//! Automated TUI smoke tests
//!
//! Prototype scaffolding for driving ChatWidget through scripted scenarios
//! and asserting rendered output. Inspired by docs/migration/tui-smoke-notes.md.
//!
//! TODO: This is a minimal scaffold. Future work:
//! - Extract test helpers from chatwidget::tests to a shared test module
//! - Implement event stream capture/replay for reproducibility
//! - Add comprehensive scenario coverage
//! - Hook into CI/CD for regression detection

#![cfg(test)]
#![allow(clippy::unwrap_used, clippy::expect_used)]

// NOTE: Currently these tests are stubs because the internal test helpers
// (make_chatwidget_manual, buffer_to_string) are not exposed to integration tests.
// They live in #[cfg(test)] mod tests inside src/chatwidget.rs.
//
// To make these tests functional, we need to either:
// 1. Move test helpers to a pub test module (e.g., src/chatwidget/test_helpers.rs)
// 2. Or keep tests as unit tests inside src/chatwidget/tests.rs
//
// For now, this file serves as documentation of the intended smoke test structure.

#[test]
fn smoke_test_scaffolding_exists() {
    // Placeholder to ensure the test file compiles.
    // TODO: Implement actual smoke tests once test helpers are accessible.
    //
    // Planned test scenarios:
    // 1. smoke_markdown_streaming - Drive ChatWidget with streaming markdown events,
    //    render to buffer, assert output contains expected content
    // 2. smoke_approval_flow - Simulate ApplyPatchApprovalRequest event,
    //    verify approval modal renders, test approval/rejection paths
    // 3. smoke_renders_without_crash - Basic sanity check that widget creation
    //    and rendering doesn't panic
    // 4. smoke_multi_turn_conversation - Simulate user input -> assistant response cycle
    // 5. smoke_tool_call_visualization - Verify tool call events render properly
    // 6. smoke_auto_mode_progression - Test auto mode state transitions and UI updates
    // 7. smoke_error_handling - Verify error events are displayed correctly
    //
    // Implementation approach (from chatwidget/tests.rs):
    // - Use make_chatwidget_manual() to get (ChatWidget, event_rx, op_rx)
    // - Drive via chat.handle_code_event(Event { ... })
    // - Render using ratatui::Terminal with TestBackend
    // - Extract buffer via buffer_to_string() for assertions
    assert!(true, "Smoke test scaffolding is in place");
