//! GPUI test harness for the input pipeline.
|
|
//!
|
|
//! Twelve sidecar-side commits and one shell-side commit had all claimed to
|
|
//! fix "click does nothing" while the user kept reporting the same symptom.
|
|
//! The roundtable consensus: every store-layer test passed GREEN, every
|
|
//! sidecar integration test passed GREEN, but nothing in the repo exercised
|
|
//! the real GPUI event tree (`render_input_overlay` + window-level mouse
|
|
//! handlers + sidebar capture interactions). This module is that missing
|
|
//! holdout set.
|
|
//!
|
|
//! What we have so far:
|
|
//! 1. `baseline_overlay_div_receives_simulated_click` — proves GPUI's
|
|
//! `.occlude()` + `capture_any_mouse_up` primitive works correctly in
|
|
//! `TestAppContext`. If this regresses, the harness itself is broken.
|
|
//! 2. `baseline_overlay_with_full_listener_combo_receives_click` — proves
|
|
//! the exact listener combo `render_input_overlay` uses (on_mouse_down +
|
|
//! capture_any_mouse_up + on_mouse_move + on_scroll_wheel on a single
|
|
//! `.occlude()` div) works in isolation.
|
|
//! 3. `ely_shell_external_canvas_lays_out_inside_window` — boots a real
|
|
//! `ElyShell`, navigates to an external URL, and asserts the
|
|
//! input_overlay's measured viewport bounds fit inside the visible
|
|
//! window. This was the original ship-blocker: the overlay was being
|
|
//! positioned at `y = window_height - 17`, entirely below the visible
|
|
//! region, so every user click hit empty space above the overlay.

either (a) reproduce the bug outside TestAppContext (file an \
