Arquillian Persistence Extension was created to help you write tests where persistence layer is involved. Inspired by great framework called Unitils, it brings a bunch of annotations to help you deal with the underlying data storage.
It comes with following features:
-
Wrapping each test in the separated transaction (with commit (default) or rollback at the end).
-
Seeding database using:
-
DBUnit with XML, XLS, YAML and JSON supported as data sets format.
-
Custom SQL scripts.
-
-
Comparing database state at the end of the test using given data sets (with column exclusion).
-
Eviction JPA second level cache between test method invocation, see
@JpaCacheEviction.
-
Glassfish 3.1.2 Embedded
-
JBoss AS 7.0.2 Final (managed)
-
JBoss AS 7.1.1.Final (managed)
-
Wildfly 8.1
-
HSQL
-
MS SQL 2008 Express (with Microsoft JDBC Driver)
-
MySQL 5.5.24
-
PostgreSQL 9.1.4
-
Oracle 11g
-
Derby
Enough talking, let’s see it in action!
@RunWith(Arquillian.class)
public class UserPersistenceTest
{
@Deployment
public static Archive<?> createDeploymentPackage()
{
return ShrinkWrap.create(JavaArchive.class, "test.jar")
.addPackage(UserAccount.class.getPackage())
.addPackages(true, "org.fest") // FEST Assert is not part of Arquillian
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml")
.addAsManifestResource("test-persistence.xml", "persistence.xml");
}
@PersistenceContext
EntityManager em;
@Test
@UsingDataSet("datasets/users.yml")
@ShouldMatchDataSet("datasets/expected-users.yml")
public void should_change_user_password() throws Exception
{
// given
String expectedPassword = "LexLuthor";
UserAccount user = em.find(UserAccount.class, 2L);
// when
user.setPassword("LexLuthor");
em.merge(user);
// then
assertThat(user.getPassword()).isEqualTo(expectedPassword);
}
}There are just two things which are different from the standard
Arquillian test - @UsingDataSet and @ShouldMatchDataSet annotations.
Former seeds the database using file in YAML format, and latter verifies
database state using given file.
This example is taken from integration tests written for this project, so feel free to have a closer look.
But it’s that easy! And there’s more to come!
