Mock gRPC API – Integration Testing

Here is how you might wanna mock a gRPC API, e.g. I mocked:

• A unary RPC, i.e. the SayHello API.
• A duplex stream (Bidirectional streaming RPC) which I called it Upload.

How to Start it

1. cd python/docs/integration-testing/mock-grpc-api.
2. make init.
3. make test.

Fixtures

I am auto loading all fixtures here to make adding new fixtures easier, but keeep in mind that your fixture file name should be like: *_fixture.py.

Fixture Loading and Execution Timing

Fixtures are NOT loaded at the beginning and cached forever. Fixtures in pytest have scope and lifecycle:

• function scope (default): Created/destroyed for each test function.
• class scope: Created once per test class.
• module scope: Created once per test file.
• session scope: Created once per entire test session.
