Teasy framework: uma solução para testes automatizados em aplicações web

Abstract

Functional testing is the most used solution within the development cycle to detect bugs in systems. Among the existing approaches to conducting tests, automation can reduce effort in the medium and long term, this is due to the possibility of re-running the test without the aid of a tester. Based on this, the adoption of automation can reduce the time and costs related to regression testing within a development process, in addition to increasing the reliability and quality of software. However, when development delays or problems occur during a previous step, the time for creating the tests is impacted, causing automation with problems or even the manual verification of functionalities. From this, domain specific tools and languages were developed in order to insert the tests in other stages, such as, for example, the analysis stage, which allows automation before or during development. In spite of this, the agile scenario and constant changing requirements have an impact on this practice, in addition to the difficulty of maintaining and storing automated tests, considering that in the next version of the system an old test may become obsolete due to changes in requirements. Based on this, it was investigated within the literature through systematic mapping and snowballing all domain specific languages for functional tests, in order to collect the benefits, limitations and trends of each language. After analyzing the results, the Teasy proposal was defined, a framework for functional tests with a focus on creating a specific domain language based on the benefits, trends and reduction of the problems reported in the studies. The Teasy Framework is composed of a scalable test structure (Teasy Structure), a sequence generator (Teasy Generator) and a domain specific language for testing applications web (Teasy Language). Teasy Language aims to provide maximum reuse, automatic test generation and ease of use. Due to comparisons made between the types of languages, Teasy Language was defined as design, which increases its productivity and reduces the time required for the specification of the system to be tested. In order to evaluate the framework, a quasi-experiment and usability evaluation with specialists were carried out. Thus, it was possible to compare the representativeness, effectiveness and usability of the framework.
