Working with Selenium Grid
Explore how Selenium Grid works to distribute Selenium WebDriver tests across multiple nodes for parallel execution. Understand the hub-node architecture, how to start and configure the grid, and the common limitations such as complexity, limited control, feedback delay, and lack of automatic test reruns. This lesson equips you to implement parallel testing and recognize challenges in Selenium Grid setups.
We'll cover the following...
Selenium Grid
There is another tool that comes built into the Selenium Standalone Server called the Selenium Grid. Selenium Grid allows running the Selenium tests in parallel to cut down the execution time. Its structure consists of two parts:
- One hub
- Many nodes
Selenium grid hub
The hub receives the test requests and distributes them to the nodes.
Selenium grid node
A node gets tests from the hub and runs them.
We can run the Selenium tests in parallel by following the below step:
- Start the Hub:
