Redis Configuration Validator

Build a utility module that validates Redis server configurations before test execution, ensuring that common misconfigurations are detected early with clear error messages.

Capabilities

Validate Redis Executable Path

• When given a valid Redis executable path, the validator confirms it exists and is executable @test
• When given an invalid or non-existent Redis executable path, the validator raises an appropriate configuration error @test

Validate Unix Socket Path Length

• When given a Unix socket path within acceptable length limits, the validator accepts it @test
• When given a Unix socket path that exceeds platform-specific length limits, the validator raises an appropriate socket path error @test

Validate Redis Version Compatibility

• When given a Redis server executable version 2.6 or higher, the validator accepts it @test
• When given a Redis server executable version lower than 2.6, the validator raises an appropriate version compatibility error @test

    """
    Validates that the Redis executable exists and is accessible.

    Args:

    """
    pass

def validate_socket_path(socket_path: str) -> None:
    """
    Validates that a Unix socket path is within acceptable length limits.
    Platform-specific limits apply (Linux: 107 chars, others: 104 chars).

    Args:
        socket_path: Path for the Unix socket

    Raises:
        Exception if the socket path is too long for the platform
    """
    pass

def validate_redis_version(executable_path: str, min_version: str = "2.6") -> None:
    """
    Validates that the Redis server version meets minimum requirements.

    Args:
        executable_path: Path to the Redis server executable
        min_version: Minimum acceptable version (default: "2.6")

    Raises:
        Exception if the Redis version is unsupported
