# mutare_oban v0.2.1 - Table of Contents > Mutare mutators for Oban ## Pages - [mutare_oban](readme.md) - [Changelog](changelog.md) - [LICENSE](license.md) ## Modules - [Mutare.Oban](Mutare.Oban.md): Mutation-testing mutators for [Oban](https://hexdocs.pm/oban) — a plugin for [Mutare](https://hexdocs.pm/mutare). - [Mutare.Oban.Enqueue](Mutare.Oban.Enqueue.md): Mutates the **enqueue options** of an Oban job — the keyword options passed when a job is built (`MyWorker.new(args, max_attempts: 3, unique: [...], schedule_in: 60)`). These options encode the job's retry / dedup / scheduling *policy*. Changing or removing an option tests whether the suite detects the corresponding change in behaviour. - [Mutare.Oban.WorkerReturn](Mutare.Oban.WorkerReturn.md): Swaps the **return value of an Oban worker callback** (`perform/1`, and Pro's `process/1`) for a *different but still valid* Oban outcome — the higher-signal analogue of `Mutare.Mutators.ReturnValue`'s sentinel.
