Test Behavior, Not Choreography
Part 5 of Getting Started with Mocks: a test that pinned the retry schedule broke on a change no customer could notice. Here is how to rewrite it.
gRPC Mocks, Tests and Contract Checks From a .proto
Turn a .proto file into gRPC mocks and tests with proxymock, record real responses, and catch field type changes that protobuf decoding silently accepts.

They Aren't All Mocks
Part 6 of Getting Started with Mocks: stub, spy, fake, mock, and dummy, sorted by what each one does. Java, Node, Go, Python.
What Mocks Are Actually For
