This repository has the objective to demonstrate a problem that may occur when you save screenshots in protractor. If some error occurs, then the process immediately exits, and your screenshot may not be saved.
To solve this problem there is a fix on the branch named correction. It basically tracks the relevant open streams and
wait for them to close in the property afterLaunch of the protractor configuration. If you know a cleaner solution
to this problem, feel free to make a pull request.
