PROFILE
Xavier Garabito
During a two-month period, Garabito modernized the testing framework and enhanced dependency injection correctness in the google/dagger repository. In April, Garabito migrated legacy Java tests to use JUnit’s assertThrows, replacing outdated try/catch/fail and ExpectedException patterns to improve test readability, reliability, and maintainability. The changes removed deprecated suppressions and enabled safer future refactoring. In May, Garabito implemented strict duplicate detection for Dagger Map Bindings, introducing a compile-time verification option that prevents duplicate key masking across component hierarchies. This work, leveraging Java and test-driven development, improved the stability and maintainability of Dagger’s codebase without introducing new bugs.

May 1, 2026May 2026: Implemented cross-hierarchy strict duplicate detection for Dagger Map Bindings, adding a compile-time verification across the full binding graph. Introduced a new compiler option to enable this behavior and updated release notes to reflect the fix for duplicate masking in Map components. These changes improve DI correctness, prevent runtime failures with Guava-backed maps, and reduce maintenance cost.
