 #### Unit Tests
 
-Unit tests are crucial for ensuring the functionality of individual contracts and their components. These tests should
-be written using Hardhat and placed in the `/tests` directory. Each subdirectory should correspond to the version of the
-contract being tested, mirroring the structure of the `/contracts` directory.
+Every contract must be accompanied by high-quality unit tests.
+The [Moloch Testing Guide](https://github.com/MolochVentures/moloch/tree/master/test#readme) provides excellent recommendations,
+though some guidelines may not apply directly to this project.
 
-Follow the naming convention `*.test.ts` for unit test files, such as `myContract.test.ts`. This convention aids in the
-easy identification and organization of tests.
+> [!NOTE]
+> Tests should not only verify correct functionality but also be clear and well-structured for thorough peer
+> review—particularly for mission-critical Solidity code where tests are often as important as the implementation itself.
+
+- All new features or code changes must include comprehensive, relevant tests.
+- Refactoring should be performed separately from test modifications to maintain test integrity.
+- Tests must be reliable and deterministic; flaky tests will not be accepted.
+- The test suite runs automatically with every repository change, and all tests must pass before pull requests can be merged.
+- Maintain test coverage as close to 100% as possible, which will be verified during pull request reviews.
+
+Unit tests should be written using Hardhat and placed in the `/tests` directory.
+The subdirectory structure should mirror the `/contracts` directory, with each subdirectory corresponding to the
+Solidity version of the contracts being tested.
+
+Use the naming convention `*.test.ts` for unit test files (e.g., `myContract.test.ts`) to ensure consistent
+organization and easy identification of test files.
