Introducing Spring Framework

Chapter 2 ■ Working with Classes and Dependencies
As you can see, you just implemented the findByType and you used a private storage method that will retrieve
some documents and their types. Also, you implemented the listAll method that directly uses the storage method.
Note that this is a naïve example to start showing some of the Spring Framework features. Next, you need to test what
you have done. So let’s create a unit test using JUnit (see Listing 2-5).
Listing 2-5. MyDocumentsTest.java
package com.apress.isf.java.test;
import java.util.List;
import org.junit.Test;
import static org.junit.Assert.*;
import com.apress.isf.java.model.Document;
import com.apress.isf.java.model.Type;
import com.apress.isf.java.service.MySearchEngine;
import com.apress.isf.java.service.SearchEngine;
public class MyDocumentsTest {
private SearchEngine engine = new MySearchEngine();
@Test
public void testFindByType() {
Type documentType = new Type();
documentType.setName("WEB");
documentType.setDesc("Web Link");
documentType.setExtension(".url");
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());
}
}
@Test
public void testListAll() {
List documents = engine.listAll();
assertNotNull(documents);
assertTrue(documents.size() == 4);
}
