# Override Kullanarak Dependency'leri Test Etme { #testing-dependencies-with-overrides }

## Test Sırasında Dependency Override Etme { #overriding-dependencies-during-testing }

Test yazarken bazı durumlarda bir dependency'yi override etmek isteyebilirsiniz.

Orijinal dependency'nin (ve varsa tüm alt dependency'lerinin) çalışmasını istemezsiniz.

FastAPI will still be able to override it.

Then you can reset your overrides (remove them) by setting `app.dependency_overrides` to be an empty `dict`:

```Python
app.dependency_overrides = {}
