I want to know how to integrate comment filed in jira to TestRail,

[Manasingh Suryakanta Pradhan]

I have set up a TestRail free trial integrated with an Atlassian free trial and successfully configured the Jira integration. When you push a defect from TestRail to Jira, it goes through successfully, and any status changes on the Jira ticket are reflected back in TestRail. However, comments added to the Jira ticket are not appearing in TestRail.

Good news: your integration is working as designed. The behavior you're seeing — status changes sync back but comments don't — is a known limitation of TestRail's native Jira integration, not a misconfiguration.

Why comments don't sync back

TestRail's Jira integration uses a polling mechanism that monitors specific fields on linked Jira issues. Per TestRail's official documentation on the Jira integration:

The integration syncs the status and resolution fields from Jira back to TestRail's defect status. It does not sync comments, attachments, or other fields bidirectionally.

The integration was designed for defect status tracking — so you can see whether a pushed defect is Open, In Progress, Resolved, etc. — not for full bidirectional communication.

What does and doesn't sync from Jira → TestRail

Syncs back:

• ✅ Status changes (e.g., Open → In Progress → Done)

• ✅ Resolution field updates

Does not sync back:

• ❌ Comments

• ❌ Attachments

• ❌ Custom field changes

Workarounds

1. Use Jira issue links in TestRail: Each pushed defect in TestRail contains a clickable link to the Jira issue. Team members can click through to read comments directly in Jira.

2. Jira Automation + mapped field (fragile): You could create a Jira Automation rule that copies the latest comment text into a custom text field. If that field is mapped in TestRail's field mapping configuration, it may reflect — but this is not officially supported and can break with formatting.

3. Third-party integration tools: Tools like Exalate or Getint.io offer deeper bidirectional sync between TestRail and Jira, including comments. These are paid solutions but provide the full sync you're looking for.

4. Custom webhook + TestRail API: If you have development resources, you could build a Jira webhook (or Jira Automation "send web request") that fires when a comment is added, then posts it to TestRail via the TestRail API's add_comment endpoint.

Summary

This is a TestRail-side limitation, not an Atlassian/Jira issue. The native integration was scoped to status tracking only. For a feature request to add comment sync, I'd recommend posting on TestRail's community forum or contacting TestRail support directly.

Hope this clarifies things!
