Overview

A test adapter that captures deliveries in memory without making real API calls. Use this in your test suite to assert on prompt content.

Setup (spec/support/action_prompt.rb)

RSpec.configure do |config|
config.before(:each) do
  ActionPrompt.reset_configuration!
  ActionPrompt::Adapters::Test.clear_deliveries!
end
end

Asserting on deliveries

it "sends the article body in the prompt" do
ArticleSummarizerPrompt.summarize(article).deliver_now

delivery = ActionPrompt::Adapters::Test.deliveries.last
expect(delivery[:prompt]).to include(article.body)
expect(delivery[:options][:model]).to eq("gpt-4o-mini")
end
