Selenium Grid Setup Options
Grid 4 gives you choice in setup:
Standalone – All-in-one
Distributed – Separate components
Docker – Containerized
Let‘s look at examples of each…
Standalone Mode
Easiest way to get started…
// Standalone mode code// Explain ports, verification steps
Distributed Mode
For maximum scale and flexibility…
// Distributed mode configuration codeThis decouples the components across processes and machines.
