Is there way to disable CORS check using RemoteWebDriver for SauceLabs

Question

Question says it all, I m trying to execute some selenium tests on SauceLabs, the test loads a webpage that makes a cross domain request. I was thinking is there a way to disable CORS, in platform-independent way through code.

On a server you control? Yes-set the appropriate headers. On a server you don’t control? Trust would defeat the purpose. You could set up a proxy so you’re not making Ajax requests, although you might have to play some games, and it still might not work. — Dave Newton, Nov 29 '19 at 12:11

While using ChromeDriver / Chrome combo to disable cors check you can use the --disable-web-security argument.

which is defined in content_switches.cc as:

// Don't enforce the same-origin policy. (Used by people testing their sites.)
const char kDisableWebSecurity[]            = "disable-web-security";

Code samples:

Windows:

ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-web-security"); // don't enforce the same-origin policy
options.addArguments("--disable-gpu"); // applicable to windows os only
options.addArguments("--user-data-dir=~/chromeTemp"); // applicable to windows os only
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");

OSX:

ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-web-security"); // don't enforce the same-origin policy
options.addArguments("--user-data-dir=/tmp/chrome_dev_test");
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");

Linux

ChromeOptions options = new ChromeOptions();
options.addArguments("--disable-web-security"); // don't enforce the same-origin policy
WebDriver driver = new ChromeDriver(options);
driver.get("https://google.com");

Note: If you need access to local files for development/testing purposes like AJAX or JSON, you can use -–allow-file-access-from-files flag.
