    FAQs

    Everything you want to know about the Browser Testing

    What is Browser Testing?

    Browser testing is the process of verifying that a website or web application functions correctly, appears consistent, and performs optimally across different browsers, browser versions, devices (desktop, mobile, tablet), and operating systems. It ensures users have a seamless experience regardless of how they access your application.

    What features are analyzed in a browser test?

    The middleware platform checks the following features during browser testing:

    • Functionality: Forms, buttons, navigation, and interactive elements.
    • Visual Consistency: Layout, CSS rendering, fonts, and responsive design.
    • Performance: Page load times, resource usage (CPU/memory), and JavaScript execution.
    • Compatibility: Support for browser-specific features.
    • Accessibility: Compliance with WCAG standards (e.g., screen reader compatibility).
    How does Middleware Browser Testing enable faster troubleshooting?

    Middleware tracks core web vitals (e.g., load times, LCP, CLS) in real-time and correlates browser-side issues (e.g., JavaScript errors) with backend traces (APIs, databases). This unified view helps pinpoint root causes, such as slow API responses impacting page rendering, and reducing troubleshooting time.

    How does session replay help improve user experience for browser testing?

    Session recordings capture user interactions (clicks, scrolls, errors) alongside performance data (core web vitals). This helps you:

    • Replicate bugs reported by users.
    • Analyze rage clicks or high drop-off points.
    • Validate UI behavior across browsers.
    Can I monitor the impact of new deployments on browser performance?

    Yes! Middleware lets you trace error rates and performance metrics post-deployment. Compare pre and post-release data to detect regressions and ensure updates don’t harm user experience.

    Can I set alerts for critical front-end issues on browser testing?

    Yes. Configure custom alerts for metrics like error spikes, slow page loads, or feature-flag failures. Middleware sends notifications via email, Slack, or integrations like PagerDuty, letting you fix issues before they escalate.
