How to add Spock tests to existing Maven build with Java unit tests?

[David Karr]

I've seen some "greenfield" examples of setting up Spock tests in a Maven build, but what if I have an existing Maven build with Java unit tests, and I want to add or experiment with Spock tests, in addition to the Java unit tests?  I know that Surefire needs to be configured to now add "*Spec.java" (apparently not "*Spec.groovy", the logical choice) in addition to the existing "*Test.java".  What plugins and configuration do I need to add, and would I likely have existing plugins that now have to work with both Java and Groovy?

Basically, all you need is a Groovy plugin (to compile your specs) and Groovy/Spock dependencies. The Maven build in https://github.com/spockframework/spock-example has the details (although there are other Groovy plugins for Maven by now).

Cheers,

Peter

I have never tried (with Gradle it works out of the box), but maybe
following sample project would be useful for you:
https://github.com/msakamoto-sf/maven3-junit-spock-testng-mixin
(JUnit, TestNG and Spock)

Btw, there is a comment in pom.xml:
> (mysteriously, ".groovy" dosn't work for Spock's xxxxSpec.groovy, but ".java" work!!)

I am just learning Spock, and I would lovelovelove to use it.  But we need to run tests automatically in Jenkins via Maven on projects that also contain JUnit tests.

In other words we have an existing Eclipse (STS) Java project with JUnit tests, and I want to add Spock tests to it going forward.

Is this the way to do it?

1. Follow instructions at http://mrhaki.blogspot.com/2011/01/spocklight-add-spock-support-to-java.html (updating version numbers).
   
2. Convert Java project to Groovy project.  Can Jenkins run Groovy project JUnit and Spock tests?
   
3. Create new Spock packages.  Or can I put them into folders that already have JUnit tests?
   
4. Write Spock tests.
   

I hope that can work.  I have been reading and experimenting and spinning my wheels a lot.

Hi,

I've done Junit/Spock parallel projects several times. You can find my standard pom at https://github.com/mkutz/demonstration/blob/master/spock-testing/pom.xml.

Running mvn test will execute both, Junit and Spock and Jenkins should be able to find both test result files.

Kind regards
Micha

To put groovy and java code in same folder (what I like) you need something like this:

Now that I have it figured out after much trial and error, making Spock work in an Eclipse Java project is super easy.

1. Start with STS (Eclipse Luna 4.4).

2. Install Groovy/Grails Plugin.

(I unchecked Quicksearch, the two Pivotal Servers, and Spring Dashboard because STS already has them.)

(I unchecked Grails because we don't need it.)

3. Install Spock Plugin (Jspresso).  (This may not be needed.)

4. Modify pom.xml.  I did not make any real changes to your standard pom, Michael Kutz (thank you very much) at https://github.com/mkutz/demonstration/blob/master/spock-testing/pom.xml.  Peter has those wonderful comments in the spock-example pom.xml, thank you, Peter.

5. Download new dependencies:  Select project in Package View and Run > Run As > Maven install.

6. Change Java project to Groovy project (since Groovy knows all about Java):  Select project, right click > Configure > Convert to Groovy Project.

7. Create a Spock test (even alongside a JUnit Java test) and Run > Run As > JUnit test.

Team,.

Does anyone have a sample project that include spring java components with this pom.xml and spock?

Hi.

Just take Spring config from other repositories, for example from here:
http://spock-framework.3207229.n2.nabble.com/Some-tutorials-for-Spock-Spring-Hibernate-Unitils-td7574043.html

Cheers,

Przemek

[Jose Juan Reyes]

What if you publish your code? Maybe I could help you...

[Dmitry Senkovich]

Hi Michael,

I'm working with Maven and Spock, my E2E tests need to be parallized as it run too long. Could please provide configuration that enabled you to run Spock tests concurrently?

Thank you.

Hey Dmitry,

to achieve parallel test execution, you should have a look into the Surefire or Failsafe plugin configuration options for forking and parallel execution.

For Surefire: http://maven.apache.org/surefire/maven-surefire-plugin/examples/fork-options-and-parallel-execution.html

For Failsafe: http://maven.apache.org/surefire/maven-failsafe-plugin/examples/fork-options-and-parallel-execution.html

You'll notice they are pretty much the same.

Kind regards,

Micha

And they should be because Failsafe is almost 100% identical to surefire, AFAIK always based on its sourcecode and always released in the same version, with only a few slight differences.

And here I accidentally deleted the very part of the quote necessary to understand my remark:
