Can you print/write the result of screen.debug() to a file?

In one of my tests I am expecting some kind of DOM change. However, the page it's on is quite long.

So what I usually do for smaller components is to use screen.debug() method. But since the file is quite long, I started to also run the test task with DEBUG_PRINT_LIMIT=50000. Now that eventually got the result I got.

But that made me wonder, is it perhaps possible to save the output in a file?

According to the docs, screen.debug is essentially a shortcut for console.log(prettyDOM()).

So you could just use prettyDOM() directly, and do whatever with the result.

I would do copy(prettyDOM()) to put it on the clipboard and then paste it in a text file manually (in Chrome) or save it into a file (in node).
