WebDriver drives a browser natively, learn more about it.

WebDriver drives a browser natively, as a user would, either locally or on a remote machine using the Selenium server, marks a leap forward in terms of browser automation.

Selenium WebDriver refers to both the language bindings and the implementations of the individual browser controlling code. This is commonly referred to as just WebDriver.

Selenium WebDriver is a W3C Recommendation

• WebDriver is designed as a simple and more concise programming interface.

• WebDriver is a compact object-oriented API.

• It drives the browser effectively.

Getting started

If you are new to Selenium, we have a few resources that can help you get up to speed right away.

Driver Sessions

 

Supported Browsers

 

Waits

 

Web elements

Identifying and working with element objects in the DOM.

Browser interactions

 

Actions API

A low-level interface for providing virtualized device input actions to the web browser.

BiDirectional functionality

 

Support features

Support classes provide optional higher level features.

Troubleshooting Assistance

How to get manage WebDriver problems.

 

Install a Selenium library | Selenium

Setting up the Selenium library for your favourite programming language.

First you need to install the Selenium bindings for your automation project. The installation process for libraries depends on the language you choose to use. Make sure you check the Selenium downloads page to make sure you are using the latest version

A list of all supported frameworks for each version of Selenium is available on Nuget

There are a few options for installing Selenium.

Packet Manager

Install-Package Selenium.WebDriver

 

Install browser drivers | Selenium

Install browser drivers

Setting up your system to allow a browser to be automated.

Through WebDriver, Selenium supports all major browsers on the market such as Chrome/Chromium, Firefox, Internet Explorer, Edge, and Safari. Where possible, WebDriver drives the browser using the browser’s built-in support for automation.

Since all the driver implementations except for Internet Explorer are provided by the browser vendors themselves, they are not included in the standard Selenium distribution. This section explains the basic requirements for getting started with the different browsers.

Read about more advanced options for starting a driver in our driver configuration documentation.

 

1. Selenium Manager (Beta)

Selenium v4.6

Selenium Manager helps you to get a working environment to run Selenium out of the box. Beta 1 of Selenium Manager will configure the drivers for Chrome, Firefox, and Edge if they are not found on the PATH. No extra configuration is needed. Future releases of Selenium Manager will eventually even download browsers if necessary.

Read more at the blog announcement for Selenium Manager .

2. Driver Management Software

Most machines automatically update the browser, but the driver does not. To make sure you get the correct driver for your browser, there are many third party libraries to assist you.

Important: This package does not currently work for IEDriverServer v4+

1. Import WebDriver Manager Package 这个对应的github源码是，GitHub - rosolko/WebDriverManager.Net: Automatic Selenium Webdriver binaries management for .Net

nuget安装包是https://www.nuget.org/packages/WebDriverManager/

Install-Package WebDriverManager

using WebDriverManager;
using WebDriverManager.DriverConfigs.Impl;

Copy

2. Use the SetUpDriver() which requires a config class:

            new DriverManager().SetUpDriver(new ChromeConfig());

            var driver = new ChromeDriver();

 

3. The PATH Environment Variable

This option first requires manually downloading the driver (See Quick Reference Section for links).

This is a flexible option to change location of drivers without having to update your code, and will work on multiple machines without requiring that each machine put the drivers in the same place.

You can either place the drivers in a directory that is already listed in PATH, or you can place them in a directory and add it to PATH.

To see what directories are already on PATH, open a Command Prompt and execute:

echo %PATH%

 

If the location to your driver is not already in a directory listed, you can add a new directory to PATH:

setx PATH "%PATH%;C:\WebDriver\bin"

 

You can test if it has been added correctly by starting the driver:

chromedriver.exe

 

4. Hard Coded Location

Similar to Option 3 above, you need to manually download the driver (See Quick Reference Section for links). Specifying the location in the code itself has the advantage of not needing to figure out Environment Variables on your system, but has the drawback of making the code much less flexible.

var driver = new ChromeDriver(@"C:\WebDriver\bin");
