Simulating the good, the bad, the ugly and gRPC with WireMock

WireMock is tool for mocking HTTP-based protocols. Although it supports a wide range of languages via its JSON API and client libraries, it's built on Java so has unparalleled integration options and flexibility on the JVM.
Recently it gained support for mocking gRPC and this includes an extension of the Java DSL specifically for this use case.
In this talk I'll briefly discuss the motivations for mocking APIs and introduce WireMock's core capabilities, then show how it can be used to elegantly simulate gRPC APIs (including those that haven't been implemented yet). I'll also dive into another advanced use case - simulating faults and failures in order to facilitate resilience testing of your client code.
