To start, create a {{PersonDaoTest.java}} class in the {{test/dao/**/dao}} directory. This class should extend [BaseDaoTestCase|http://raibledesigns.com/downloads/appfuse/api/org/appfuse/dao/BaseDaoTestCase.java.html], a subclass of JUnit's [TestCase|http://junit.sourceforge.net/javadoc/junit/framework/TestCase.html] which already exists in this package. This parent class is used to load [Spring's|http://www.springframework.org] ApplicationContext (since Spring binds the layers together), and for (optionally) loading a .properties file (ResourceBundle) that has the same name as your {{*Test.class}}. In this example, if you put a {{PersonDaoTest.properties}} file in the same directory as {{PersonDaoTest.java}}, this file's properties will be available via an "rb" variable.

The code you see above is what we need for a basic JUnit test that initializes and destroys our PersonDao. The "ctx" object is a reference to Spring's ApplicationContext, which is initialized in a static block of the [BaseDaoTestCase's|http://raibledesigns.com/downloads/appfuse/api/org/appfuse/dao/BaseDaoTestCase.java.html] class.

The code you see above is what we need for a basic Spring integration test that initializes and destroys our PersonDao. Spring will use autowiring byType to call the ''setPersonDao()'' method and set the "personDao" bean as a dependency of this class.
