- Each module can now have a Tests folder at its root containing low level tests written with Catch2 - Used like this: UnrealBuildTool.exe -Mode=Test TargetName Platform Configuration - It creates a test executable that's associated with the specified build Target and it includes all the tests for the Target AND all its dependencies as well - When building without -Mode=Test it will omit the Tests folder contents from compilation: in theory we never allowed folders named Tests at the root of modules, but there might be isolated exceptions where we didn't validate folder names - in this case we will need to move that Tests folder one level up for example - Code paths for test and non-test builds are entirely separated #jira UE-135280 #rb Jerome.Delattre #preflight 61e839d5276892ce10759205 [CL 18663474 by chris constantinescu in ue5-main branch]
