# forge.testing.assert_entry_at

```python
forge.testing.assert_entry_at(run: TestRun, bar: int, *, side: str | None = None) -> None
```

An entry was filled on primary bar ``bar``, on the ``side`` given when there is one.

A negative ``bar`` counts from the end. The failure lists the entries on either side of ``bar``.
