How to run junit tests by maven in terminal with JVM arguments

Question

As mentioned in here we can run test methods using,

mvn -Dtest=TestCircle#xyz test

But I need to set some JVM arguments before run the test case. Like I need to use

-Djava.security.manager -Djava.security.policy=mypolicy.policy

How can I tell maven to consider those when running a test case.

Answer 1

Two possible solutions:

First, if your JVM arguments are applicable to all tests, you can add such information as a configuration item for Surefire as follows:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    ...
    <configuration>
        <argLine>-Djava.security.manager -Djava.security.policy=mypolicy.policy</argLine>
    </configuration>
</plugin>

Second, if such JVM arguments are to be applied on a test-by-test basis, they can be specified on the command line as follows:

mvn -Dtest=TestCircle#xyz test -DargLine="-Djava.security.manager -Djava.security.policy=mypolicy.policy"
