Testing Your Work

You and your team are working on a lexicon-based sentiment snalysis application, and created a component that encapsulates the calculation of sentiment scores. This component will be re-used in many workflows, so it is important to make sure that it is behaving correctly. A principled way of accomplishing this is through automated unit testing. Given a sample of the data this component receives as input (input golden data), and a small table with the corresponding expected outputs (output golden data), your goal is to create a workflow that automatically tests this component (testflow).
