Worked on the GreenCityMVP21 repository to enhance the reliability and maintainability of image upload validation. Focused on backend development using Java, JUnit, and Mockito, the developer introduced a comprehensive suite of unit tests for the ImageValidator, covering null inputs, allowed and disallowed MIME types, and edge cases. The test suite was further refactored to use parameterized tests, improving efficiency and maintainability. These changes strengthened data integrity by ensuring only valid image types are accepted and improved error handling, reducing the risk of invalid uploads reaching production. The work emphasized test-driven development and robust validation practices throughout the project.
