Console::Test -- a tiny in-engine test harness.

Tests run inside the real DragonRuby runtime, so they exercise the actual renderer, the actual output collections and the actual mruby build rather than a stand-in. Failures are collected, printed, and summarised in a single machine-readable line the runner script can grep.

class MySuite
  include Console::Test

  def setup
    @thing = []
  end

  test 'does the thing' do
    assert_equal 2, @thing.size
  end
end

Each test block is evaluated against a fresh instance of the suite, so setup runs first and instance state does not leak between tests.

def test(name, &block): Declare a test. Runs against a fresh instance of this suite.
