-/**
- * This unit test uses [Jest Snapshot](https://goo.gl/fbAQLP).
- * 
- * There are two test cases here with different styles:
- * <li>"foo" is more similar to the unit test from the 'Java' version
- * <li>"thirtyDays" is more similar to the TextTest from the 'Java' version
- *
- * I suggest choosing one style to develop and deleting the other.
