🌉Selenium Grid
What is the Selenium Grid?
Selenium Grid 😎 allows running Selenium tests in parallel across multiple machines.
Why use Selenium Grid?
Some reasons to use Selenium Grid are:
✅ Speed up test execution time by running tests in parallel 🏃♀️🏃♂️
✅ Access different OSes, browsers, and browser versions not available locally 🖥️🌐
✅ Scale tests to handle large test suites 📈
✅ Distribute load to avoid overloading a single machine ⚖️
How does Selenium Grid work?
Selenium Grid has two main components:
Hub 🕸 - Manages and distributes tests to Nodes
Nodes 📱 - Executes the tests assigned by the Hub
Tests are sent to the Hub, which then distributes them to available Nodes for execution.📲
Interviewer: Can you give steps to use Selenium Grid?
Me: The basic steps are:
1.💡 Install the Selenium Server standalone jar
⚙️ Start the Hub
🚀 Start Nodes and register them with the Hub
👓 Configure the Nodes (browser, version, OS, etc.)
😎 Send tests to the Hub which distributes to Nodes for execution
