7.3: Write Integration Tests

[justin808]

Overview

Create comprehensive integration test suite.

Parent Epic: #70
Priority: P1

Prerequisites

• All controllers and components completed
• 6.1: Implement Streaming for Story List #96 (6.1: Implement Streaming for Story List)
• 6.2: Implement Streaming for Comments #97 (6.2: Implement Streaming for Comments)

Next Issues (after this is complete)

• 7.4: Add Production Configuration (ensure tests pass in CI)

Acceptance Criteria

• System tests for story list page (all types: top, new, show, ask, jobs)
• System tests for pagination
• System tests for story detail page
• System tests for comment display
• System tests for user profile page
• System tests for error states (404, etc.)
• Tests verify RSC streaming works
• All tests passing locally
• CI configuration for running tests

Implementation Notes

Use Capybara with a JavaScript driver for full RSC testing:

# spec/system/stories_spec.rb
require 'rails_helper'

RSpec.describe 'Stories', type: :system do
  it 'displays top stories' do
    visit '/news/1'
    expect(page).to have_css('.story', minimum: 1)
  end
  
  it 'paginates correctly' do
    visit '/news/1'
    click_link 'More'
    expect(page).to have_current_path('/news/2')
  end
end

Consider mocking the HN API for reliable, fast tests.
