The Proxy-Wasm ABI and associated SDKs enable developers to build extensions in any of the supported languages and deliver the plugins as WebAssembly modules at run-time. This repository contains a standalone runner which serves as a test harness and simulator for Proxy-Wasm extensions, enabling quick testing in a controlled environment.

The basic usage of this test-framework is provided in the examples/ folder which contains mocking of proxy-wasm modules provided in the proxy-wasm-rust-sdk examples/.

• Low-level expectation setting over most host-side functions that are consumed immediately
• Checking of residual low-level expectations after wasm-function call has completed
• Various high-level (simulator defaults) expectations that persist across several host-function calls as opposed to being immediately consumed
• Expectation setting over returns from functions exposed on the proxy-wasm module

• Complete default implementation for all host-side functions
• Low-level expectation setting for the remaining host-side functions
• High-level expectation setting for the remaining host-side functions
• Integration test examples
