Challenge 23: Testing Your Work
Level: Medium

Description: 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). Note: Read more about how to perform testing in KNIME here. Note 2: Read more about lexicon-based sentiment analysis here.
