## Async vs Sync *path operations*

Use `async` *path operations* only when fully certain that the logic called inside is compatible with async and await (it's called with `await`) or that doesn't block.

```python
from fastapi import FastAPI

app = FastAPI()


# Use async def when calling async code
@app.get("/async-items/")
async def read_async_items():

	},
}

func TestReplicationResync(t *testing.T) {
	ctx := t.Context()
	for i, test := range replicationConfigTests {
		if sync := test.rcfg.Resync(ctx, test.info, test.dsc, test.tgtStatuses); sync.mustResync() != test.expectedSync {
			t.Errorf("Test%d (%s): Resync  got %t , want %t", i+1, test.name, sync.mustResync(), test.expectedSync)
		}
	}
