@kisztof we also need to makes sure that it works on the integration level. We can change a bit UrlAliasLookupTest to accept data provider which defines URL Alias name schema, input names, and expected URL Alias. createFolder would have to be replaced by some custom Content Type so you can set URL Alias name schema.
Alternatively instead of lookup the test can simply load system (auto-generated) URL Aliases and check if the path is correct.

Can be done as a follow-up to speed up QA on this PR.
