The Test harness should provide an OCRHelper method that would delegate to software like `tesseract` to read the screen content. That would make it very handy to test some cases of rendering like code minings.
Command I tried successfully is `tesseract /path/to/screenshot.png stdout -psm 6` for a text editor; we can replace the path/to/screenshot by stdin and send the image of the widget to stdin stream.
Usage could look like
```
styledText.setText("class A {}");
assertEquals("0 references\nclass A {}", OCRHelper.read(styledText))
```
