Test message store copies the message contents to a test message store. We run the quickstarts and verify their results in our internal integration test suite and use TestMessageStore to store the contents so we can verify the results at the end of the action chain.
If you aren't doing a lot of testing, you don't need it, but it's a useful action if you do want to test your .esb archives.
where is that internal integration test suite ??
and how could it help me when i'm doing a test ??
