CAS Login not testable with cypress

[p-a-s-c-a-l]

Upon login, CAS redirects to a different domain. Automatic redirect fails with:

Refused to display 'https://csis.myclimateservice.eu/' in a frame because it set 'X-Frame-Options' to 'sameorigin'

See also cypress-io/cypress#1506 and clarity-h2020/csis#122 (comment)

Manual redirect does not work either:

CypressError: cy.visit() failed because you are attempting to visit a second unique domain.
You may only visit a single unique domain per test.
Different subdomains are okay, but unique domains are not.
The previous domain you visited was: 'https://profile.myclimateservices.eu'
You're attempting to visit this new domain: 'https://csis.myclimateservice.eu'
You may need to restructure some of your code to prevent this from happening.

Sessions not preserved among different tests:

Visiting a different domain in another tests causes cypress to end up in an infinite loop:

Visiting a different domain in another tests causes cypress to end up in an infinite loop:

Probably related to missing ${baseUrl}, see cypress-io/cypress-documentation#1154 ?

However, setting ${baseUrl} to https://csis.myclimateservice.eu results in the following warning:

Cypress could not verify that this server is running:
https://csis.myclimateservice.eu
This server has been configured as your baseUrl, and tests will likely fail if it is not running.

Removing the baseUrl does not work. But visiting https://csis.myclimateservice.eu before https://profile.myclimateservices.eu does not lead to an infinite loop. ?!

• Setting the baseUrl programmatically instead of specifying it in cypress.json does not lead to to the 'Cypress could not verify that this server is running' error.
• baseUrl can only be specified once per project. So overwriting the baseUrl in 020 will also change the base url of the 010 test spec.
• Moving CSIS Tests to another specs file will still result in an infinite loop, too
