <compilerId>groovy-eclipse-compiler</compilerId>                 </configuration>                 <dependencies>                     <dependency>                         <groupId>org.codehaus.groovy</groupId>                         <artifactId>groovy-eclipse-compiler</artifactId>                         <version>2.8.0-01</version>                     </dependency>                     <dependency>                         <groupId>org.codehaus.groovy</groupId>                         <artifactId>groovy-eclipse-batch</artifactId>                         <version>2.1.8-01</version>                     </dependency>                 </dependencies>             </plugin>         </plugins>     </build> </project> 

Contents of ASpec.groovy:

import spock.lang.Specification  class ASpec extends Specification {      def "Test A"(){         // Always fail         expect: false     } }

When I execute mvn clean test (or mvn clean install) I would expect my single unit test to be run and fail. While it is compiled, Maven does not run it. Does any one know how to run a Spock unit test from Maven (or if it is possible?)

(I have not put my test in a package to keep the example simple. Also I have put my groovy code in src/test/java to avoid configuring the example to pick up source files from an additional directory, again to keep the example as simple as possible.)

Answer 1

This answer is purely supplemental to @PeterNiederwieser's answer. In it he mentions that you can configure the name pattern used by Surefire. Here is an example of what worked for me:

<plugin>     <groupId>org.apache.maven.plugins</groupId>     <artifactId>maven-surefire-plugin</artifactId>     <version>2.18</version>     <configuration>         <includes>             <!-- By default only files ending in 'Test' will be included, so also include support for Spock style naming convention -->             <!-- Oddly enough for Groovy files, *Spec.groovy does not work, but *Spec.java does -->             <include>**/*Test.java</include>             <include>**/*Spec.java</include>         </includes>     </configuration> </plugin>

As I mention in the comments, I'm not sure why **/*Spec.groovy didn't work, but I'm happy to be able to use the normal Spock convention here.
