# `Portals.Fixtures.CallbackTarget`
[🔗](https://github.com/Ziinc/portals/blob/v0.1.0/lib/portals/conformance/callback_target.ex#L1)

The BEAM-side callback target the shared conformance suites call back
into (as `Elixir.Portals.Fixtures.CallbackTarget`) from every SDK's
`bench_worker` fixture.

Callback targets must already exist as atoms before a worker can name
them, so `Portals.Conformance.WorkerSuite` users load this module in
their `test_helper.exs` with `Code.ensure_loaded!/1`.

# `boom`
