É impossível testar absolutamente tudo na tua base de código. O melhor que podes fazer é ser inteligente na forma como te diriges a casos de utilização específicos. Procura casos limite, caminhos através do código e quaisquer outros atributos interessantes do código. A tua principal esperança é que não tenhas deixado nenhum grande buraco na tua rede de segurança. No entanto, podes fazer melhor do que esperar. Podes preencher essas lacunas com testes baseados em propriedades.
Neste capítulo, vais aprender como fazer testes baseados em propriedades com uma biblioteca Python chamada Hypothesis. Usarás Hypothesis para gerar casos de teste para ti, muitas vezes de maneiras que nunca poderias esperar. Aprenderás como rastrear casos de teste que falharam, criar dados de entrada de novas maneiras e até mesmo fazer com que Hypothesis crie combinações de algoritmos para testar o teu software. Hypothesis protegerá a tua base de código contra toda uma nova combinação de erros.
