Have you encountered difficulties when testing this project?

When checking a Java project, difficulties often arise related to:

• Understanding the architecture and relationships between classes, especially if the project is large and poorly documented.
• Lack or insufficiency of tests, which complicates verifying correctness.
• Using outdated or non-standard libraries that are difficult to configure or update.
• Problems with build configuration (e.g., Maven or Gradle), which can cause the project not to compile or run incorrectly.

For effective verification, it is important to have access to documentation, tests, the development environment, and time to study the code.
