[I] [improve][test] Add integration tests for the MongoDB source connector [pulsar-connectors]

["david-streamlio (via GitHub)" <gi...@apache.org>]

david-streamlio opened a new issue, #121:
URL: https://github.com/apache/pulsar-connectors/issues/121

   ## Current state
   
   The `mongo` module has integration coverage for the **sink** only: `MongoSinkContainerTest` runs `MongoSink` end-to-end against a real `MongoDBContainer` (Testcontainers, mongo:6.0).
   
   The **source** side has no integration coverage. `MongoSourceTest` is a pure Mockito unit test — it never starts a MongoDB instance, so the change-stream / `MongoSource` read path is exercised only against mocks. (`MongoSourceConfigTest` is config-only.)
   
   ## Proposal
   
   Add a Testcontainers-based integration test for `MongoSource` that:
   
   - starts a real MongoDB container (a replica set, since change streams require one),
   - runs `MongoSource` end-to-end,
   - writes documents to the watched collection and asserts the source emits the corresponding records.
   
   This mirrors the existing `MongoSinkContainerTest` harness on the source side, closing the sink/source coverage asymmetry.
   
   _Part of an integration-test coverage sweep of all connector modules._
