Read Original

The article details a developer's experience fixing a long-standing memory leak in the DUnit unit testing framework's TextTestRunner. The leak was caused by calling Halt without freeing TTestResult and TTestSuite objects. The author provides the fix, discusses the abandoned state of DUnit, and briefly mentions a useful DUnit extension and the importance of enabling memory leak reporting.
