How to stub liana.ensureAuthenticated?

[neokaiyuan]

Expected behavior

sinon.stub(liana, 'ensureAuthenticated') should stub the ensureAuthenticated

Actual behavior

stub does not address liana 'ensureAuthenticated', and code in forest-express-sequelize and forest-express seem to obscure how ensureAuthenticated is exposed

Context

I use liana.ensureAuthenticated as a middleware as suggested by Forest docs https://doc.forestadmin.com/developer-guide/express-sequelize.html#uploading-images and am hoping to unit test my controller.

seems to be a broader issue with stubbing express app middleware before app gets loaded.

ended up resolving this by not including ensureAuthenticated middleware in test env, as bad as it is to include test-specific logic in production code.

Could you provide your working example?
