Welcome to this prologue to Selenium WebDriver. In the wake of perusing this guide, you will comprehend what Selenium Webdriver is, the means by which it works, and how to utilize WebDriver to robotize web testing.

Selenium WebDriver is a free, open-source system that gives a typical application programming interface (API) for program robotization. In a perfect world, current internet browsers should all render a web application similarly. Notwithstanding, every program has its own particular rendering motor and handles HTML a little in an unexpected way, which is the reason testing is expected to guarantee that an application performs reliably crosswise over programs and gadgets.

A similar program similarity issues that influence web applications could likewise influence mechanized web tests. In any case, robotized tests that utilization the Selenium customer API can keep running against any program with a WebDriver-dissension driver, including Chrome, Safari, Internet Explorer, Microsoft Edge, and Firefox.

Selenium WebDriver can keep running on Windows, Linux and macOS stages. Tests can be composed for Selenium WebDriver in any of the programming dialects bolstered by the Selenium venture, including Java, C#, Ruby, Python, and JavaScript. These programming dialects speak with Selenium WebDriver by calling strategies in the Selenium customer API.

Looking further: selenium training in Bangalore - For a programming dialect to work with Selenium, it must incorporate a library that sees either the momentum Selenium JSON Wire Protocol or the rising W3C WebDriver convention.

What programs can be tried with Selenium WebDriver?

Selenium WebDriver can automate tests for every famous program. Every program requires its own particular driver to speak with Selenium tests, as portrayed underneath. Extra data and download joins for the individual program drivers are accessible on the SeleniumHQ download page.

• Apple Safari-

Safari 10 gives local help to the WebDriver API, so there is no compelling reason to download a driver from the SeleniumHQ site. The Safari Driver can be propelled straightforwardly from the/usr/receptacle/safaridriver executable. Most Selenium dialect particular customer libraries will dispatch the Safari driver without extra arrangement.

• Google Chrome-

Dissimilar to Safari, running computerized tests on the Google Chrome program requires a different executable, the ChromeDriver. This executable is kept up by the Chromium group with help from Selenium WebDriver supporters, and is accessible for download from Google.

• HTMLUnit Headless Browser-

The HTMLUnit Headless Browser permits mechanized web tests to execute without stacking a graphical UI, which can fundamentally quicken testing.

• Web Explorer-

In spite of the fact that Microsoft presented the Edge program some time back, numerous Windows clients are as yet utilizing Internet Explorer, or have changed to another program, for example, Chrome. The Selenium venture gives the InternetExplorerDriver.

• Microsoft Edge-

The Microsoft Edge WebDriver is given by Microsoft to robotized web testing.

• Mozilla Firefox-

Testing Firefox program renditions 47.0.1 or more requires the Mozilla GeckoDriver. "Gecko" is the name of the internet browser rendering motor utilized as a part of FireFox and in addition other Mozilla applications, for example, the Thunderbird email customer.

How does Selenium WebDriver function?

Selenium WebDriver comprises of a dialect particular customer, a remote server, and program particular drivers. The Selenium WebDriver customer API presents a demand to the remote server, which advances it to a program particular driver, for example, the Chrome Driver or the Safari Driver. The program driver dispatches the program to play out the activity, and afterward restores a reaction to the customer. A rundown of WebDriver summons can be found on the Mozilla designer website.

To play out an activity, for example, entering information in a field or clicking a catch, a customer ask for must locate the specific GUI component that is the objective of the activity. Selenium can utilize a few different ways to find a component, including traits, for example, the component ID, name, XPath, connect content, or CSS selector. The best locator to utilize is one that is steady and exceptional to the web component. While the component's ID regularly meets these necessities, know that Selenium courses in Bangalore some web components have dynamic IDs that change each time the page loads. Components with dynamic IDs require an alternate locator technique, for example, CSS selector or XPath. Creating extraordinary and stable locators can be troublesome and tedious.

Why utilize Selenium WebDriver for web testing?


• Selenium Webdriver is free and open-source
• The Selenium venture is advanced by pioneers in the web improvement and programming testing businesses
• It will bolster the rising W3C WebDriver standard
• It offers the capacity to run tests in parallel utilizing Selenium Grids


• Selenium Webdriver is intricate to introduce and arrange
• Building computerized tests requires propelled programming information, particularly since there is no catch and-replay usefulness
• The Selenium IDE never again works in Firefox adaptation 55 and later, because of changes in the Firefox program.
• There is no worked in test comes about detailing usefulness
