-// Usage: generally, non-unit-test code shouldn't depend on unit test code.
-// However, we have some code like models.CheckConsistencyFor, which need to do some unit test works.
-// Now we can not decouple models.CheckConsistencyFor from unit test code easily (cycle-import reasons).
-// So we introduce this `unit test bridge`:
-// * When a release binary is built, no testing/assert framework would be compiled into the binary, and CheckConsistencyFor won't run unit test related code
-// * When a unit test binary is built, the unit test code will init this bridge, then CheckConsistencyFor can run unit test related code
-//
-// Tester/Assert are intermediate interfaces, they should NOT be used in new code.
-// One day, if CheckConsistencyFor is clean enough, we can remove these intermediate interfaces.
