🌐 Integrate VCR and WebMock for Deterministic External Tests​

Combine VCR cassettes with WebMock request expectations to assert HTTP interactions precisely. Use custom request matchers and cassette hooks for parameterized URIs and dynamic headers.

# spec_helper.rb
VCR.configure do |c|
  c.hook_into :webmock
  c.configure_rspec_metadata!
  c.default_cassette_options = { match_requests_on: [:method, :uri, lambda { |r1, r2| r1.headers['X-Auth-Token'] == r2.headers['X-Auth-Token'] }] }
end

RSpec.describe ExternalClient, :vcr do
  it 'fetches user data', :vcr do
    expect(WebMock).to have_requested(:get, /users\/\d+/).with(headers: { 'X-Auth-Token' => 'abc123' })
    ExternalClient.fetch_user(42)
  end
end
