Bugfix — Issue #518: E_WARNING Undefined array key "testprojectName" in planAddTC.php:421

Summary

PHP 8.x emits E_WARNING: Undefined array key "testprojectName" when planAddTC.php accesses $_SESSION['testprojectName'] without checking if the key exists.

Root Cause

• File: lib/plan/planAddTC.php:421 (pre-fix line)
• Code (before fix): $args->tproject_name = $_SESSION['testprojectName'];
• Cause: $_SESSION['testprojectName'] is only set on certain navigation paths (after selecting a project in the navbar). When the page is loaded directly or via a refresh where the session key is missing, PHP 8 emits E_WARNING.
• Regression source: PHP 8 changed undefined array key access from E_NOTICE (suppressible) to E_WARNING (always logged).

Fix

Method: Added isset() ternary guard.

// Before (line 421):
$args->tproject_name = $_SESSION['testprojectName'];

// After (line 421):
$args->tproject_name = isset($_SESSION['testprojectName']) ? $_SESSION['testprojectName'] : '';
