Frequently Asked Questions
Everything you need to know about TestScout
TestScout uses advanced JavaScript error detection to automatically capture unhandled errors, promise rejections, and console errors. When an error occurs, it instantly captures a screenshot, console logs, network requests, user actions, and DOM state - all without any manual intervention.
TestScout is currently available for Chrome and Firefox browsers. We're working on support for Edge and Safari. The extension works on all operating systems including Windows, macOS, and Linux.
TestScout is designed to have minimal performance impact. It runs in the background and only activates during error capture. The extension uses efficient buffering and doesn't interfere with your website's normal operation.
Privacy is our top priority. All captured data stays local in your browser - we never collect, store, or transmit any of your debugging data to our servers. You have complete control over what gets captured and exported.
Yes, TestScout is safe for production use. It only captures data when errors occur and includes built-in safeguards to sanitize sensitive information like passwords and form data. You can also configure which domains to monitor.
TestScout allows you to export captured data as JSON files that contain all the debugging context. You can easily share these files with your team members via email, Slack, or your preferred project management tool.
Automatic capture triggers when JavaScript errors occur, while manual capture (Ctrl+Shift+S or Cmd+Shift+S) lets you capture context for any UI issue or workflow problem, even when no errors are detected.
Yes, TestScout provides granular controls over what data gets captured. You can enable/disable specific data types, configure console log limits, and set domain-specific rules to match your debugging needs.
The free plan allows 5 captures per day across 3 domains. Paid plans offer unlimited captures. TestScout automatically rotates stored captures to prevent browser storage issues, keeping the most recent 50 captures by default.
Free users get community support through our documentation and forums. Pro users get priority email support, and Enterprise customers get dedicated support with SLA guarantees. We also provide comprehensive documentation and video tutorials.
