説明

The issue is in here and here. If the line/column is 0 unit tests will not care if the expected line/column matches that. Also see https://github.com/DotNetAnalyzers/StyleCopAnalyzers/pull/569.

調査方針: The issue points to two specific lines in DiagnosticVerifier.cs (lines 193 and 204) where the verification of diagnostics fails when line/column is 0. A similar fix was implemented in StyleCopAnalyzers PR #569, which can serve as a reference. The fix should ensure that when line/column is 0, the expected values are still compared. No linked PR or assignees exist, so work can start independently.
