The Python SDK has a testing harness to test your Restate handlers. This uses Testcontainers to run a Restate Server in a Docker container and provides a client to let you test your Restate handlers.

​
Setup

Install the package: 
pip install restate_sdk[harness]

​
Testing handlers

If you have a service as follows: 
import restate

greeter = restate.Service("greeter")


@greeter.handler()
async def greet(ctx: restate.Context, name: str) -> str:
    return f"Hello {name}!"


app = restate.app(services=[greeter])
Then you can test it via: 
import restate

with restate.test_harness(app) as harness:
    restate_client = harness.ingress_client()
    print(restate_client.post("/greeter/greet", json="Alice").json())
