## Summary Some factories are failing with `PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_ci_namespace_mirrors_on_namespace_id"`. The workaround is to retry factory creation. ### Steps to reproduce 1. Enter Rails console `gdk rails console` 2. Create `FactoryBot.create(:board_group_recent_visit)` ```ruby FactoryBot.create(:board_group_recent_visit) # factory is created => #<BoardGroupRecentVisit:0x000000028223f508 id: 1, created_at: Wed, 28 Feb 2024 17:25:45.371008000 UTC +00:00, updated_at: Wed, 28 Feb 2024 17:25:45.371008000 UTC +00:00, user_id: 70, board_id: 1, group_id: 96> ``` 3. Create the same factory once more ```ruby FactoryBot.create(:board_group_recent_visit) # on second try failed with the same `index_ci_namespace_mirrors_on_namespace_id` ActiveRecord::RecordNotUnique: PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_ci_namespace_mirrors_on_namespace_id" DETAIL: Key (namespace_id)=(100) already exists. ``` 4. Repeat factor creation ```ruby FactoryBot.create(:board_group_recent_visit) # didn't fail on third time => #<BoardGroupRecentVisit:0x0000000128e7ec48 id: 2, created_at: Wed, 28 Feb 2024 17:26:11.482766000 UTC +00:00, updated_at: Wed, 28 Feb 2024 17:26:11.482766000 UTC +00:00, user_id: 73, board_id: 2, group_id: 102> ``` Other example failures can be seen in https://gitlab.com/gitlab-org/quality/pg-dump-generator/-/jobs/6393739616 by searching `PG::UniqueViolation`
