What does network-runner do? The primary focus of network-runner is to create a local network, as a test framework for local development.
Why network-runner as a binary? Previously, each team was still required to write a substantial amount of Go code to integrate with network-runner. And the circular dependency on avalanchego made it unusable within avalanchego itself. Using network-runner as a binary (rather than Go package) eliminates the complexity of such dependency management.
Why network-runner needs RPC server? network-runner needs to provide more complex workflow such as replace, restart, inject fail points, etc.. The RPC server will expose basic node operations to enable a separation of concerns such that one team develops test framework, and the other writes test cases and its controlling logic.
Why gRPC? The RPC server leads to more modular test components, and gRPC enables greater flexibility. The protocol buffer increases flexibility as we develop more complicated test cases. And gRPC opens up a variety of different approaches for how to write test controller (e.g., Rust). See rpcpb/rpc.proto for service definition.
Why gRPC gateway? gRPC gateway exposes gRPC API via HTTP, without us writing any code. Which can be useful if a test controller writer does not want to deal with gRPC.
