Testing

(Other frameworks TBD.)

Testing in Rails

1. In Gemfile, add the capybara gem:

group :test do
  gem "capybara"
end

2. In test_helper.rb, add the following line somewhere above module ActiveSupport:

require "phlex/rails/testing"

3. Create test cases like tests/components/my_component_test.rb:

class Components::MyComponentTest < ActiveSupport::TestCase
  include Phlex::Testing::Capybara
  test "it should render a submit button" do
    render Components::MyComponent.new

    assert_selector "submit[name='hello_world']"
  end
end
