Get current Spring transaction in JUnit and commit it

问题

is it possible to get current Spring transaction in JUnit?

I want to test JPA in DAO. And DAO do not have transactions. In tests spring create transaction for every method. I want transaction to be commited somewhere in the middle of test. Need it to test DB status. Only solution I found is to create @Rule for every method.

回答1:

You can use TestTransaction in order to manage spring test transactions:

TestTransaction.flagForCommit();
TestTransaction.end();

This will flag the current transaction for commit and end it. After that you can use TestTransaction.start() to start a new transaction.

You can :

• Inject the EntityMananger in your test
• Call flush() after the invocation of your DAO
• Use this EntityManager to test the db

It's always better to keep the default behavior of spring on transaction/rollback in order to minimize side-effects between tests
