• assert creating a conflicting record with clause.OnConflict{DoNothing: true} completes without error, reports 0 rows affected, and preserves all existing database columns unchanged
• assert creating a conflicting record with clause.OnConflict{UpdateAll: true} overwrites all mutable non-primary columns and reports 1 row affected
• assert clause.OnConflict with specific Columns and AssignmentColumns updates only designated fields while leaving other non-conflicting columns at their pre-existing values
• assert clause.OnConflict with Assignments and gorm.Expr evaluates SQL expressions such as counter increments directly during upsert
• assert batch Create with clause.OnConflict applies upsert updates to conflicting rows while inserting non-conflicting rows in the same transaction
