Worked on the software-mansion/scarb repository to enhance the reliability of the Scarab-Execute Extension’s test suite. Focused on refactoring a test to ensure a panic was executed only within a specific conditional block, which improved determinism and reduced flakiness in continuous integration runs. Emphasized quality assurance and stability over feature development, addressing a critical bug that previously caused unreliable test outcomes. Utilized Rust for both implementation and testing, applying test-driven debugging and CI reliability techniques. The work contributed to a more stable release process by lowering the risk of intermittent test failures and strengthening the overall test environment for the project.
