// m4_acceptance.rs --- T M4.1 + T M4.2 + T M4.3 + T M4.4 + T M4.5 + T M4.6 acceptance gates.
|
||
|
||
//! Acceptance gates for Milestone 4.
|
||
//!
|
||
//! Per the spec, every M4.x acceptance bullet has an automated
|
||
//! regression test.
|
||
//!
|
||
//! # T M4.1 --- Tree-sitter integration
|
||
//!
|
||
//! 1. Initial parse of a 5000-line file under 100 ms →
|
||
//! `m4_1_initial_parse_of_5000_line_file_under_100ms`.
|
||
//! 2. Incremental parse on edit under 5 ms →
|
||
//! `m4_1_incremental_parse_under_5ms`.
|
||
//! 3. Parse tree introspectable via Lua →
|
||
//! `m4_1_parse_tree_introspectable_via_lua`.
|
||
//!
|
||
//! # T M4.2 --- Rust and Lua grammars wired up
|
||
//!
|
||
//! 1. Opening a `.rs` or `.lua` file produces a parse tree →
|
||
//! `m4_2_opening_a_rust_file_produces_a_parse_tree`,
|
||
//! `m4_2_opening_a_lua_file_produces_a_parse_tree`.
|
||
//! 2. Adding a new grammar requires only a config entry →
|
||
//! `m4_2_register_extension_attaches_for_a_runtime_added_extension`.
|
||
//!
|
||
//! # T M4.3 --- Syntax-highlight view
|
||
//!
|
||
//! 1. Rust file opens with full syntax highlighting under 100 ms →
|
||
//! `m4_3_open_rust_file_highlights_under_100ms` (release-gated).
|
||
//! 2. Highlight updates on edit within one frame after parse
|
||
//! completes → `m4_3_highlight_updates_within_one_frame_after_parse`.
|
||
//! 3. Theming via Lua-defined color schemes →
|
||
//! `m4_3_theming_via_lua_color_scheme`.
|
||
//!
|
||
//! # T M4.4 --- Process supervisor
|
||
//!
|
||
//! 1. Process lifecycle correctly handled (spawn, exit, signal,
|
||
//! crash) → `m4_4_lifecycle_spawn_and_exit`,
|
||
//! `m4_4_lifecycle_signal_terminates`,
|
||
//! `m4_4_lifecycle_crash_surfaces_as_event`.
|
||
//! 2. Restart policy honored →
|
||
//! `m4_4_restart_policy_on_crash_respawns`,
|
||
//! `m4_4_restart_policy_never_does_not_respawn`.
|
||
//! 3. No zombie processes after editor exit →
|
||
//! `m4_4_no_zombies_after_editor_drop`.
|
||
//! 4. PTY mode works for terminal-aware children →
|
||
//! `m4_4_pty_mode_child_observes_a_tty`.
|
||
//!
|
||
//! # T M4.5 --- LSP client core
|
||
//!
|
||
//! 1. `rust-analyzer` connects, initializes, and reports
|
||
//! capabilities → `m4_5_rust_analyzer_initializes` (gated on the
|
||
//! binary being on PATH; skipped silently otherwise).
|
||
//! 2. `didChange` notifications sent on edit →
|
||
//! `m4_5_did_change_notifications_go_out_after_edits`.
|
||
//! 3. Server crash auto-restarts; surfaced in status indicator →
|
||
//! `m4_5_server_crash_auto_restarts`.
|
||
//! 4. Protocol violations on either side surface as structured
|
||
//! errors → `m4_5_protocol_violation_surfaces_as_structured_error`.
|
||
//!
|
||
//! # T M4.6 --- LSP-backed views: diagnostics
|
||
//!
|
||
//! 1. Diagnostics update within 500 ms of last keystroke →
|
||
//! `m4_6_diagnostics_arrive_within_500ms`.
|
||
//! 2. Navigate-to-next-diagnostic command works →
|
||
//! `m4_6_navigate_next_diagnostic_wraps`.
|
||
//! 3. Diagnostic source visible →
|
||
//! `m4_6_diagnostic_source_field_is_preserved`.
|
||
//!
|
||
//! The non-rust-analyzer M4.5 tests run a tiny shell-script "echo
|
||
//! LSP" peer (`fake_lsp_server.sh`) that speaks just enough of the
|
||
//! protocol to exercise the framing, lifecycle, and dispatcher
|
||
//! without depending on a real language server being installed.
|
||
//!
|
||
//! Run with:
|
||
//!
|
||
//! ```sh
|
||
//! cargo test --test m4_acceptance
|
||
//! cargo test --release --test m4_acceptance -- --ignored --nocapture
|
||
//! ```
|
||
//!
|
||
//! Perf gates in M4.1 ((1) and (2)) and M4.3 (1) are `#[ignore]`'d
|
||
//! so they only run under the explicit `--release --ignored`
|
||
//! invocation --- the spec budgets are stated for release
|
||
//! optimization. Same convention as the M3 grep kernel gate.
