From 4f2cf5f51609656e0751e177f09614ae4a3cb58c Mon Sep 17 00:00:00 2001 From: Karim Jerbi Date: Thu, 27 Aug 2026 23:23:10 +0100 Subject: [PATCH] test(app): add chprop integration tests for handler dispatch and undo Add a new #[cfg(test)] mod chprop_integration_tests to src/app/properties.rs with four end-to-end tests that exercise the converted CHPROP / MATCHPROP handlers through the real Message dispatcher and the CLI command driver: - prop_color_change_multiple_entities_undo_redo: a colour change on two selected lines flows through Message::PropColorChanged -> the property-op handler -> apply_property_op, and is reversible via undo / redo. Seeds the panel's source_handles (selected_handles() is empty in this test setup) so the converted non-empty branch runs. - prop_change_on_locked_layer_is_ignored: when a selected entity's layer is locked, property_target_handles filters it out and the handler's empty-handles branch leaves the entity itself untouched. Asserts the entity-level invariant only; the empty branch updates the document header (CECOLOR) and sets dirty as a separate, pre-existing behaviour. - ribbon_lineweight_updates_after_change: the Home-ribbon Lineweight chip is updated by the converted RibbonLineweightChanged handler. Uses acadrust::types::LineWeight::from_value(50) (the real constructor; Lineweight::from_mm does not exist). - cli_chprop_undo_restores_previous_state: regression test for the CLI CHPROP command. Before Mission #15 it recorded the undo snapshot after mutating the entities, so undo restored the post-edit state (a no-op undo); converting the site to apply_property_op moved the snapshot before the mutation. #[ignore]d: CLI CHPROP dispatch via run_command_line / automation-op "run" does not reach the handler in this test setup. The helper-level invariant is already covered by apply_property_op_tests::applies_to_each_handle_sets_dirty_and_mutates and the strengthened missing_entity_does_not_abort_loop. The fifth proposed test (matchprop_empty_dest_no_dirty) was not added: MATCHPROP is the interactive command driver (source pick -> dest pick) and cannot be exercised from a unit test in isolation. The empty-handles early-return is already covered at the helper level by empty_handles_does_not_invoke_or_dirty. Setup lessons that shaped these tests (panel vs scene selection, LineWeight::from_value, the layer-locking pattern, undo not clearing dirty) are documented in MISSION_15_REVIEW.md section 6.2. Full suite: 478 passed / 1 pre-existing fail (diameter_dim_bakes_through_center, unrelated) / 5 ignored. No regression. No production code changed -- the new module is #[cfg(test)]-only. test app::properties::chprop_integration_tests::prop_color_change_multiple_entities_undo_redo test app::properties::chprop_integration_tests::cli_chprop_undo_restores_previous_state test app::properties::chprop_integration_tests::prop_change_on_locked_layer_is_ignored test app::properties::chprop_integration_tests::ribbon_lineweight_updates_after_change --- src/app/properties.rs | 176 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 176 insertions(+) diff --git a/src/app/properties.rs b/src/app/properties.rs index 7ab2e5603..d884905a7 100644 --- a/src/app/properties.rs +++ b/src/app/properties.rs @@ -3560,3 +3560,179 @@ mod apply_property_op_tests { ); } } + +#[cfg(test)] +mod chprop_integration_tests { + use crate::app::{Message, OpenCADStudio}; + use acadrust::entities::Line; + use acadrust::types::{Color, LineWeight, Vector3}; + + fn line_handle(app: &mut OpenCADStudio) -> acadrust::Handle { + let i = app.active_tab; + let mut line = Line::new(); + line.start = Vector3::ZERO; + line.end = Vector3::new(1.0, 0.0, 0.0); + app.commit_entity_handle(acadrust::EntityType::Line(line)) + .expect("line should commit") + } + + /// Full-handler integration: a colour change on a multi-entity + /// selection flows through `Message::PropColorChanged` -> the + /// property-op handler -> `apply_property_op`, and is reversible + /// via undo / redo.
