Author and run Unreal Engine's Automation Test Framework - Epic's C++ test framework for UE 4.x / 5.x, documented at dev.epicgames.com/documentation/en-us/unreal-engine. Covers the five test categories Epic defines (Unit / Feature / Smoke / Content Stress / Screenshot Comparison), the IMPLEMENT_SIMPLE_AUTOMATION_TEST and IMPLEMENT_COMPLEX_AUTOMATION_TEST macros, the BDD-style Automation Spec API (DEFINE_SPEC / BEGIN_DEFINE_SPEC / Describe / It / BeforeEach / LatentIt / xIt), latent commands (ADD_LATENT_AUTOMATION_COMMAND), the Automation Driver for UI input simulation (IAutomationDriverModule::Get().CreateDriver(), By::Id / By::Path locators), running via Session Frontend (Window > Test Automation) and command line (-ExecCmds="Automation RunTests …"), and CI integration. Use when the unit under test is C++ Unreal code that needs the UE runtime, editor, or UMG UI surface.
