Selenium Grid is used to speed up the execution by using multiple machines (multiple browsers with different versions, and browsers running on different operating systems) and run tests in parallel. And also to reduce the time spent for running the test suite after developers check-in their code.
In this article, will talk about CrossBrowserTesting which lets us to test website across 1500+ browsers - Android devices, iPhones, iPads, Windows, & OSX. Check list of Operating systems, mobile devices and browsers supported by CrossBrowsersTesting.
BrowserMob Proxy is an open source tools which is used to capture performance data for a web applications in an HAR format. It also allows to manipulate browser behavior and traffic, such as simulating network traffic, rewriting HTTP requests and responses etc.
In the previous article, we have seen launching Firefox browser with Gecko driver using Selenium 3. Now let us try to launch Microsoft Edge browse using Selenium 3.
Before proceeding, to start using Webdriver with Microsoft Edge browser, make sure you have Windows 10 on your machine and download the specified Microsoft WebDriver server version for your build.
The first example that we will look into is launching firefox using the Geckodriver. When using Selenium 3 , you have to download geckodriver. Just like the other drivers available to Selenium, Mozilla has released geckodriver executable that will run alongside the browser.
You can download the latest executable on the GitHub page. Now you need to specify the system property with the path
Selenium Page Factory Pattern is like an extension to Page Object Model , but Page Factory is much enhanced model. To start with, we just need to import package ‘org.openqa.selenium.support.PageFactory’
"Factory class can be used to make using Page Objects simpler and easier".
In previous article we have seen configuring selenium grid and execute a simple test on firefox browser. In this tutorial we will see 'Parallel execution of tests' using selenium grid and execute tests on firefox and chrome browser.
We will register multiple nodes to the Hub and execute tests in parallel. In the below example we will register a node in the same local machine where hub is running and other node in remote machine.
Selenium Grid allows us to execute our tests in multiple machines (physical / virtual) and multiple browsers with different versions, which dramatically speeds up test execution and helps in reducing total amount of time required for test execution.
For example, if we have a script that takes 100 minutes to execute sequentially , we could break that down to 10 short tests script run across 10 machines, and can complete them in 10 minutes without copying your test code to the other machine.
