Struct EmbedderTestDouble 

pub struct EmbedderTestDouble { /* private fields */ }

Deterministic test double implementing TraverseEmbedderApi.

The double shares the production embedder’s event envelope, identifier scheme, compatible-capability lifecycle, and shutdown semantics through the same internal core; only capability execution is replaced with scripted results. It contains no business logic and never replaces runtime-owned behavior in production code paths.

Implementations

impl EmbedderTestDouble

pub fn new( workspace_id: impl Into<String>, app_id: impl Into<String>, app_version: impl Into<String>, platform: impl Into<String>, ) -> Self

Creates a double with the given identity, no scripted targets, and no compatible capabilities.

pub fn with_target_output( self, target_id: impl Into<String>, output: Value, ) -> Self

Scripts submit(target_id, _) to succeed with output.

pub fn with_target_error( self, target_id: impl Into<String>, code: impl Into<String>, message: impl Into<String>, ) -> Self

Scripts submit(target_id, _) to fail with a runtime-shaped error.

pub fn with_compatible_target( self, capability_id: impl Into<String>, platforms: Vec<String>, ) -> Self

Declares a compatible-mode capability with a platform allowlist.

Trait Implementations

impl TraverseEmbedderApi for EmbedderTestDouble

fn submit(&mut self, target_id: &str, input: &Value) -> SubmitOutcome

runtime.submit: execute a bundled workflow or WASM capability.

fn subscribe(&mut self, callback: EventCallback)

runtime.subscribe: register an ordered event callback. Previously emitted events are replayed to the new subscriber first, so late subscribers observe the identical ordered stream.

fn start_compatible( &mut self, capability_id: &str, input: &Value, ) -> CompatibleStartOutcome

compatible.start: start a compatible-mode capability instance.

fn stop_compatible( &mut self, capability_id: &str, instance_id: Option<&str>, ) -> CompatibleLifecycleOutcome

compatible.stop: gracefully stop one instance (instance_id) or every running instance of the capability (None).

fn kill_compatible( &mut self, capability_id: &str, instance_id: Option<&str>, ) -> CompatibleLifecycleOutcome

compatible.kill: force-terminate one instance (instance_id) or every running instance of the capability (None).

fn shutdown(&mut self) -> ShutdownOutcome

runtime.shutdown: kill running compatible instances and stop accepting operations. Idempotent.

fn release_evidence(&self) -> Value

Release evidence connecting this embedder to its package version, linked runtime, conformance version, and bundle digests (spec 068 FR-008, NFR-002).
