I am trying to setup Cypress.io to run tests as a local Windows user against a .NET Core web application that uses Windows Authentication. I can achieve this manually by opening the web browser to run as the local user, so I know the authentication is working. However, I'm still getting 401 when I try to run a simple test. I have successfully installed both cypress and cypress-ntlm plugin. I open Cypress using the command npx cypress-ntlm open. My test code is: describe('visit site', () => { it('passes', () => { cy.ntlm(['localhost:7136'], 'username', 'password'); cy.visit('https://localhost:7136/') }) }) What configuration/setup am I missing?
