O `TestClient` faz algumas mágicas para invocar a aplicação FastAPI assíncrona em suas funções `def` normais, utilizando o pytest padrão. Porém a mágica não acontece mais quando nós estamos utilizando dentro de funções assíncronas. Ao executar os nossos testes de forma assíncrona, nós não podemos mais utilizar o `TestClient` dentro das nossas funções de teste.
