Do we need this class-level declaration still? Class vars always confuse me, but this means somebody can do:
TestClient.async_backend["backend"] = "trio"to default all future TestClient instances to use the Trio backend, right?
I know removing this would be slightly changing the API, however in the code examples we gave we only modified instance attributes and that usage should stay the same. What's your thinking around this?

As implemented in #1157,
TestClient.async_backendwas a class-level attribute. This made it easy to monkeypatch for use in starlette tests, but makes it difficult/impossible to run different test client backends concurrently (in threads).This PR changes TestClient to accept a
backendandbackend_optionsarguments which allow a user to specify the backend options for only that TestClient instance. The class attribute will remain as the default for these arguments.Fixes #1209
