[Testing] Counting Records in Array from Query

rubyonrails-talk

I can’t seem to figure out how to assert in my test that my method which finds 5 records is in fact returning five records.

In my model:

app/models/widget.rb

… def self.recent_widgets find(:all,

     :conditions => "created_at <= now()",
     :limit => 5,
     :order => "created_at desc")

end

I created a widgets.yml fixture with five records in it.

In my test_widget.rb unit test I want to assert that there are in fact five records being returned with the recent_widgets method

I’ve gone as far as:

tests/unit/test_widget.rb

… fixtures :widgets

def test_find_recent_widgets w = widget.recent_widgets assert_not_nil w end

Any clues. Thanks!

If you want to assert that it has 5 exactly, use the asset_equal assertion on the array’s size.

def test_find_recent_widgets

assert_equal 5, widget.recent_widgets.size

end
