Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Discover the principles of visual regression testing to capture pixel-perfect snapshots of your interfaces, install Node.js and BackstopJS in a dedicated development environment, create your first baselines from a real website, perform manual comparative tests to identify visual discrepancies, and produce an initial report with annotated screenshots, while learning to avoid common pitfalls for reliable results from day one.
Dive into BackstopJS to automate your first visual tests on React or Vue.js applications, configure multiple viewports for desktop and mobile, define smart CSS selectors to isolate critical components, run test suites on real business cases like an e-commerce site, analyze generated diffs with built-in tools, adjust tolerance thresholds to minimize false positives, and integrate a practical exercise on your personal project with live trainer feedback.
Integrate visual regression testing into real CI/CD pipelines with GitHub Actions and Jenkins, set up automatic triggers on pull requests to validate UI changes, test on dynamic staging environments, manage manual approvals for new baselines via collaborative interfaces, simulate continuous deployments with Docker for reproducibility, produce Slack/Teams notifiable reports, and apply all this to a business red thread project to measure impact on release velocity.
Move to Percy and Applitools for collaborative visual diff analysis, learn to classify anomalies as bugs, accepted changes, or ignored, test on multiple browsers with Chrome/Firefox/Safari emulators, optimize masks for dynamic elements like sliders or modals, conduct simulated team reviews with shared annotations, generate custom dashboards to track UI stability metrics, and validate your skills on real cases of costly production regressions.
Prepare your skills for 2026 by optimizing large-scale visual regression testing suites, integrate AI for automatic minor change detection, set up post-deployment monitoring with proactive alerts, test on real devices via cloud services like BrowserStack, finalize your red thread project with an executive report and action plan for the company, review best practices to reduce flakiness to under 5%, and leave with a concrete portfolio demonstrating your certified expertise.
The Training Visual Regression Testing - Detect UI Regressions in 2026 program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.
The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
