||mock-idp.js is a naive IdP that provides absolutely no
security for authentication. It can generate identity
assertion for whatever identity that is requested.
mock-idp.js validates identity assertion by simply decoding
the JSON and return whatever that is inside, with no integrity
protection and thus can be spoofed by anyone.
While being not practical at all, mock-idp.js allows us
to test various aspects of the identity API and allow tests
to manipulate the IdP at will.
