HTTP module for stripity_stripe that enables PaperTiger sandbox isolation.

When using stripity_stripe with PaperTiger, this module ensures that all HTTP requests include the namespace header needed for test isolation.

Configuration

In your config/test.exs:

config :stripity_stripe,
  http_module: PaperTiger.StripityStripeHackney

How It Works

1. Test calls PaperTiger.Test.checkout_paper_tiger(%{}) which sets up namespace
2. This module reads the namespace and adds it as an HTTP header
3. PaperTiger's Sandbox plug reads the header and scopes all operations
4. Test data is isolated between tests

Child Process Support

For tests that spawn child processes (like Phoenix LiveView tests), the namespace is automatically shared via Application env. When you call checkout_paper_tiger/1, it sets both the process dictionary (for the test process) and Application env (for child processes like LiveView).

This means LiveView tests "just work" - no extra configuration needed.

Example

defmodule MyApp.BillingTest do
  use MyApp.ConnCase, async: true

  import PaperTiger.Test

  setup do
    :ok = checkout_paper_tiger(%{})
    # ... rest of setup
  end

  test "creates subscription", %{conn: conn} do
    # Stripe calls from this test AND from LiveView are isolated
    {:ok, _sub} = Stripe.Subscription.create(%{...})

    {:ok, live, _html} = live(conn, "/billing")
    # LiveView's Stripe calls use the same sandbox!
  end
end
