Selenium Components
Selenium has been in the industry for a long time and is used by automation testers all around the globe.
Let’s check the four major components of Selenium
Selenium IDE
Selenium IDE (Integrated Development Environment) is the major tool in the Selenium Suite. It is a complete integrated development environment (IDE) for Selenium tests. It is implemented as a Firefox Add-On and as a Chrome Extension. It allows for recording, editing, and debugging of functional tests. It was previously known as Selenium Recorder.
Selenium RC (Remote control)
Selenium Remote Control (RC) is a server, written in Java, that accepts commands for the browser via HTTP. RC makes it possible to write automated tests for a web application in any programming language, which allows for better integration of Selenium in existing unit test frameworks. To make writing tests easier, the Selenium project currently provides client drivers for PHP, Python, Ruby, .NET, Perl, and Java. The Java driver can also be used with JavaScript (via the Rhino engine).
Selenium Web Driver
Selenium WebDriver is the successor to Selenium RC. Selenium WebDriver accepts commands (sent in Selenese, or via a Client API) and sends them to a browser. This is implemented through a browser-specific browser driver, which sends commands to a browser and retrieves results. Most browser drivers launch and access a browser application (such as Firefox, Google Chrome, Internet Explorer, Safari, or Microsoft Edge); there is also an HtmlUnit browser driver, which simulates a browser using the headless browser HtmlUnit. Selenium WebDriver does not need a special server to execute tests.
Selenium GRID
Selenium Grid is a server that allows tests to use web browser instances running on remote machines. With Selenium Grid, one server acts as the hub. Tests contact the hub to obtain access to browser instances. The hub has a list of servers that provide access to browser instances (WebDriver nodes) and lets tests use these instances. Selenium Grid allows running tests in parallel on multiple machines and managing different browser versions and browser configurations centrally (instead of in each test). The ability to run tests on remote browser instances is useful to spread the load of testing across several machines and to run tests in browsers running on different platforms or operating systems.
Now lets move to our Selenium WebDriver Tutorial.
Selenium WebDriver Tutorial | Working, Benefits and Limitations
Selenium WebDriver is one of the most important part of of the Selenium test suite and this Selenium WebDrive Tutorial will provide you with the answer to why it is the most important Selenium suite, along with all the basic concepts.
Selenium is an open-source program that automates web browsers. Selenium Webdriver is mainly used to execute the scripts according to the browser we are using. Selenium is a powerful tool for controlling web browsers through programs.
It is functional for all browsers, works on all major OS, and its scripts are written in various languages, i.e., Python, Java, C#, etc., we will be working with Python. Selenium has four major components Selenium IDE, Selenium RC, Selenium Web driver, and Selenium GRID.
