ports.RunSession interfaces. +// +// # Overview +// +// facadetest is the third member of the AWF testutil family alongside +// internal/testutil/mocks (thread-safe port mocks) and +// internal/testutil/builders (fluent object builders). Its purpose is +// different: instead of recording or stubbing individual method calls, it +// lets a test script a complete event sequence that a FakeSession will emit in +// order, including synchronization points where the session pauses until the +// consumer calls Respond. +// +// # Architecture +// +// The Fake struct implements ports.WorkflowFacade. +// FakeSession implements ports.RunSession. +// +// Design decisions: +// - D37: New testutil sub-packages get doc.go per CLAUDE.md convention. +// - D38: Builder-style API allows all consumer packages (CLI, API, ACP, conformance +// suite) to share one fake rather than defining per-package inline doubles. +// +// The package depends only on: +// - internal/domain/ports — the interface contract Fake and FakeSession satisfy. +// - internal/application — MapError for ErrorCode mapping in WithTerminalFailed. +// +// It does NOT depend on the production FacadeAdapter (internal/interfaces/facade). +// Depending on the adapter would create a compilation cycle and block the +// parallel build of T064 and T058. +// +// # Event Channel Lifecycle +// +// Each call to Fake.Run creates a fresh FakeSession with its own buffered event +// channel, sized to len(script)+1 to avoid blocking the pump goroutine. The +// pump goroutine sends events in order and exits (closing the channel) after: +// - a terminal event (EventWorkflowCompleted or EventWorkflowFailed) is sent, or +// - the context is cancelled, or +// - FakeSession.Close is called. +// +// The events channel is always closed before Close returns, so reading from +// sess.Events() after sess.Close() immediately yields the zero value and false. +// +// # Builder API +// +// Construct a Fake with the New() constructor and chain builder methods: +// +// f := facadetest.New(). +// Script( +// ports.Event{Kind: ports.EventRunStarted, Seq: 1}, +// ports.Event{Kind: ports.EventStepStarted, Seq: 2}, +// ). +// WithTerminalCompleted() +// +// Builder methods: +// +// Script(events ...ports.Event) — append raw events to the script. +// +// WithTerminalCompleted() — append EventWorkflowCompleted (terminal, closes channel). +// +// WithTerminalFailed(err error) — append EventWorkflowFailed with the +// application.MapError(err) ErrorCode as the event Payload. +// +// WithInputRequired(req ports.InputRequest) — append EventInputRequired with req +// as Payload. The pump goroutine pauses after emitting this event and +// resumes only when FakeSession.Respond is called. +// +// WithHistory(records ...ports.RunRecord) — seed records returned by +// Fake.History; useful for testing history-display code paths. +// +// # Respond Synchronization +// +// When the scripted sequence contains an EventInputRequired event, the ordering +// contract is: +// +// 1. Consumer reads EventInputRequired from sess.Events(). +// 2. No further event is available on the channel (pump is blocked). +// 3. Consumer calls sess.Respond(ports.InputResponse{...}). +// 4. Pump unblocks and emits the next scripted event. +// +// This models the real FacadeAdapter behavior where the workflow is paused +// awaiting user input. +// +// # Integration with the Conformance Suite +// +// T065 builds a cross-interface conformance suite that exercises all consumer +// packages (CLI, TUI, HTTP API, ACP) against a single shared Fake. +// Each consumer test creates a Fake with the scenario under test, calls the +// consumer entry-point, and asserts the resulting output or state. +// +// Import path: +// +// import "github.com/awf-project/cli/internal/testutil/facadetest" +// +// # Contract Compliance +// +// Fake satisfies the five-point port contract verified by +// internal/domain/ports/facade_contract_test.go: +// +// 1. Close is idempotent (multiple calls return nil). +// 2. Events channel is closed after Close. +// 3. Run with empty Identifier returns ports.ErrInvalidRequest. +// 4. Run with a cancelled context propagates the context error. +// 5. Respond after Close returns ports.ErrSessionClosed. +// +// TestFakeFacade_SatisfiesPortContract in facadetest_test.go re-runs these +// five assertions against Fake and FakeSession directly. +// +// # Thread Safety +// +// Fake is safe for concurrent calls to Run, History, and the builder methods. +// Each FakeSession is an independent instance; multiple sessions created from +// the same Fake do
