Hi @loustler , I thinked about it again, is it possible to add a UT to cover the newly added logic?

Hi @Hisoka-X

What does a UT means? What a UT stand for?

You mean Unit Test? If it correct, how about a new e2e test case for it?

Sorry. You are right, unit test. But I think add a e2e test case for this small feature is too heavy. We can add some unit test in https://github.com/apache/seatunnel/tree/e31c9c2a9a0804fd24f3ad16ab28fa4fd7ecc2bb/seatunnel-connectors-v2/connector-mongodb/src/test/java/org/apache/seatunnel/connectors/seatunnel/mongodb .
Just like other connectors did. Please refer

You're right. It can be too heavy for this case.

I'll added a unit test for it with another PR
