Introducing Spring Framework

Chapter 2 ■ Working with Classes and Dependencies
In this case, it’s the com.apress.isf.java.service.MySearchEngine class and this class will be used by the Spring
Framework to create the instance you need. Next, you defined a “documentType” bean that will create a new instance of
a com.apress.isf.java.model.Type with its values. This will be similar to using the new keyword and the use of setters.
Next, you are going to modify your unit test, and you are going to start using some of the Spring Framework
classes that will start up the container. It will instantiate your classes and it will know about the behavior of your
application. Listing 2-8 shows your unit test class.
Listing 2-8. MyDocumentsTestWithSpring.java
package com.apress.isf.spring.test;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.assertTrue;
import java.util.List;

import com.apress.isf.java.model.Document;
import com.apress.isf.java.model.Type;
import com.apress.isf.java.service.SearchEngine;
public class MyDocumentsWithSpringTest {
private ClassPathXmlApplicationContext context;
private SearchEngine engine;
private Type documentType;
@Before
public void setup(){
context = new ClassPathXmlApplicationContext("META-INF/spring/mydocuments-context.xml");
engine = context.getBean(SearchEngine.class);
documentType = context.getBean(Type.class);
}
@Test
public void testWithSpringFindByType() {
List documents = engine.findByType(documentType);
assertNotNull(documents);
assertTrue(documents.size() == 1);
assertEquals(documentType.getName(),documents.get(0).getType().getName());
assertEquals(documentType.getDesc(),documents.get(0).getType().getDesc());
assertEquals(documentType.getExtension(),documents.get(0).getType().getExtension());
}
