An important concept in computer programming and designing web applications is to perform effective testing that provides the information necessary to finalize the design and reduce its problems. One of the best tools for this purpose is Selenium, an excellent software testing framework. Selenium Grid is a key component of this platform. Here, we describe some of its important aspects, to help you understand its testing prowess.
What is Selenium Grid?
Selenium Grid is the portable server that empowers the testing on remote machines by using various web browser instances. The Grid works as the hub to connect the tests that are being conducted on different machines. Each testing phase occurs by first contacting the Grid to obtain each instance’s information. The hub in return delivers a WebDriver node to each test request and ensures that the process carries out without any issue.
Selenium Grid follows a Hub and Nodes architecture. It employs the setting of a central hub that must be placed on a unique machine. This machine can have any configuration and will provide the base for all application tests. There can be any number of computers that can play the role of the nodes, and they can have any configuration of hardware, operating systems and web browsers.
Selenium Grid can either be setup from the command line, indicating the hub and node information or started using a JSON configuration file. The Grid operation runs by using an available port on the nodal web browser to carry out the required testing operation.
Selenium Grid is a server solution that distributes the load of browser application testing to several remote machines that are available. This decreases the strain on singular hardware components and also ensures that the application is tested on all types of platforms and operating systems. This power to use different operating systems and browsers is excellent, because it is not possible to perform this activity on a single platform.
Selenium Grid offers the advantage of managing the entire testing process from a single, central node. The different configurations and browser versions can all be managed by creating policies on the Grid, rather than setting up individual tests to carry out application diagnosis on different platforms. The tests can all run in parallel, with the Grid able to coordinate the different machines and browser settings to generate the required results.
Selenium Grid is an excellent tool, as it saves time during the testing process. It is important that you test out any browser/hardware combination that your web application may face, during its operations and use by the consumers. The performance of the whole Selenium Suite enhances considerably, especially with the use of Grid 2.
Time saving is possible because multiple tests are running at the same time, without any conflict of interest. The details of these tests are then recorded in Selenium, which gives application developers all the information that they need to identify problem areas and make the necessary changes.
Selenium Grid is certainly an excellent tool, when it comes to testing your Java-based web applications. It simplifies the testing process and allows developers to carry out the testing phase in an effective manner, with improved precision and accuracy.
