| // Package ormmocks contains generated mocks for orm types that can be used | ||

| // as this useful way for unit testing using an in-memory database. Rather | ||
| // than attempting to mock a whole table or database instance, instead | ||
| // a mock Hook instance can be passed in to verify that the expected | ||
| // insert/update/delete operations are happening in the database. | ||
| // | ||
| // The Eq function gomock.Matcher that compares protobuf messages can | ||
| // be used in gomock EXPECT functions. | ||

| // See TestHooks in ormdb/module_test.go for examples of how to use | ||
| // mock Hooks in a real-world scenario. | ||
