Artigo Científico Acesso aberto Uma linguagem de domínio específico externa para implementação de testes de unidade e de integração em softwares orientados a objetos(2017) Santini, Rafael de Melo LimaTestes de unidade e de integração implementados na própria linguagem utilizada no desenvolvimento do software podem resultar em códigos pouco legíveis e mais verbosos. Nesse contexto, este artigo descreve o modelo de uma linguagem de domínio específico externa e faz a comparação entre testes implementados na linguagem Java com os equivalentes à linguagem proposta. A pesquisa conclui que os testes implementados na nova linguagem são menos verbosos por apresentarem uma quantidade de símbolos e linhas menor em relação aos testes escritos em Java e são mais legíveis ao incorporar as funcionalidades do framework JUnit e da biblioteca Mockito.Artigo Científico Acesso embargado Análise dos Tweets sobre a Universidade do Sul de Santa Catarina – Unisul, por meio da mineração de texto e análise de sentimentos(2017) Scandolara, Mariana da Rosa; Carlos, Arthur WeberAcknowledging the competition among higher education institutions, the universities are in search of innovating strategies for their activities.
