Worked on the ydb-platform/nbs repository to improve code quality and maintainability in Go-based test suites. Addressed a linter warning in filesystem_snapshots_test.go by removing an unused struct initialization and replacing it with a direct variable assignment, which streamlined the test logic and reduced unnecessary code. This change helped minimize CI lint noise and made code reviews more efficient by clarifying test intent. Focused on Go and testing best practices, the update enhanced the reliability and readability of the test code. The work contributed to a cleaner development workflow and supported ongoing efforts to maintain high standards in automated testing.
