Summary for 2025-01 (sloalchemist/potions): Delivered targeted unit tests and ownership/authorization validations for potion stands to harden multi-tenant interactions and protect in-game economy. Strengthened ownership-based controls across core actions (ownership checks for retrievals, price modifications, and gold collection) with stable test outcomes and clearer failure signals. Key features delivered: - Expanded Potion Stand Ownership and Interaction Tests: coverage for retrieval, adding items, and cross-community access control, increasing confidence in multi-tenant behavior. - Ownership Restrictions for Potion Stand Price Modifications: tests ensuring only owners can raise or lower prices, validating price operations across communities. - Gold Collection Ownership Validation for Potion Stands: tests verifying only authorized community members can collect gold and that transfers are correct. Major bugs fixed (or regressions resolved): - Stabilized ownership and access control logic in unit tests, addressing intermittent failures in retrieval and price/collection flows. - Addressed test brittleness by aligning community ownership assumptions and updated test data for initialized gold collection. Overall impact and accomplishments: - Significant reduction in risk around unauthorized actions (price changes, gold collection) and cross-community interactions. - Improved test suite reliability, enabling faster deployment cycles and safer feature rollouts for the potion stand economy. Technologies/skills demonstrated: - Unit testing and test coverage expansion, ownership/authorization validation, cross-community access control, and test debugging/debug iteration with Git history.
