/**
 * This unit test uses [Approvals](https://github.com/approvals/ApprovalTests.php).
 * 
 * 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.
