ExUnit helpers for asserting on LangchainPrompt.Adapters.Test calls.

Import this in your test files:

import LangchainPrompt.TestAssertions

Macros

• assert_adapter_called/0 — asserts the adapter was called (ignores payload).
• assert_adapter_called/1 — asserts the adapter was called and runs an assertion function on the payload.
• refute_adapter_called/0 — asserts the adapter was NOT called.

Example

test "sends the right system prompt" do
  LangchainPrompt.execute(MyPrompt, assigns)

  assert_adapter_called(fn payload ->
    system_msg = hd(payload.messages)
    assert system_msg.role == :system
    assert system_msg.content =~ "summarise"
  end)
end
