How can I test decorators in a Rails application?
To test decorators in Rails, you can use RSpec along with a testing framework like FactoryBot to create instances of your models.
Can you provide an example of a test case for a decorator?
Sure! Here's a simple example:
RSpec.describe UserDecorator do
let(:user) { FactoryBot.create(:user) }
let(:decorated_user) { user.decorate }
it 'returns the full name' do
expect(decorated_user.full_name).to eq('John Doe')
end
end
What if I want to test multiple methods in the decorator?
You can add more it
blocks within the same RSpec.describe
block to test each method individually. Just ensure each test is focused on one aspect.
Are there any best practices for testing decorators?
Yes! Keep your tests isolated, use descriptive names for your test cases, and avoid testing the underlying model's behavior in decorator tests.
