Unified test foundation providing multiple isolation modes for OTP testing.

This module provides macros and utilities to establish different levels of test isolation, enabling async testing while preventing process conflicts and ensuring proper cleanup.

Isolation Modes

• :basic - Basic isolation with unique naming
• :registry - Registry-based process isolation
• :full_isolation - Complete process and ETS isolation
• :contamination_detection - Isolation with contamination detection

Usage

defmodule MyApp.MyModuleTest do
  use ExUnit.Case
  use Supertester.UnifiedTestFoundation, isolation: :full_isolation

  test "my test", context do
    # Test runs with full isolation
  end
end
