The quality of Delphi-to-C++ translations produced by Delphi2Cpp is ensured by a suite of test files. After the tests have been verified to run correctly in Delphi, the code is translated into C++ using Delphi2Cpp. The translated test files are then integrated into a C++ test application built with either C++Builder or Visual C++, where the tests are run again.
The examples below are only a small selection of the whole test suite, which comprises more than two hundred of such test files.
