   - [ ] Make sure there is a [JIRA issue](https://issues.apache.org/jira/browse/CAMEL) filed for the change (usually before you start working on it).  Trivial changes like typos do not require a JIRA issue.  Your pull request should address just this issue, without pulling in other changes.
   - [ ] Each commit in the pull request should have a meaningful subject line and body.
   - [ ] If you're unsure, you can format the pull request title like `[CAMEL-XXX] Fixes bug in camel-file component`, where you replace `CAMEL-XXX` with the appropriate JIRA issue.
   - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
   - [ ] Run `mvn clean install -Psourcecheck` in your module with source check enabled to make sure basic checks pass and there are no checkstyle violations. A more thorough check will be performed on your pull request automatically.

Review comment:
       I am bit confused here, why do you need to override the endpoint here if the message ordering is enabled? And also it looks the endpoint could be overriden [here](https://github.com/apache/camel/pull/4877/files#diff-fab91f6f43de3fd75a1134f3fe2fda9b52f3d78a45336ab56a758eae05fba1edR129) and hence I don't think this option is needed.

Review comment:
       From what I see the endpoint is used by the  description = "Endpoint to use with local Pub/Sub emulator."
   when running unittests. Also it set's up a NoCredentialsProvider so I guess this is not a 'real' runtime usable property.

Review comment:
       I see. My problem here is that, we will end up with two similar endpoint options which could be a bit confusing to the user. Hence, can we somehow refactor this to only have one endpoint option to be overriden (emulator and API endpoint)? Also, I don't think overriding the endpoint should be only possible when the message ordering is enabled.

Review comment:
       @oscerd Would be good if we could improve this later so that the emulator uses the pubsubEndpoint.
   @omarsmak Agree overriding the endpoint should be possible even without message ordering.

Review comment:
       Okay, then for now we can just enabling the endpoint override without the message ordering. And then later we can do the endpoint refactor (to have only one endpoint option to configure instead of two). Would be great if you can create a JIRA for the proposed improvement.

Review comment:
       You would ideally set the exceptions BEFORE you send or start route, eg
   
   1. set mock expecation
   2. send messages
   3. assert mock
   
   Here you do 2, 1, 3 instead
