The project focused on providing support for the testing process of the tool. This involved performing manual tests on new functionalities and conducting acceptance tests for bug fixes from internal developers and the community.

In addition, automated test cases were carried out using a custom framework based on TestNG.

Regression tests were executed on new versions, and user reports from the Community or Open Source version were submitted to the Github repository, where support is provided to users and solutions to bugs and common issues are discussed.
