Description

As you include the library into the robot it binds itself into the robot test case and does not matter which robot keyword has failed makes a screenshot and binds the screenshot into the log under the failing keyword.

This feature would be an optional feature which could activated or deactivated through an initial argument while importing the library. Or another keyword.
