// ConsoleCommand is tested primarily with tests in the "repl" package.
// It is not tested here because the Console uses a readline-like library
// that takes over stdin/stdout. It is difficult to test directly. The
// core logic is tested in "repl"
//
// This file still contains some tests using the stdin-based input.
