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:
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:
