SpringFrameworkのテストでSessionスコープを使うの巻

初歩的なメモ

SpringFrameworkでこう書いて、

	package hoge.hoge.hoge;
	import java.io.Serializable;
	import org.springframework.context.annotation.Scope;
	import org.springframework.stereotype.Component;
	@SuppressWarnings("serial")
	@Component
	@Scope("session")
	public class Hoge implements Serializable {
	private String name;
	public String getName() {
	return name;
	}
	public void setName(String name) {
	this.name = name;
	}
	}

テストこう書いて、

	package hoge.hoge.hoge;
	import static org.junit.Assert.assertEquals;
	import org.junit.Test;
	import org.junit.runner.RunWith;
	import org.springframework.beans.factory.annotation.Autowired;
	import org.springframework.test.context.ContextConfiguration;
	import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
	@RunWith(SpringJUnit4ClassRunner.class)
	@ContextConfiguration({ "file:WebContent/WEB-INF/applicationContext-unittest.xml", "file:WebContent/WEB-INF/web-servlet.xml" })
	public class HogeTest {
	@Autowired
	private Hoge hoge;
	@Test
	public void hogeTest() {
	hoge.setName("hoge");
	assertEquals("hoge", hoge.getName());
	}
	}

実行すると、こうなる

	java.lang.IllegalStateException: No Scope registered for scope 'session'
	at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:322)
	at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:190)
	（略）

ねーぞ、と。
なので、テスト用にSessionスコープをつくってあげます（Requestとか他のスコープも一緒）

	package hoge.hoge.hoge;
	import static org.junit.Assert.assertEquals;
	import org.junit.Before;
	import org.junit.Test;
	import org.junit.runner.RunWith;
	import org.springframework.beans.factory.annotation.Autowired;
	import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
	import org.springframework.beans.factory.config.Scope;
	import org.springframework.context.ApplicationContext;
	import org.springframework.context.support.GenericApplicationContext;
	import org.springframework.context.support.SimpleThreadScope;
	import org.springframework.test.context.ContextConfiguration;
	import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
	@RunWith(SpringJUnit4ClassRunner.class)
	@ContextConfiguration({ "file:WebContent/WEB-INF/applicationContext-unittest.xml", "file:WebContent/WEB-INF/web-servlet.xml" })
	public class HogeTest {
	@Autowired
	private Hoge hoge;
	@Autowired
	private GenericApplicationContext applicationContext;
	@Before
	public void init() {
	ConfigurableListableBeanFactory beanFactory = applicationContext.getBeanFactory();
	Scope sessionScope = new SimpleThreadScope();
	beanFactory.registerScope("session", sessionScope); // ←これ。
	// Scope requestScope = new SimpleThreadScope();
	// beanFactory.registerScope("request", requestScope);
	}
	@Test
	public void hogeTest() {
	hoge.setName("hoge");
	assertEquals("hoge", hoge.getName());
	}
	}

実行


とりあえずとおった。
複数のテストの場合、個別のテストに書くの微妙なのでリスナーを作りましょう。

	package hoge.hoge.hoge;
	import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
	import org.springframework.beans.factory.config.Scope;
	import org.springframework.context.support.GenericApplicationContext;
	import org.springframework.context.support.SimpleThreadScope;
	import org.springframework.test.context.TestContext;
	import org.springframework.test.context.support.AbstractTestExecutionListener;
	public class WebContextTestExecutionListener extends AbstractTestExecutionListener {
	@Override
	public void prepareTestInstance(TestContext testContext) throws Exception {
	GenericApplicationContext context = (GenericApplicationContext)testContext.getApplicationContext();
	ConfigurableListableBeanFactory beanFactory = context.getBeanFactory();
	Scope requestScope = new SimpleThreadScope();
	beanFactory.registerScope("request", requestScope);
	Scope sessionScope = new SimpleThreadScope();
	beanFactory.registerScope("session", sessionScope);
	}
	}

で、ほげテスト君をもとどおりにしてアノテーションでリスナー指定

	package hoge.hoge.hoge;
	import static org.junit.Assert.assertEquals;
	import org.junit.Test;
	import org.junit.runner.RunWith;
	import org.springframework.beans.factory.annotation.Autowired;
	import org.springframework.test.context.ContextConfiguration;
	import org.springframework.test.context.TestExecutionListeners;
	import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
	@RunWith(SpringJUnit4ClassRunner.class)
	@ContextConfiguration({ "file:WebContent/WEB-INF/applicationContext-unittest.xml", "file:WebContent/WEB-INF/web-servlet.xml" })
	@TestExecutionListeners({ WebContextTestExecutionListener.class })
	public class HogeTest {
	@Autowired
	private Hoge hoge;
	@Test
	public void hogeTest() {
	hoge.setName("hoge");
	assertEquals("hoge", hoge.getName());
	}
	}

チクショーDIできてねー(>_<)

	java.lang.NullPointerException
	at hoge.hoge.hoge.HogeTest.hogeTest(HogeTest.java:24)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

どうやらこうらしい。

	package hoge.hoge.hoge;
	import static org.junit.Assert.assertEquals;
	import org.junit.Test;
	import org.junit.runner.RunWith;
	import org.springframework.beans.factory.annotation.Autowired;
	import org.springframework.test.context.ContextConfiguration;

	import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
	import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
	@RunWith(SpringJUnit4ClassRunner.class)
	@ContextConfiguration({ "file:WebContent/WEB-INF/applicationContext-unittest.xml", "file:WebContent/WEB-INF/web-servlet.xml" })
	@TestExecutionListeners({ WebContextTestExecutionListener.class, DependencyInjectionTestExecutionListener.class })
	public class HogeTest {
	@Autowired
	private Hoge hoge;
	@Test
	public void hogeTest() {
	hoge.setName("hoge");
	assertEquals("hoge", hoge.getName());
	}
	}

さいごとのトコちょっと意味不明。
なので、（気が向いたら）つづく。
