Our office network generally has a firewall for some categories of websites and we are restricted to open them. Due to their generic definition of firewall which restricts opening websites, sometimes it restricts to open the site where either we need to perform the automation task, or we actually need them for our project assistance.

So, these are the real-life scenarios which restrict to open websites. Even we sometimes add specific URLs in Advanced proxy settings. Our agenda for this tutorial is about the setting proxy at runtime through Selenium WebDriver. This can only be happening through capabilities settings which we have discussed in the last two articles. Proxy is the intermediary between your computer and other computers on the web. It acts as the mediator to forward the request to access the contents available at another computer or server.

There are several reasons for which we use a Proxy server. Some of the reasons are listed as follows:. We can set proxy either manually or through automation at runtime.

Open your Google Chrome browser then go to setting. Open proxy settings from the setting. You can type in the search box there. Then you see there is an option called LAN Setting, click on it then you get a new window where you find some fields to enter the details of the Proxy server.

Proxy servers are an invaluable tool for localization testing. For example, suppose that you run an ecommerce website and want to ensure that the proper language and currency appears for users from a certain country.

Or, you may operate a sports goods retailer and want to show certain promotions to certain states based on their home sports teams. Rather than assuming that things are showing properly, you can access the website as a user would from a target location. Quality assurance testers can see how the user experience looks, while test engineers can incorporate proxy servers into automated tests to verify functionality over time. Both of these approaches are critical to success.

Selenium is the most popular tool for browser automation. When writing automated tests, developers can use Selenium to test how a browser behaves without opening and running a full browser instance.

You ensure that everything is working without having to put in hundreds of hours of manual quality assurance testing! Many free proxy servers are unauthenticated, which means that a username and password are not required. In other cases, you may be able to whitelist your IP address on a premium proxy service, such as WonderProxyto avoid authentication. This is the best option for most development teams since it simplifies the setup and execution of integration tests.

The easiest way to integrate authenticated proxies with Selenium is by using PhantomJS as a headless browser instead of the Chrome WebDriver.

In order to do this, you must use Selenium 3. The good news is that the features are largely the same and it might be right for your situation. Note: evar retrieves environmental variables that are set with the username and password for the proxy. The second option is adding a browser extension that does the authentication for Selenium, as detailed on this Stack Overflow answer. While this approach is more complex, you can use it with the latest version of Selenium, which may be a requirement for some development teams.

The first step is creating a Chrome extension by including two files in an archive, named proxy. The example above only uses a single proxy server in the extension. If you'd like to add more proxy servers, you would need to make further modifications to the chrome.

The good news is that the setup process only needs to be done once and the tests should be easy to automate in the future. The bad news is that adding an extension to Chrome may add some time to the automated test process.First of all you need a proxy server.

Cris Mar 05, Yes, but in order to access that proxy, I think you need to authenticate.

Most of the time when we create any webdriver automation code using public websites like Google, Facebook, Yahoo… etc, which works very well at our home pc but not at office. This may have various reasons.

A proxy or proxy server is basically another computer which serves as a hub through which internet requests are processed. By connecting through one of these servers, your computer sends your requests to the proxy server which then processes your request and returns what you were wanting. In this way it serves as an intermediary between your home machine and the rest of the computers on the internet. Proxies are used for a number of reasons such as to filter web content, to go around restrictions such as parental blocks, to screen downloads and uploads and to provide anonymity when surfing the internet.

To work your browser under proxy you may need below settings.

Add that to your Firefox profile as below. The next step after loading the extension, is to actually set the preferences that we need to be set. For example below, I specify that I want 1 http header to be set, the header name, the header value which could be dynamically coming from some api call and then finally enabling the extension.

This allows the extension to be loaded when webdriver kicks of Firefox and sets it in the active mode along with the http header.

Currently I have proxy support using a proxy profile but is there a way to change the proxy when the browser is alive and running?

This is a slightly old question. But it is actually possible to change the proxies dynamically thru a " hacky way " I am going to use Selenium JS with Firefox but you can follow thru in the language you want. As far as I know there are only two ways to change the proxy setting, one via a profile which you are using and the other using the capabilities of a driver when you instantiate it as per here.

Sadly neither of these methods do what you want as they both happen before as you create your driver. I have to ask, why is it you want to change your proxy settings? The only solution I can esily think of is to point firefox to a proxy that you can change at runtime. I am not sure but that might be possible with browsermob-proxy. One possible solution is to close the webdriver instance and create it again after each operation by passing a new configuration in the browser profile.
