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.
|
|
