// TestSearchCommand_HelpErrorHandling verifies that the search command handles
// Help() errors gracefully.
//
// This test addresses bd-gra: errcheck flagged cmd.Help() return value not checked
// in search.go:39. The current behavior is intentional:
// - Help() is called when query is missing (error path)
// - Even if Help() fails (e.g., output redirection fails), we still exit with code 1
// - The error from Help() is rare (typically I/O errors writing to stderr)
// - Since we're already in an error state, ignoring Help() errors is acceptable
func TestSearchCommand_HelpErrorHandling(t *testing.T) {
	// Create a test command similar to searchCmd
	cmd := &cobra.Command{

			if len(args) > 0 {
				query = args[0]
			}

			if query == "" {
				// This is the code path being tested
				_ = cmd.Help() // Intentionally ignore error (bd-gra)
				// In real code, os.Exit(1) follows, so Help() error doesn't matter
			}
		},

	// Test 1: Normal case - Help() writes to stdout/stderr
	t.Run("normal_help_output", func(t *testing.T) {
		cmd.SetOut(&bytes.Buffer{})
		cmd.SetErr(&bytes.Buffer{})

		// Call with no args (triggers help)

	})

		err := cmd.Execute()

		// Even if Help() fails internally, cmd.Execute() may not propagate it
		// because we ignore the Help() return value
		t.Logf("cmd.Execute() returned: %v", err)

		// Key insight: The error from Help() is intentionally ignored because:
		// 1. We're already in an error path (missing required argument)
		// 2. The subsequent os.Exit(1) will terminate regardless
		// 3. Help() errors are rare (I/O failures writing to stderr)
		// 4. User will still see "Error: search query is required" before Help() is called
	})

// TestSearchCommand_HelpSuppression verifies that #nosec comment is appropriate
func TestSearchCommand_HelpSuppression(t *testing.T) {
	// This test documents why ignoring cmd.Help() error is safe:
	//
	// 1. Help() is called in an error path (missing required argument)
	// 2. We print "Error: search query is required" before calling Help()
	// 3. We call os.Exit(1) after Help(), terminating regardless of Help() success
	// 4. Help() errors are rare (typically I/O errors writing to stderr)
	// 5. If stderr is broken, user already can't see error messages anyway
	//
	// Therefore, checking Help() error adds no value and can be safely ignored.
