Disable CORS restriction

A guide to disabling CORS restriction for running tests on Safari browsers in BrowserStack Automate.

In this guide, you will learn:

What is CORS?

Cross-Origin Resource Sharing (CORS) is a mechanism that enables web pages to access resources running on a restricted or different domain. BrowserStack provides the disableCorsRestrictions capability to disable CORS restrictions on the Safari browser.

Using the disableCorsRestrictions capability in your test script enables your publicly available or locally-hosted website to access resources from another domain, server, or APIs.

Disabling CORS restriction may cause security issues in your website under test. Use this capability only after careful consideration.

Sample screenshots with and without CORS restriction

The following sample screenshots show the content of https://polar-inlet-22085.herokuapp.com with and without CORS restriction disabled:

Due to CORS restriction, https://polar-inlet-22085.herokuapp.com fails to fetch content from another domain on its page.

With CORS restriction

After the CORS restrictions are disabled, https://polar-inlet-22085.herokuapp.com is able to fetch content from another domain.

Without CORS restriction

Supported versions

The following table provides a list of supported browsers and OS platforms where you can use the disableCorsRestrictions capability.

Browser/OS Supported versions
Safari browser v12 and above
macOS platform Sonoma, Ventura, Monterey, Big Sur, Catalina, and Mojave

Set the capability

If you are using BrowserStack SDK, you can set the following capabilities in the browserstack.yml file:

Capability Description Expected values
disableCorsRestrictions Disable CORS restrictions in the Safari browser, which is enabled by default. true: Disables CORS restriction
false(default): Enables CORS restriction

Example test script

In the following example test script, we run a sample test that disables CORS restriction, opens https://polar-inlet-22085.herokuapp.com on Safari browser, and prints screenshot of the web page in the Text Logs section of the Automate session dashboard:

BrowserStack SDK is a plug-n-play solution that takes care of all the integration steps for you. Using the BrowserStack SDK is the recommended integration method for your project. To know more, visit the SDK core concepts page.

The following table provides information about the disableCorsRestrictions capability:

Capability Description Expected values
disableCorsRestrictions Disable CORS restrictions in the Safari browser, which is enabled by default. true: Disables CORS restriction
false(default): Enables CORS restriction

Use the following sample code snippets to set the disableCorsRestrictions capability to true in your test script:

DesiredCapabilities capabilities = new DesiredCapabilities();
HashMap<String, Object> browserstackOptions = new HashMap<String, Object>();
browserstackOptions.put("disableCorsRestrictions", "true");
capabilities.setCapability("bstack:options", browserstackOptions);
var capabilities = {

}

The following table provides information about the browserstack.disableCorsRestrictions capability:

Capability Description Expected values
browserstack.disableCorsRestrictions Disable CORS restrictions in the Safari browser, which is enabled by default. true: Disables CORS restriction
