If you use Perforce to get the Unreal Engine source code, you'll also find precompiled binaries in the same Engine/Extras/Redist/en-us folder of the Perforce repository. You can find the installer, with separate executables for 32-bit and 64-bit Windows, in the Engine/Extras/Redist/en-us folder under your Unreal Engine installation location.

It pays to Run CTest to build all test targets.Īfter this, you should see all tests in the testing pane on the left.

Testmate discovers tests only after they are built.

This information is retrieved from the current debug configuration.

Potential sources for missing DLLs are C:\msys64\mingw64\bin, C:\msys64\mingw64\x86_64-w64-mingw32\lib, and the build folder itself.įor test discovery, C++ Testmate needs to know the location of all additional dependencies. When executing the program via command line or explorer a message box should prompt which DLLs are missing.Ī simple solution is to copy the according DLLs into the folder of the executable.Īnother solution is to make the path available by extending the PATH environment variable. The most effective way to debug startup issues is by means of the Process Monitor.īut normally, its a missing DLL.
