That might work. So the idea would be a utility class not tied to a JUnit5 annotation? The usage would then be adding a call to that while debugging a test wherever it makes sense for your test, possible from an AfterEach method.

What would this do? I can see the usefulness of returning a WritableImage (basically calling `Robot::getScreenCapture` on the whole screen) or a base64-encoded PNG file, but what does it mean to return a raw byte array? I probably wouldn't recommend this one.

This seems useful, although what are "prefix" and "postfix" for?
