From d2e65d88211c64973a5e3f862a6f697f2dd47dcf Mon Sep 17 00:00:00 2001 From: Jeroen Schweitzer Date: Mon, 11 May 2026 09:15:29 +0200 Subject: [PATCH] test sweep: cover ui/render.dart (T-91) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 10 widget tests driving RenderTerminal through a hosted TerminalView: the reactive setters via updateRenderObject (theme, textStyle, textScaler, padding, autoResize, cursorType, alwaysShowCursor) and direct setter calls on the render box (padding, onEditableRect, composingText) to cover the value-changed branches; getOffset for non-origin cells; systemFontsDidChange; the terminal listener via write(); the viewport-offset listener via scrollback overflow; and the paint paths for composingText and controller-driven highlights. Coverage: render.dart 179/249 -> 245/249 (98%). The 4 still-uncovered lines are the _onScroll body — reachable only when the inner ViewportOffset notifies, which doesn't happen with the current ViewportOffset.zero() wiring (scroll lives in PointerScrollEvent → PgUp/PgDown). Total 71.23% -> 72.02%; floor bumped to 72.
