Only load a bean once throughout a test suite

[publi1c_stat1c]

Is this possible? I can provide any source code you want, I just want to know if this is possible.

I run my test suite using ant and junit.

Thanks in advance!

If you use springs test support this is already the case unless you specify it otherwise.

[publi1c_stat1c]

Which is accomplished with the @RunWith(SpringJUnit4ClassRunner.class) annotation correct?

[Marten Deinum]

I suggest a read of the test chapter, it is the SpringJUnit4ClassRunner in conjunction with the @ContextConfiguration annotation. As long as that is the same the configuration is already loaded.

[publi1c_stat1c]

I have read the test chapter.

I have both of those annotations, but on every test that derives from my baseclass, in which i put those annotations, I still see the following output:

Which shows each time that sessionFactory gets created. I want to persist the sessionFactory the first time throughout the whole suite, and never load it more than once. Is this possible?

And I have:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:PersistenceHelper-context.xml"})
public class Foo


And all of the tests I use the sessionFactory extend from this class.

Turns out each junit test was being run in a separate jvm. Problem fixed by the earlier suggestions.

[Marten Deinum]

I was just going to suggest that .
