How to call passport.authenticate so that it will always be true

[manuel114]

Hello, im trying to call passport.authenticate with the mockstrategy in a unit test so that I will be able to call a function that currently checks for req.user (normally it would get it through a cookie).

I have used:
const passportMock = createMockPassport(app);
setupSerializeAndDeserialize(passportMock, null, null);
connectPassport(app, passportMock);

But I don't really know what to call on my test so that the authentification of a custom user object will be succesful and req.login(user) is called.

Thank you in advanced!
