= EAR Testing

Example ear-testing can be browsed at https://github.com/apache/tomee/tree/master/examples/ear-testing


The goal of this example is to demonstrate how maven projects might be organized in a more real world style and how testing with OpenEJB can fit into that structure.

This example takes the basic moviefun code we us in many of examples and splits it into two modules:

 - `business-logic`
 - `business-model`

As the names imply, we keep our `@Entity` beans in the `business-model` module and our session beans in the `business-logic` model.  The tests located and run from the business logic module.

=  Project configuration

The parent pom, trimmed to the minimum, looks like so:


[source,xml]

The `business-model/pom.xml` as follows:

And finally, the `business-logic/pom.xml` which is setup to support embedded testing with OpenEJB:

=  TestCode

The test code is the same as always:


[source,java]
----
public class MoviesTest extends TestCase {

    public void test() throws Exception {
        Properties p = new Properties();
        p.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.core.LocalInitialContextFactory");

        p.put("openejb.deployments.classpath.ear", "true");

        p.put("movieDatabase", "new://Resource?type=DataSource");
        p.put("movieDatabase.JdbcDriver", "org.hsqldb.jdbcDriver");
        p.put("movieDatabase.JdbcUrl", "jdbc:hsqldb:mem:moviedb");

        p.put("movieDatabaseUnmanaged", "new://Resource?type=DataSource");
        p.put("movieDatabaseUnmanaged.JdbcDriver", "org.hsqldb.jdbcDriver");
        p.put("movieDatabaseUnmanaged.JdbcUrl", "jdbc:hsqldb:mem:moviedb");
        p.put("movieDatabaseUnmanaged.JtaManaged", "false");

        Context context = new InitialContext(p);

        Movies movies = (Movies) context.lookup("MoviesLocal");

        movies.addMovie(new Movie("Quentin Tarantino", "Reservoir Dogs", 1992));
        movies.addMovie(new Movie("Joel Coen", "Fargo", 1996));
        movies.addMovie(new Movie("Joel Coen", "The Big Lebowski", 1998));

        List<Movie> list = movies.getMovies();
        assertEquals("List.size()", 3, list.size());

        for (Movie movie : list) {
            movies.deleteMovie(movie);
        }

        assertEquals("Movies.getMovies()", 0, movies.getMovies().size());
    }
}
