テスト メソッド トランザクション内でいくつかのデータベース操作を実行したいと考えています。これにはjunit TestRulesを使用したいと思います。ただし、ルールはトランザクションの外部で実行されます。トランザクション内でルールを実行する方法はありますか?
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
"classpath:/META-INF/spring/applicationContext.xml"})
public class ProductServiceTest extends AbstractTransactionalJUnit4SpringContextTests {
public @Rule @Autowired MySimpleSpringRule mySimpleSpringRule;
@Before
public void before() {
logger.debug("before");
}
@After
public void after() {
logger.debug("after");
}
@Test
public void testFindProducts() {
...
と
@Component
public class MySimpleSpringRule implements TestRule {
private class Banaani extends ExternalResource {
@Override
protected void before() throws Throwable {
logger.debug("before");
};
@Override
protected void after() {
logger.debug("after");
};
}
private final Banaani banaani = new Banaani();
@Override
public Statement apply(Statement st, Description desc) {
return banaani.apply(st, desc);
}
結果は
2013-01-18 10:33:24,845 DEBUG [main]: MySimpleSpringRule - before

テスト クラス内の @Before メソッドと @After メソッドはトランザクション内で直接実行されますが、MySimpleSpringRule 内のメソッドはトランザクション外で実行されます。
