Visão Geral
Este Curso Python Unit Testing and Test-Driven Development, oferece uma imersão nos conceitos de testes unitários utilizando Python, com foco no Desenvolvimento Orientado a Testes (TDD). Os alunos aprenderão a escrever testes automatizados para garantir a qualidade do código, além de implementar a metodologia TDD para desenvolver aplicações de forma mais eficiente e confiável. O curso cobre bibliotecas populares de testes em Python, como unittest
e pytest
, e ensina a aplicar boas práticas de teste em projetos reais.
