Using Selenium Webdrivers to Browse Pages with Minimal Resource Loading

I'm attempting to restrict Javascript from altering the source code of the site while testing with Selenium. Disabling Javascript completely in the Webdriver is not an option as I require it for testing purposes. Below is my approach for the Firefox Webdriver:

        firefoxProfile.setPreference("permissions.default.image", 2);
        firefoxProfile.setPreference("permissions.default.script", 2);
        firefoxProfile.setPreference("permissions.default.stylesheet", 2);
        firefoxProfile.setPreference("permissions.default.subdocument", 2);

I have disabled Images, Scripts, and Stylesheets in Firefox. Is there a way to achieve this with the Internet Explorer Webdriver and Chrome Webdriver as well? I haven't come across similar preferences for these browsers. Alternatively, is there a more elegant method to prevent the webdrivers from loading JS Files on the site? Thank you!

Answer №1

To resolve this issue, the recommended solution is to utilize a proxy. A great option for integrating WebDriver with a proxy is browsermob proxy, which can be found at: 

public WebDriver initializeBrowser() throws Exception {
    ProxyServer server = new ProxyServer(proxy_port); // Import from net.lightbody.bmp.proxy

    server.start();
    server.setCaptureHeaders(true);
    
    // Blacklisting google analytics requests
    server.blacklistRequests("https?://.*\\.google-analytics\\.com/.*", 410);

    // Whitelisting necessary requests
    server.whitelistRequests("https?://*.*.yoursite.com/.*, https://*.*.someOtherYourSite.*".split(","), 200);

    Proxy proxy = server.seleniumProxy(); // Proxy package from org.openqa.selenium.Proxy

    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.PROXY, proxy);

    Webdriver driver = new FirefoxDriver(capabilities); // Initialization of Firefox driver
    //WebDriver driver = new InternetExplorerDriver(); // Alternative initialization for Internet Explorer

    return driver;
}

To achieve your desired result in a consistent manner across all browsers, consider utilizing a proxy. With this approach, you can intercept resource requests and prevent them from loading. This method offers the benefit of using a single code base for all browsers, rather than having to create specific settings for each individual browser.
