How do I get a self signed local domain be trusted in Cypress?

I want to get self signed local domain be trusted in Cypress

Why is this needed?

I am developing over https on localhost manually, and with mkcert help chrome accept certificate as trusted.
Common approach in Cypress is some manual testing after test finishes, so it will be nice to have local certificate trusted in Cypress too.

Hi @TimPchelintsev, Cypress intercepts HTTPS traffic for its core functionality, so there is currently no way to do this. More information: https://docs.cypress.io/faq/questions/using-cypress-faq#Is-there-a-way-to-give-a-proper-SSL-certificate-to-your-proxy-so-the-page-doesnt-show-up-as-not-secure

this definitely seems possible. mkcert creates a CA key at ~/.local/share/mkcert/rootCA-key.pem and adds the corresponding cert to the system's trust store (/etc/ssl/certs/ on linux). all cypress needs to do is use that CA to sign the certs it generates at

return path.join(this.keysFolder, 'ca.private.key')
