There are two ways to implement CSP:
<meta> tag implementation is fully supported by Cypress without any
configuration required. This is because Cypress loads the necessary
tags into your application before any
<meta> tag is parsed. This prevents any
CSP directives from being applied to the script loaded by Cypress.
The second implementation requires you to configure Cypress to allow the headers to be sent to your application. By default, Cypress will remove any CSP headers from the response before it is sent to the browser. This is done to prevent Cypress from being blocked by the browser's CSP implementation.
For most application tests, this should not cause any issues. However, if you
are testing your application's CSP implementation, you will need to configure
Cypress to allow the headers to be sent to the browser. You can do this by
