Add unit tests to Example App

MR: Pending

Description

When attempting to resolve an issue, the example app wasn't loading after clicking Start Web IDE . Although it's fixed now, when this happened, there wasn't any sort failing test to catch this. Therefore, to stay cautious, adding a test for this could be helpful in the future to prevent problems from escalating.

Implementation Details

• Setup testing for vue components
• Create test to catch when example test isn't loading
