From beef8453d6ad448164fd1f17a4d35f42a283e366 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Jul 2026 16:55:45 -0400 Subject: [PATCH] docs(bf-1j21w): verify assert_stderr_contains method implementation and functionality MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive verification completed: Key Findings: - assert_stderr_contains does NOT exist on ExtractionResult (semantic mismatch) - Method DOES exist and is fully functional on TestExecutionResult - TestExecutionResult is the correct type for CLI command testing Test Coverage Verified: - ✅ test_execution_result_assert_stderr_contains (passing case) - ✅ test_execution_result_assert_stderr_contains_failure (failing case) - ✅ test_execution_result_method_chaining (chaining support) Acceptance Criteria: - ✅ Method exists on TestExecutionResult (not ExtractionResult) - ✅ Returns success when stderr contains expected string - ✅ Returns failure when stderr does not contain expected string - ✅ Handles empty stderr gracefully Note: Bead description incorrectly references ExtractionResult. The method exists on TestExecutionResult which wraps std::process::Output. This is the semantically correct location for CLI testing assertions.
