I am using Spock framework for testing (1.0-groovy-2.4 release). Junit offers this option to run a specific test using the command line (with Maven):
mvn -Dtest=TestCircle#mytest test Question: How can I do this with Spock?
This version has a dependency on Junit 4.12, it is stated in Junit documentation that this feature is supported only for Junit 4.x, basically Spock should propose something similar.
After a further investigation, the answer is most probably: No, you can't invoke specific test methods with Spock using that Surefire Plugin feature. Below the reason.
Given the following Spock test case:
import spock.lang.Specification class HelloSpec extends Specification { def hello = new Main(); def sayHello() { given: "A person's name is given as a method parameter." def greeting = hello.sayHello("Petri"); expect: "Should say hello to the person whose name is given as a method parameter" greeting == "Hello Petri"; println "hello from HelloSpec" } } And given the following plugins configuration:
<plugin> <groupId>org.codehaus.gmavenplus</groupId> <artifactId>gmavenplus-plugin</artifactId> <version>1.5</version> <executions> <execution> <goals> <goal>addTestSources</goal> <goal>testCompile</goal> </goals> </execution> </executions> <configuration> <sources> <fileset> <directory>${pom.basedir}/src/test/java</directory> <includes> <include>**/*.groovy</include> </includes> </fileset> </sources> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.18.1</version> <configuration> <includes> <include>**/*Test.java</include> <include>**/*Spec.java</include> </includes> </configuration> </plugin> It runs fine as part of the Maven test phase executing mvn clean test:
------------------------------------------------------- T E S T S ------------------------------------------------------- Running com.sample.HelloSpec hello from HelloSpec Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.314 sec - in com.sample.HelloSpec Even executing mvn clean test -Dtest=HelloSpec you get exactly the same result as above, successfully execution.
So, why we can't run a single method?
If we execute the javap command on the HelloSpec sample test above we get the following output:
Compiled from "HelloSpec.groovy" public class com.sample.HelloSpec extends spock.lang.Specification implements groovy.lang.GroovyObject { public static transient boolean __$stMC; public com.sample.HelloSpec(); public void $spock_feature_0_0(); protected groovy.lang.MetaClass $getStaticMetaClass(); public groovy.lang.MetaClass getMetaClass(); public void setMetaClass(groovy.lang.MetaClass); public java.lang.Object invokeMethod(java.lang.String, java.lang.Object); public java.lang.Object getProperty(java.lang.String); public void setProperty(java.lang.String, java.lang.Object); public java.lang.Object getHello(); public void setHello(java.lang.Object); } So in the generated bytecode there is no sayHello method, because Spock changes methods name in order to allow spaces in them. So the method name you write is never actually the real method name as part of the compiled class.
In this case, the method name is most probably $spock_feature_0_0, not something really friendly.
This is also confirmed in this answer and the comments of Peter Niederwieser, author of Spock actually, so a more than reliable source.
You could try running the following:
mvn clean test -Dtest=HelloSpec#*spock* which should indeed match the real method name, but you would however get an error
This is most likely because with the direct invocation name we are bypassing the glue between JUnit and Spock and as such the execution fails.
I use:
Windows: mvn -Dtest="TestCircle#my test" test *Nix: mvn "-Dtest=TestCircle#my test" test It works perfectly with surefire 2.19.1 and junit 4.8.1. The following is the code example and the execution output:
import spock.lang.Specification class HelloSpec extends Specification { def sayHello() { given: "A person's name is given as a method parameter." def greeting = "Hello Petri"; expect: "Should say hello to the person whose name is given as a method parameter" greeting == "Hello Petri"; println "hello from HelloSpec" } def sayHi() { expect: 1==1 println "sayHi from HelloSpec" } def "say hi to spock" () { expect: true println "say hi to spock from HelloSpec" } } # mvn test "-Dtest=HelloSpec#say hi to spock"
