"""Tests for the Edictum Contract Cookbook (examples/contract_cookbook.py).

Covers all 4 parts:
  Part 1: Preconditions (10 contracts)
  Part 2: Postconditions (5 contracts)
  Part 3: Session contracts (6 factories)
  Part 4: Compositions (3 functions)

Every contract has at least one pass test and one fail test.
