Este é um módulo Lua com o nome de Testes, não serve para utilizar em artigos na página principal, e deve ser usado de modo temporário pare que os outros usuários também o possam modificar e fazer testes rápidos de código. O módulo serve também para prevenir que o espaço nominal Módulo: encha de experimentos, visto que módulos Lua não podem existir como subpáginas no espaço nominal Usuário:, e não tem mensagens nem "maneira" de pedir a eliminação.

Se for necessário utilize um submódulo existente de ...módulo existente/Testes ou crie um submódulo experimental no seguinte formato para ajudar a manter as coisas arrumadas:
