A new configuration setup now allows specifying a path for database properties via command-line arguments during application startup. This update also changes the call signature for `DatabaseConnection.initialize()` method to accept a path argument. Similarly, methods in `PropertiesLoader`, `PropertiesWriter`, and `MailSettings` classes were also updated to use the specified path when working with properties files. The `TestForm` class's tests were updated accordingly to handle these changes.
The changes add a new TestForm class to implement unit tests for form handling in the application. The included tests verify the storing, retrieving, and verification of forms from a database, as well as form object creation and confirmation of form data. This is a step towards improving the code's reliability and making it easier to catch potential bugs or issues.
