Surefire Unit Test arguments in Maven 2

5 09 2007

To make the surefire plugin to maven2 operate in a seperate jvm instance, and have different jvm args (eg more memory, or profiler) you can change the way in which the unit tests are launched.


 <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <forkMode>pertest</forkMode>
          <argLine>${maven.test.jvmargs}</argLine>
        </configuration>
      </plugin>
    </plugins>

Then you will need to set ${maven.test.jvmargs} in the properties area to keep maven going.


<properties>
	<deploy.target/>
	<maven.test.jvmargs></maven.test.jvmargs>
</properties>

and finally to run

mvn  -Dtest=SearchSoak -Dmaven.test.jvmargs='-agentlib:yjpagent -Xmx128m' test

Some time the maven.junit.jvmargs parameter might appear in maven 2 as it did in maven 1 ?

Hi Sakai
your blog seems usefull, i need to knw that sis u try adding some directory to classpath through surefire,like in case when during the tests the testcases need to refer to some file other than test resources?

I think you should be able to do a -classpath or something like that, Surefire allows jvm args to be passed through, but I have no idea what it will do to the maven 2 classpath. In general the classpath should be completely defined as maven dependencies. If you need something else, a shell script or bat file makes more sense ?

Hi,
Is it possible to configure maven in such a way that a command like mvn test, runs the same test suite multiple times, each time with a different set of configuration arguments?
