Introduction to Selenium Grid
Hello everybody. After a long hiatus, I decided to continue blogging. Recently, I started to research the topics of parallel testing, test runs in different environments, which I was curious about and started working on.
In this article, I will tell you a little bit about Selenium Grid. If you’re ready, let’s start.
What is Selenium Grid?
- It is a structure that allows us to run multiple tests on different browsers, operating systems, devices.
- It allows us to run our tests on different browsers in different operating systems by scaling.
- It also allows us to save time during test runs.
Why do we need Selenium Grid?
Selenium Grid runs server and environment very fast. It speeds up our tests by using multiple machines in a virtual environment to run our tests in parallel and allows us to get fast results.
As a result, we need to run your tests against multiple browsers, multiple versions of the browser, and browsers running on different operating systems.
Selenium Grid Architecture
Selenium Grid consists of hubs and nodes. There is only one hub on the server. Can host multiple nodes. The hub receives information about the desired browser, browser version and operating system where the test should be executed, and directs the tests to the supporting machine that provides them, namely the node.
I hope this much information is enough as an introduction for now. As I make progress, I will continue my articles with project examples. Take good care of yourself for now..:)
