Controller Spec
Important: These docs are for the outdated Jets 5 versions and below. For the latest Jets docs: docs.rubyonjets.com
Here’s a simple example of a controller spec.
spec/controllers/post_controller_spec.rb:
describe PostsController, type: :controller do
it "index returns a success response" do
get '/posts'
expect(response.status).to eq 200
end
end
The controller spec helpers provide the http verb methods: get, post, put, patch, delete. You can pass headers, params, query, and body to the the methods also. Example:
describe PostsController, type: :controller do
it "index returns a success response" do
get '/posts', headers: {"MyHeader": "foo"}
expect(response.status).to eq 200
end
end
You can override what is passed as a body by using the body param along with Content-Type header. This works for non-GET requests only.
describe PostsController, type: :controller do
it "index returns a success response" do
article = JSON.generate(title: "Hello", content: "World!")
post '/posts', body: article, headers: {"Content-Type": "application/json"}
expect(response.status).to eq 201
end
end
The response will have the status, headers, and body set after an test http request has been called. Example:
describe PostsController, type: :controller do
it "index returns a success response" do
get '/posts'
expect(response.status).to eq 200
pp response.headers
pp response.body
end
end
When you run specs, you may need to migrate first. Here are the commands:
JETS_ENV=test jets db:create db:migrate
bundle exec rspec
