Add persistence.xml from EJB dependency in arquillian test - testing

Question

I have a web maven application that have the database EJB jar as a dependency.
The database EJB is the one which has all the JPA entities and the persistence.xml file, so it's responsible by all database operations.
I just read http://arquillian.org/guides/testing_java_persistence/ and it explains how to test persistence using arquillian.
The tutorial considers that the persistence.xml file is in the webapp path, so it adds META-INF/persistence.xml as a resource.
So I'd like to know, how do I add database's persistence.xml when running the arquillian tests from my webapp? Is that possible?

Answer 1

Maybe the answer comes a little late, but anyhow I hope it's still of value for you:
You have two options, either read the archive from a file (maybe generated my mvn package) or create the archive yourself using ShrinkWrap:
Option (1), called from somewhere annotated with #Deployment:
/** maven did it for us .. we just have to read the file */
private static Archive<?> getArchiveFromFile() {
JavaArchive artifact = ShrinkWrap.create(ZipImporter.class, ARCHIVE_NAME).importFrom(ARCHIVE_FILE)
.as(JavaArchive.class);
return artifact;
}
Option (2), I found it useful to inspect the file from time to time so there's an option to write it to the file system:
/** doing it the hard way ... guess you won't like it as EVERY class plus related stuff needs to be specified */
private static Archive<?> getArchiveManually() {
// creating archive manually
JavaArchive artifact = ShrinkWrap.create(JavaArchive.class, ARCHIVE_NAME)
.addPackage(FooServiceBean.class.getPackage()).addPackage(Foo.class.getPackage())
.addPackage(FooService.class.getPackage()).addAsResource("META-INF/persistence.xml")
.addAsResource("META-INF/beans.xml");
// so we might write it for further inspection
if (WRITE_ARCHIVE) {
artifact.as(ZipExporter.class).exportTo(new File("D:/abc/xyz/tmp/" + ARCHIVE_NAME), true);
}
return artifact;
}
So your answer is included within the second option ;-)
