Abstract:

Integration and functional testing of systems is quite important for ensuring reliability and correctness. However end-to-end testing is susceptible to randomness due to interactions with external services, which may behave non-deterministically. This presents a need to create hermetic test environments, so that systems can be tested in a vacuum, i.e., without interacting with external dependencies. This normally requires setting up fakes and mocks to stub responses from interactions with external dependencies. However, stubs and mocks need to be manually created and maintained which adds toil. RPC Replay is a simple solution to this problem. RPC Replay automates the task of creating stubbed responses. The grpcreplay package in Golang provides support for RPC Replay of gRPC calls. In this paper, we study RPC Replay, its benefits, caveats and usage in Golang applications.
