package unittestbridge
// 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.
// Tester is the same as TestingT in "stretchr/testify/assert"
// Tester can be used in non-unit-test code (ex: models.CheckConsistencyFor), it is used to isolate dependencies
