 #### Unit Tests
 - Ensure unit tests are written to achieve at least 80% coverage.
 - Use `stretchr/testify` for tests and follow the test suite pattern.
-- `mockery` is used to generate mocks; configurations are in `/backend/.mockery.yml`.
+- `mockery` is used to generate mocks; configurations for private and public interfaces are in `.mockery.private.yml` and `.mockery.public.yml` respectively. Mocks can be generated using `make mockery` command from the project root directory.
 - Place generated mocks in the `/backend/tests/mocks/` directory.
 - Unit tests can be run using `make test_unit` command from the project root directory. Alternatively `go test` command can also be used from the `/backend` directory with applicable flags.
