Sandbox adapter for isolated testing of applications using ElixirCache.

This module provides a mock implementation of all cache adapters, allowing tests to run in isolation without interfering with each other's data. The sandbox uses a basic Agent to store data in memory and implements the full range of caching operations supported by all adapters.

Features

• Isolated cache namespaces for concurrent testing
• Support for all standard cache operations
• Implementation of Redis-specific features like hash and JSON operations
• Implementation of ETS-specific operations for complete testing compatibility
• Lightweight in-memory storage for fast test execution

Usage

The Sandbox adapter is typically enabled through the sandbox? option when defining a cache module:

defmodule MyApp.TestCache do
  use Cache,
    adapter: Cache.Redis,  # Original adapter doesn't matter when sandbox is enabled
    name: :test_cache,
    opts: [],
    sandbox?: Mix.env() == :test
end

In your tests, use Cache.SandboxRegistry.start(MyApp.TestCache) in the setup block to ensure proper isolation between test cases.

Note: This adapter should not be used in production environments.
