[Grok-dev] How does one unittest a view?

[Santiago Videla]

Hi Wichert,

I don't understand why you would unittest a View. Could you give some
examples of use case? I do understand the idea of `test things in isolation`
but I don't understand what `things in a view` would you like to `test in
isolation`

I mean, if you have some methods in a View, but this methods doesn't need
the request instance at all (that seems from the tests examples you posted),
why don't write that methods in the Model or in some Utility and write
unittest for those

My apologies for give you more questions instead of answers... :)

Best Regards
