Selenium: chrome driver makes screenshot just of visible part of page

Question

I need to do screenshot of full page using chrome driver, but it makes it partly.

File screenshotFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

The screenshot looks as visible rectangle with correct information and big black area below.

Answer 1

This is a known bug: https://code.google.com/p/chromedriver/issues/detail?id=294 (Only for Chrome driver, firefox driver works fine)

Answer 2

Might worth trying to use this library:

To make a full page screenshot:

Shutterbug.shootPage(driver, ScrollStrategy.BOTH_DIRECTIONS).save();

(it uses scroll-and-stitch method)

Sources on github https://github.com/assertthat/selenium-shutterbug

Provides ability to make full page screenshot in Chrome and some other extended features, tested on Windows and OS X.
