Hi @laurynmm and team,

I've implemented the rate limiting fixes for issue #241, and the functionality is working correctly. However, I'm getting a code coverage warning that I'd like your guidance on:

Coverage Warning:

Patch coverage is 6.66667% with 56 lines in your changes missing coverage.

Why this is happening:

The new rate limit monitoring hooks are intentionally wrapped in an environment check:

if (process.env.NODE_ENV !== "test") {
  client.hook.after("request", async (response) => {
    // Rate limit monitoring code
  });
  
  client.hook.error("request", async (error) => {
    // Error handling code
  });
}

This prevents the hooks from interfering with test mocks (which was causing the 4 test failures in claim.js initially). However, since the hooks don't run during npm test, they show as uncovered code.

What I've done:

• The hooks work correctly in production (tested with npm run test:rate-limits)
• All 42 existing tests now pass
• The rate limiting improvements are functional

My question:

What's the preferred approach for this project to handle code that's intentionally excluded from tests?

1. Should I add a separate test file that temporarily sets NODE_ENV=production to test the hooks?
2. Should I add /* istanbul ignore next */ comments to exclude these lines from coverage?
3. Is it acceptable to have this coverage decrease since it's environment-gated production code?
4. Is there a different pattern you'd prefer for adding these monitoring hooks?

I want to make sure I'm following the project's testing standards. Happy to implement whichever approach you recommend!

Thanks for your guidance!

@AdityaSrivastava04 - Have you looked through the contributing guide for how to get help when working on an issue? Glancing at your changes here, you should also review the commit discipline documentation.

Thanks for the guidance! I have reviewed the contribution guide and commit discipline docs.

What I've done so far
Increment the retryCount in the onRatelimit and and onSecondaryRateLimit .Priveously zulipbot would abort after 3 attempts
for primary rate limits ,which caused it to miss webhook events.
Added monitoring hook to log rate limit warnings.

Where I'm stuck
The coverage warning shows 56 uncovered lines because the monitoring hooks are wrapped in
if (process.env.NODE_ENV !== "test")
to prevent interference with test mocks. I understand this causes the coverage decrease, but I'm unsure of the best approach to address this for the PR.

I've cleaned up my commit history as per discipline guidelines.

I don't think that more logging of warnings is something that's going to be particularly useful here, nor was specified in the issue.

Also, this repository doesn't really have an active maintainer, so I'd recommend posting questions and asking for help in our development community. The zulipbot channel is likely a good place to post.

Thanks for the feedback ,

You're right - the additional logging wasn't part of the original issue scope. I've simplified the changes to focus only on what was requested.

I don’t see any evidence that this strategy will address the issue. The “Rate limit exceeded N times” message does not appear in our logs for any N > 1, and neither “aborting” message appears at all.
