Testing from Your Issue Tracker
Use the Certyn browser extension to test, ask questions, and verify fixes directly from Linear, GitHub, Jira, and other tools.
Switching between your issue tracker and your testing tool wastes time and breaks flow. The Certyn browser extension brings AI-powered testing directly into the tools you already use — Linear, GitHub, Jira, Notion, and more.
What It Does
The extension adds a floating chat button to your issue tracker. Click it and you can:
- Ask Certyn — "Is the checkout flow passing?" "What broke since the last deploy?"
- Run tests — Trigger test runs directly from an issue or PR
- Verify fixes — When a bug is marked as fixed, retest it instantly and get results in the same ticket
No tab-switching. No context-switching.
Supported Platforms
The extension works on:
- Linear —
linear.app - GitHub —
github.com - Jira —
atlassian.net - GitLab —
gitlab.com - Notion —
notion.so - Slack —
slack.com - Sentry —
sentry.io - Figma —
figma.com
It automatically detects which platform you're on and adapts accordingly.
Getting Started
- Install the extension from the Chrome Web Store
- Click the extension icon and connect to your Certyn account
- Select your project
- Navigate to your issue tracker — the Certyn button appears
The extension uses the same API key as your dashboard, so there's no separate authentication to manage.
Ask Certyn
The chat interface lets you ask questions about your project's testing status:
"What's the current state of the checkout tests?"
"Which tests failed in the last smoke run?"
"Are there any open critical bugs?"
Certyn answers from live data — test results, execution history, and issue status. It's like having a QA team member always available.
Trigger Tests from Issues
When you're looking at a bug in Linear or GitHub:
"Test the login flow to see if this bug is still happening."
Certyn runs the relevant tests and notifies you when they complete — right in the browser. A notification shows the result with a link to the full session.
Verify Fixes
The most powerful workflow: when a developer fixes a bug, retest it from the ticket.
- Developer pushes a fix
- From the issue in Linear/GitHub/Jira, ask: "Retest this bug"
- Certyn's bug reproducer runs the original reproduction steps
- Results appear as a notification: passed or still failing
- The execution link takes you to full session details with screenshots
No deploy cycles. No manual testing. Just immediate verification.
Tips
- The extension stores your project selection — you don't need to reconfigure each time
- Use keyboard shortcut
Ctrl+Shift+C(Cmd+Shift+Con Mac) to toggle the chat - The chat position (left or right) is configurable in extension settings
- Questions are streamed — you'll see the response building in real-time
- Combine with the GitHub Action for a full workflow: CI gates catch regressions, the extension handles ad-hoc verification
