How to flush data into db inside active spring transaction?

Question

I want to test hibernate session\'s save() method using spring testing framework. @Test method is :

@Test
@Transactional
public void testSave() {
    User ex         


        

Answer 1

Finally I stuck to the following solution:

First, my @Test methods are not running within spring @Transactional support. See this article to know how dangerous it may be. Next, instead of using @Repository beans inside @Test methods I autowire @Service beans which use @Transactional annotation. The miracle is that @Test method like this

@Test
@Transactional(propagation = Propagation.NOT_SUPPORTED)
public void testSave() {
    Answer created = createAnswer();
    Long generatedId = answerService.save(created);
//at this moment answer is already in db
    Answer actual=getAnswerById(generatedId);
... }

puts my Answer object into database (just after answerService.save(created);) and method getAnswerById goes to DB and extracts it to check if save was correct.
To eliminate changes made to database in @Test method I recreate database by JdbcTestUtils.executeSqlScript
