Syntest-JavaScript: Automated Unit-Level Test Case Generation for JavaScript

Over the last decades, various tools (e.g., AUSTIN and EvoSuite) have been developed to automate the process of unit-level test case generation. Most of these tools are designed for statically-typed languages, such as C and Java. However, as is shown in recent Stack Overflow developer surveys, the popularity of dynamically-typed languages, such as JavaScript and Python, has been increasing and is dominating the charts. Only recently, tools for automated test case generation of dynamically-typed languages have started to emerge (e.g., Pynguin for Python). However, to the best of our knowledge, there is no tool that focuses on automated test case generation for server-side JavaScript. To this aim, we introduce SynTest-JavaScript, a user-friendly tool for automated unit-level test case generation for (server-side) JavaScript. To showcase the effectiveness of SynTest-JavaScript, we empirically evaluate it on five large open-source JavaScript projects and one artificial one.
