Case details

Testing requires realistic and diverse datasets to validate application behavior effectively. Manually creating or maintaining such datasets can become repetitive and error-prone. Tools like Datafaker and Instancio simplify and enhance this process, offering reliable and scalable solutions to generate random values for tests.

Software Architecture

Andres Sacco has been working as a developer since 2007 in different languages, including Java, PHP, NodeJs, Scala, and Kotlin. Most of his background is in Java and the libraries or frameworks associated with this language. In most of the companies he worked for, he researched new technologies to improve the performance, stability, and quality of the applications of each company.

In 2017 he started to find new ways to optimize the transference of data between applications to reduce the cost of infrastructure. He suggested some actions, some of them applicable in all the manual microservices and others in just a few. All this work concludes with the creation of a series of theoric-practical projects, which are available on the page Manning.com Recently he published a book on Apress about the last version of Scala. Also, he published a set of theoric-practical projects about uncommon ways of testing like architecture tests and chaos engineering.

He dictated internal courses to different audiences like developers, business analysts, and commercial people. Also, he participates as a Technical Reviewer on the books of the editorials: Manning, Apress, and Packt.
