ScreenshotAnalyzer

A screenshot of the current window contents which can be analyzed in tests.

Header:	#include <AUI/Test/UI/ScreenshotAnalyzer.h>
CMake:	aui_link(my_target PUBLIC aui::uitests)

Detailed Description

Most of the time, you don't need this class directly; averageColor and pixelColorAt assertions use it. Use it when you need something custom:

auto screenshot = ScreenshotAnalyzer::makeScreenshot().clip(By::name("#preview").one());
EXPECT_EQ(screenshot.image().size(), glm::uvec2(64, 64));

See Screenshots and pixels.
