From cbefb11c0f143502b763e0070213a6bd1b67c5a1 Mon Sep 17 00:00:00 2001 From: Peter Chanthamynavong Date: Thu, 8 Jan 2026 14:32:12 -0800 Subject: [PATCH] test(dep): add regression tests for FK error messages (GH#952) (#964) - TestDepAdd_FKError: validates user-friendly error for invalid issue IDs - TestDepAdd_FKError_JSON: verifies JSON output mode - TestDepAdd_FKError_Daemon: tests daemon mode error wrapping - TestDepRemove_FKError: confirms dep remove behavior (N/A for FK errors) Discovery: Storage layer already pre-validates issue IDs before INSERT, so FK constraint errors don't occur at that layer. Tests serve as regression coverage ensuring error messages remain user-friendly. --- cmd/bd/dep_test.go | 324 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 324 insertions(+) diff --git a/cmd/bd/dep_test.go b/cmd/bd/dep_test.go index 8b9b4798..0c26bc5f 100644 --- a/cmd/bd/dep_test.go +++ b/cmd/bd/dep_test.go @@ -1084,6 +1084,330 @@ func TestMergeBidirectionalTrees_PreservesDepth(t *testing.T) { } // Tests for child→parent dependency detection (bd-nim5) +// ============================================================================ +// Foreign Key Error Tests (GH#952 Issue 4) +// ============================================================================ +// +// These tests verify that foreign key constraint violations produce +// user-friendly error messages instead of raw SQLite errors. +// +// Expected behavior: +// - Error should say "issue X or Y not found" (user-friendly) +// - Error should NOT say "FOREIGN KEY constraint failed" (raw SQLite) +// +// TRACER BULLET FINDING (Phase 1): +// The storage layer (dependencies.go) already validates issue existence +// BEFORE inserting into the database, so FK constraint errors don't occur +// at the storage layer.
