How to check for this condition of login and logout err != null

[dhyanaswain]

How to test the below condition

sp.create_login_request_url(idp, {}, function (err, login_url, request_id) {
if (err != null){
failure(500);
}

Same for the log out function
sp.create_logout_request_url(....)

Its always sending the err = null.

Need help, writing the Jest test cases for the code!

It seems that for test cases, we specify options to define assert_endpoint: https://github.com/Clever/saml2/blob/master/test/saml2.coffee#L1033.

Can you try to do the same?
