Running spock unit tests with Maven
Solution 1
Maven Surefire finds test classes by their name. Either change the class name to ATest
, or reconfigure the name pattern used by Surefire. The POM for the spock-example project demonstrates how to do the latter.
Solution 2
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.
Solution 3
I had the same requirement to add Spock to my existing java web app. I tried Peters but it did not work for me. gmavenplus-plugin somehow (no idea) replaced my guava dependency with a very old google lib and my Spring application broke complaining about a non-existent method.
After literally maybe 2 or 3 dozen attempts, I finally was able to integrate my Spock Unit tests, and Integration tests and more importantly to isolate the compilation of the Spock groovy classes from my existing Java/Junit Spring/Hibernate application.
Of course if I had gradle it would have solved the issue...but this is a legacy project and therefore I had not the choice.
Below are the plugins I added. Please note the Spock unit tests end with Spec. The Spock integration tests end with IT (but most probably should be SpecIT). I put my Spock tests under src/test/groovy.
<plugins>
<plugin>
<groupId>org.codehaus.gmavenplus</groupId>
<artifactId>gmavenplus-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<!-- Without joint compilation - no dependencies between Java and Groovy (inheritance)-->
<goals>
<goal>testCompile</goal>
</goals>
</execution>
</executions>
<configuration>
<sources>
<source>
<directory>${project.basedir}/src/main/java/groovy</directory>
<includes>
<include>**/*.groovy</include>
</includes>
</source>
</sources>
<testSources>
<testSource>
<directory>${project.basedir}/src/test/groovy</directory>
<includes>
<include>**/*.groovy</include>
</includes>
</testSource>
</testSources>
</configuration>
</plugin>
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.18.1</version>
<configuration>
<testSourceDirectory>src/test/groovy</testSourceDirectory>
<testSourceDirectory>src/test/java</testSourceDirectory>
<includes>
<include>**/*Spec.java</include>
<!-- Yes, .java extension -->
<include>**/*Test.java</include>
<!-- Just in case having "normal" JUnit tests -->
</includes>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.20</version>
<configuration>
<useFile>false</useFile>
<includes>
<include>**/*IT.java</include>
</includes>
</configuration>
<executions>
<execution>
<goals>
<goal>integration-test</goal>
<goal>verify</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
And here are my dependencies:
<!--Spock -->
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy</artifactId>
<version>2.4.7</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-core</artifactId>
<version>1.1-groovy-2.4</version>
</dependency>
<dependency>
<groupId>org.spockframework</groupId>
<artifactId>spock-spring</artifactId>
<version>1.1-groovy-2.4</version>
</dependency>
<dependency>
<groupId>org.codehaus.groovy.modules.http-builder</groupId>
<artifactId>http-builder</artifactId>
<version>0.7.1</version>
</dependency>
<!--Spock mocking dependencies -->
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib-nodep</artifactId>
<version>3.2.5</version>
</dependency>
<dependency>
<groupId>org.objenesis</groupId>
<artifactId>objenesis</artifactId>
<version>2.6</version>
</dependency>
And just to let you know, my original POM had absolutely no explicit plugins AT ALL. So I had a very simply POM for my project. So, it should work for you. It is a Java 1.7 project.
...and finally, just to give you some confidence that this is not a rubbish post, I did multiple tests in order to ensure the above worked:
Just build the WAR without the tests and deploy and smoke test it locally
mvn clean install -DskipTests -Dmaven.test.skip=trueDo a test compile and see if the Groovy Unit tests get compiled as well
mvn -X clean test-compileDo a clean install without the Integration test (i made sure it was failing for this test) and see if the Groovy unit tests are run
mvn clean install -DskipITsJust run the integration test
mvn failsafe:integration-test
I would have liked to include screenshots of the above as proof but it would have had to be censored...So, I sincerely hope this helps you, as I was going mental trying to get this working...Maven is a huge subject area. Good luck :=)

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
(ormvn 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.)
