Persistence.xml overridden in Arquillian tests

Question

Arquillian examples mainly show how to construct WarArchive, JavaArchive, etc. I can't find any good example how to override one of jar files which exists in already compile war file.

The reason is that one of the jars contains persistence.xml which I wan't to override to defined for instance hbm2ddl.auto etc.

What is the proper way to do that?

The problem might be that your using ShrinkWrap.createFromZipFile. From my experience with Arquillian it better to create a custom WAR/JAR for each test. The method which creates the deployment usually looks like this:

@Deployment
public static WebArchive createDeployment() {
    //Load dependencies from POM
    final PomEquippedResolveStage pom = Maven
        .resolver()
        .loadPomFromFile("pom.xml");
    final PomEquippedResolveStage dependencies = pom
        .importCompileAndRuntimeDependencies();
    final File[] libs =         
      dependencies.resolve().withTransitivity().asFile();

    return ShrinkWrap
      .create(WebArchive.class,
              "ExampleArchive.war")
      .addPackage(org.example.Example.class.getPackage())
      .addAsLibraries(files)
      .addAsResource("test-persistence.xml",
                    "META-INF/persistence.xml")
      .addAsWebInfResource(EmptyAsset.INSTANCE, "WEB-INF/beans.xml"); 

}

The test-persistence.xml goes into your test resources directory.
