What are some examples of testing in Rails?

In Rails, you can use RSpec for unit tests, Capybara for integration tests, and FactoryBot for setting up test data.

Can you give me a simple RSpec test example?

Sure! Here's a basic example:

RSpec.describe User, type: :model do
  it 'is valid with valid attributes' do
    user = User.new(name: 'John', email: '[email protected]')
    expect(user).to be_valid
  end
end

What about testing controllers?

For controller testing, you can use the following example:

RSpec.describe UsersController, type: :controller do
  describe 'GET #index' do
    it 'returns a success response' do
      get :index
      expect(response).to be_successful
    end
  end
end

How do I test views in Rails?

You can test views using RSpec and Capybara. For example:

RSpec.describe 'users/index.html.erb', type: :view do
  it 'displays the user name' do
    assign(:users, [User.new(name: 'John')])
    render
    expect(rendered).to include('John')
  end
end
