Test your JSON strings.
cd path/to/your/rails-project
./script/plugin install git://github.com/alto/assert_json.git
Or if you prefer bundler
# in your Gemfile
gem 'assert_json'
class MyActionTest < ActionController::TestCase
include AssertJson
def test_my_action
get :my_action, :format => 'json'
# => @response.body= '{"key":[{"inner_key1":"value1"},{"inner_key2":"value2"}, {'special-key': null}]}'
assert_json(@response.body) do
has :key do
has :inner_key1, 'value1'
has :inner_key2, /lue2/
end
has 'special-key', nil
has_not :key_not_included
end
end
end
Arrays are little bit special. If you want to test single items (or skip others) you
use item(i)
to select the item to test, like this
assert_json '[{"id":1, "key":"test", "name":"test"}, {"id":2, "key":"test", "name":"test"}, {"id":3, "key":"test", "name":"test"}]' do
item 0 do
has :id, 1
has :key, 'test'
has :name, 'test'
end
item 2 do
has 'id', 3
end
end
You can also check the size of arrays like this
assert_json '["value1", "value2"]' do
has_length_of 2
end
To test that objects have the declared set of properties and nothing more,
include has_only
at any level, like this
assert_json '[{"id":1, "key":"test", "name":"test"}, {"id":2, "key":"test", "name":"test"}, {"id":3, "key":"test", "name":"test"}]' do
has_only
item 0 do
has :id, 1
has :key, 'test'
has :name, 'test'
end
item 1 do
has 'id', 2
has 'key', 'test'
end
end
# Failure: element 1 has unexpected keys: name
