Mocking TransactionManager for testing on Springboot

[Rajith Muditha Attapattu <ra...@gmail.com>]

I'm wondering what's the best way to replace the transaction manager when
running a unit test for a transacted route ?

This is what I did, but can't help think there's a more simple way.
1. I had to specify a TransactionPolicy for my route
2. And then in my test class I used an @TestConfiguration where I created a
mock transaction manager, grabbed a reference to my TransactionPolicy and
used the setTransactionManager to replace with my mock tx manager.

(Without that Camel complains there's more than one Tx managers. Couldn't
figure out a way to replace the existing PlatformTransactionManager bean
which IMO would have been the more straightfoward approach)

My Mock Tx manager is an impl of AbstractPlatformTransactionManager where I
put a log message for begin, commit or rollback.

All though the tests run as expected, I only see the log message for
"being".
I don't see the log message for "commit" for the success case OR "rollback"
for the failure case where an exception is thrown (all though the logs show
that a rollback happened)

I was expecting Camel to call commit or rollback methods of my Mock tx
manager.
