You'll probably use `send_data` inside your controller action. It'll set a
Content-Type header, so check for that.
No need to couple yourself to the implementation, check files on disk, etc. Try
and check what the action is supposed to do, not that it's done half the job.
test 'should export a CSV file' do
# appropriate setup to create a collection_of_stuff
get :export, appropriate: params, go: here
assert 'text/csv', response.header['Content-Type']
rows = CSV.parse(response.body)
assert_equal collection_of_stuff.size, rows.size
assert_equal 'Contents of column 1', rows.first[0]
end
Don't get too rigid with what your asserts check for; I'd just check that it
looked like the right kind of data was in it (i.e. number of rows, and probably
just that the right stuff was in the first column; detailed testing of what's
in the CSV is something I'd only unit test at the model level, and only then if
it was complicated [i.e. only if I was likely to get it wrong without testing
it]).
