I'm just adding some thoughts as I read through this - this seems like something that is easily handled by playwright, ie

• go to page
• don't log in
• expect the URL to have been redirected

we will most likely have tests like this that cover this expected behavior, i think im just feeling a little dumb on what a unit test might actually "mean". i always thought of unit tests as testing 1 thing and 1 thing only

i also wonder a lot about mocking, if we are mocking these objects to be exactly what we want - are these good representations of how the actual components/clerk objects might be working?

just thinking out loud here, but there will be some duplicated tests i imagine at some point, maybe thats totally fine though?
