Selenium Grid Plugin [hot]

We implemented grid-monitor-plugin with:

Automation Testing Insider 5m Show all Hub & Node Architecture: A central hub acts as a control point, receiving test requests and routing them to several nodes (remote machines) that execute the actual browser interactions. Parallelism: Drastically reduces total runtime by executing large test suites simultaneously across multiple machines. Cross-Platform Coverage: Enables testing of a single application across multiple operating systems (Windows, macOS, Ubuntu) and browser versions (Chrome, Firefox, Edge) simultaneously. Scaling with KEDA/Kubernetes: Modern implementations often use tools like selenium grid plugin

| Metric | Without Plugin | With Plugin | Overhead | |--------|----------------|-------------|-----------| | Avg. session duration | 12.3 sec | 13.2 sec | +7.3% | | CPU (Router) | 18% | 21% | +3% | | Memory (Router) | 512 MB | 584 MB | +14% | | Command throughput | 450 cmd/sec | 422 cmd/sec | -6.2% | dynamic node provisioning via Docker

: A popular extension that provides a flexible, container-based Selenium Grid. It adds critical "missing" features like video recording , a live dashboard, and basic authentication. dynamic node management

Selenium Grid enables distributed test execution across multiple browsers and platforms. However, its native capabilities lack extensibility for custom reporting, dynamic node management, authentication, and advanced load balancing. This paper presents a for Selenium Grid 4, allowing third-party plugins to inject custom logic at key lifecycle events. We implement a reference plugin that adds real-time test monitoring, dynamic node provisioning via Docker, and a custom dashboard. Evaluation shows minimal performance overhead (≤8%) and significant improvements in scalability and observability.
