From 9d9def3f08d24d32cf1d3213975989afa488aa78 Mon Sep 17 00:00:00 2001 From: Jeroen Schweitzer Date: Sun, 31 May 2026 17:38:59 +0200 Subject: [PATCH] cover decisions list/detail + file-tree controller to hold the floor Wave A's widget tests pulled previously-untested files into the coverage denominator (the decision extension loads decisions_view; the file-tree tests load file_tree_controller), dropping total coverage to 93.6%. Add tests for DecisionsView (list render + tap-to-select, the T-188 publisher side), FileTreeController, and the remaining DecisionDetailView branches, restoring the total to 95.03%.
