The Selenium Grid is a testing tool which permits us to run our tests on different machines against different browsers. It is a part of the Selenium Suite which specialise in running multiple tests throughout different browsers, operating system and machines. You can link to it with Selenium Remote by defining the browser, browser variation, and operating system you desire. You specify these values through Selenium Remote’s Capabilities.
Selenium Grid improves the turnaround time of the test results. It is particularly beneficial when the test suite is big and takes more time to run. It offers flexibility and expands test protection within a minimal time. Given that the virtual facilities remains in usage, upkeep becomes simple.
With Selenium Grid you can develop a network of connected test machines (also called nodes). This network of test machines is controlled by a Hub, using which you can run your tests on different connected nodes. Each node is essentially a computer (even a virtual machine) with a combination of Operating system and Browsers. This allows us to create a network of test machines with differing combinations of Operating system and web browsers. Utilizing Selenium Grid you can run tests on a range of Operating System and Browser mixes. Lets understand Selenium Grid in more details listed below.
However, adding features to applications includes its own set of difficulties on companies seeking to provide much better software in record time. Automating processes has ended up being a natural next action. Automation Testing is critical in making software release faster and bug-free. According to this report, the worldwide automation testing market size is anticipated to grow from USD 12.6 billion in 2019 to USD 28.8 billion by 2024.
Selenium is a structure of automation testing tools, based upon the JavaScript framework. Automated Selenium testing is considerably favoured by QAs for replicating end-user actions on websites to monitor their behaviour. It drives the interactions that occur on the target websites and might run them automatically, without requiring manual inputs.
It supports distributed test execution. At first, you have a local machine where you compose the test cases and performs on the same machine. However, in a huge organization, you have multiple test cases, and it’s not possible to run all the test cases in the same machine. In a large company, you have multiple servers, so local machine disperses the test cases across different machines/servers.
In Selenium Grid, the hub is a computer system which is the main point where we can fill our tests into. Hub also functions as a server because of which it acts as a central indicate control the network of Test machines. The Selenium Grid has only one hub and it is the master of the network. When a test with given DesiredCapabilities is offered to Hub, the Hub look for the node witch matches the given configuration. For instance, you can state that you want to run the test on Windows 10 and on Chrome browser with verision XXX. Hub will search for a machine in the Grid which matches the criterion and will run the test on that Machine. If there is no match, then hub returns an error. There need to be only one hub in a Grid.
Selenium Grid is a clever proxy server that makes it simple to run tests in parallel on multiple machines. This is done by routing commands to remote web browser circumstances, where one server acts as the hub. This hub paths test commands that remain in JSON format to multiple signed up Grid nodes.
Automation testing has not only improved delivery timelines however also ensured an enhanced scale of testing. With this method, organizations can deliver software more effectively. From a technical point of view, this is done by carrying out cross browser compatibility tests by covering a set of different browsers, devices, and tools as a part of the testing procedure.
Frequently including new functions to existing products has helped business drive engagement on their applications. For instance, PubG added features like newer maps, gameplay enhancements to drive more new users. Even Tesla prepares to add Netflix and YouTube streaming abilities in their cars quickly.
Selenium Grid is a feature in Selenium that enables you to run test cases in different machines across different platforms. The control of triggering the test cases is on the regional machine, and when the test cases are activated, they are immediately performed by the remote machine. Expect you have 5 test cases. Your regional machine is running multiple applications, so you want to run your test cases in a remote machine. You require to configure the remote server so that the test cases can be carried out there.
Selenium Grid is a part of the Selenium Suite that focuses on running multiple tests throughout different browsers, operating systems, and machines in parallel. It is attained by routing the commands of remote web browser circumstances where a server acts as a hub. A user needs to set up the remote server in order to carry out the tests.
From creating test cases to executing them, automation testing is typically a lengthy procedure. This is specifically passing away due to a great deal of browser versions, operating systems, and devices tests need to be run on. Selenium Grid, a part of Selenium, makes this easier by using concurrent execution of tests.
